A program that draws graphs of functions. Graph for plotting mathematical functions. Organize data in an Excel worksheet

Almost any mathematical function can be visualized as a graph. In order to help users who have encountered certain difficulties in building them, a huge number of different programs have been developed. The most common and useful of them will be discussed below.

3D Grapher is one of the programs for plotting function graphs. Unfortunately, its capabilities do not include the creation of two-dimensional graphs; it is designed only for visualizing mathematical functions in the form of three-dimensional images.

In general, this software provides a very high-quality result, and also provides the opportunity to track changes in the function over time.

AceIT Grapher

Another program in this category that cannot be ignored is AceIT Grapher. Like 3D Grapher, it provides for the creation of three-dimensional graphs, however, in addition, it is not without the ability to display the appearance of functions on a plane.

It is very nice to have a tool for automated research of a function, which allows you to avoid long calculations on paper.

Advanced Graph

If you're looking for really high-quality function graphing software, then Advanced Grapher is worth a look. This tool, in general, has a similar set of capabilities to AceIT Grapher, but there are some differences. It is important to have a translation into Russian.

It is worth paying attention to extremely useful tools for calculating derivatives and antiderivative functions, as well as displaying them on a graph.

Dplot

This representative of the category under consideration is a little more difficult to handle. With this program, you can perform all the same functions with the functions as in the case of the previous two, but this may require certain preparations.

The main disadvantage of this tool can be confidently called the extremely high price for the full version, which makes it not the best option, because there are other solutions to the problems that arise when constructing graphs of mathematical functions, for example, Advanced Grapher.

Efofex FX Draw

Efofex FX Draw is another function graphing program. Pleasant visual design, coupled with a wide range of capabilities that are not inferior to its main competitors, allow this product to take its rightful place in its segment.

A pleasant difference from competitors is the ability to plot statistical and probabilistic functions.

Falco Graph Builder

One of the tools for constructing function graphs is Falco Graph Builder. In terms of its capabilities, it is inferior to most similar programs, if only because it provides the ability to build only two-dimensional graphs of mathematical functions.

Despite this, if you do not need to create voluminous charts, then this representative can be an excellent choice, at least because it is completely free.

FBK Grapher

A program created by Russian developers from FBKStudio Software, FBK Grapher is also a worthy representative of this category of software. Possessing all the necessary tools for visualizing mathematical expressions, this software, in general, is not inferior to foreign analogues.

The only thing that FBK Grapher can be reproached for is that the design of three-dimensional graphs is not the most pleasant and understandable.

Functor

Here, as in 3D Grapher, it is possible to create only three-dimensional graphs, however, the results of this program are very specific and not very rich in details, because they do not have any symbols.

Given this fact, we can say that Functor is suitable only when you only need to get a superficial idea of the appearance of a mathematical function.

GeoGebra

Creating graphs of mathematical functions is not the main task of the program, because it is intended to perform mathematical operations in a broader sense. Among these are the construction of various geometric shapes and interaction with them. Despite this, this software copes, in general, with creating function graphs no worse than specialized programs.

Another plus in favor of GeoGebra is that it is completely free and is constantly supported by its developers.

Gnuplot

This software is the most different from its competitors in the category under review. The main difference between this program and its analogues is that all actions with functions in it are performed using the command line.

If you do decide to pay attention to Gnuplot, then you need to know that it is quite difficult to understand how it works and is recommended for users who are familiar with programming at least at a basic level.

The programs presented above will help you understand the construction of a graph of a particular mathematical function of almost any complexity. Almost all of them work on a similar principle, but some have a wider range of features, making them the best options to choose from.

If you have Excel installed on your computer, you can take advantage of Word's advanced charting capabilities.

About charts

Charts are used to present series of numerical data in a graphical format that makes it easier to understand large amounts of information and the relationships between different data series.

1. Sheet data

2. Chart created from worksheet data

Excel supports different types of charts, which allows you to present data in the most understandable way for a particular audience. When you create a new chart or edit an existing chart, you can choose from a variety of chart types (such as bar chart or pie chart) and subtypes (such as stacked bar chart or 3-D pie chart). By combining different types in one chart, you can create a mixed chart.

An example of a mixed chart that combines a histogram and a graph.

For more information about the chart types supported in Excel, see Chart Types.

Chart elements

A diagram consists of various elements. Some of them are displayed by default, others can be added as needed. You can change the appearance of chart elements by moving them to a different location or changing their size or format. You can also remove chart elements that you don't want to display.

1. chart area.

2. diagram plotting area.

3. Data points for a series of data marked on a chart.

5. Chart legend.

6. Names of the chart and axes that can be used in the chart.

7. data label, which can be used to indicate the information of a data point in a data series.

Modify the base chart to suit your needs

Once you've created a chart, you can change any of its elements. For example, you can change the appearance of the axes, add a chart title, move or hide the legend, and add additional elements.

To change the chart you can do the following:

Change the appearance of the chart axes. You can specify the scale of the axes and change the spacing between values or categories. To make the chart easier to read, you can add tick marks on the axes and specify the amount of space between them.

Adding titles and data labels to a chart To help explain the data displayed in a chart, you can add a chart title, axis titles, and data labels.

Adding a legend and data table. You can show or hide the legend, change its location or elements. For some charts, you can also display a data table that contains the legend keys and values represented in the chart.

Apply special parameters for different types of charts. For different chart types, you can apply a variety of special lines (such as swing corridors and trend lines), bars (such as up and down bars and error bars), data markers, and so on.

Use ready-made chart styles and layouts for a professional look

Instead of adding or changing chart elements and formatting them manually, you can quickly apply a pre-made chart layout or style to your data. Word has many useful pre-designed layouts and styles that you can use as is or customize by manually changing the layout or format of individual chart elements, such as the chart area, plot area, data series, and legend.

When you use a preset chart layout, the chart displays a specified set of elements (for example, titles, legend, data table, or data labels) in a specific order. You can select a suitable layout from those provided for a specific chart type.

When you use a preset chart style, the chart's formatting is based on the document theme applied, so the chart's appearance will match the theme colors (set of colors), theme fonts (set of heading and body text fonts), and theme effects (set of borders and fills) that your organization or organization uses. specified by the user.

You can't create your own chart styles or layouts, but you can create chart templates that contain the layout and formatting you want.

Attractive chart formatting

In addition to using a preset chart style, you can easily change the formatting of individual chart elements, such as data markers, chart area, plot area, numbers, and text in titles and captions, which will attract attention and make the chart stand out. You can also apply shape styles and WordArt styles, or manually format shapes and text in chart elements.

To add formatting you can do the following:

Filling diagram elements. To draw attention to certain chart elements, you can fill them with color, texture, pattern, or gradient.

Change the outlines of chart elements. To highlight chart elements, you can change the color, type, or thickness of the lines.

Adding special effects to chart elements To complete your diagram, you can apply special effects to its elements, such as shadow, reflection, glow, smooth edges, embossing, or volumetric rotation.

Formatting text and numbers Text and numbers in chart titles, labels, and legends can be formatted in the same way as text and numbers on a worksheet. You can even apply WordArt styles to highlight text or numbers.

Reusing diagrams by creating templates

If you want to reuse a customized chart, you can save it as a chart template (CRTX file) in the Chart Templates folder. When you create a chart, you can apply a template in the same way as a built-in chart type. Chart templates are custom chart types that allow you to change the type of an existing chart. If you need to use a particular chart template frequently, you can save it as the default chart type.

Step 1: Create a Basic Chart

You can add a chart to a Word document in one of two ways: by embedding it, or by inserting an Excel chart that is linked to data in an Office Excel 2007 worksheet. The main differences between embedded and linked charts are where the data is stored and how it is updated after it is inserted into Word document.

Note: Some types of charts require data to be arranged in a specific way on the Excel worksheet. For more information, see .

Inserting a diagram by embedding it in a document

If an Excel chart is embedded in a Word file, it will not change even if you change the original Excel file. Embedded objects become part of the Word file and are no longer part of the original file.

Because the data is stored entirely in a single Word document, embedding is useful when you don't want it to change based on changes to the source file, or you don't want recipients of the document to have to update related information.

Insert a linked Excel chart into a document

You can create a chart in an external Excel 2007 worksheet, copy it, and paste a linked version into a Word document. If a chart is linked, the data in it is updated when the external Excel worksheet changes. The associated data is stored in an Excel sheet. A Word document stores only the location of the source file and displays a view of the associated data.

In Excel, select a chart by clicking its border and then on the tab home in Group Clipboard click Cut.

The chart will be deleted, but its data will remain in Excel.

In Word, click where you want to insert the chart in the document.

On the tab home in Group Clipboard click the button Insert.

Button Paste Options indicates that the chart will be linked to Excel data.

Save the Word document with the chart linked to the Excel data.

When you reopen the Word document, click Yes to update Excel data.

You can also create visual representations of your data using SmartArt graphics. For more information, see Create a SmartArt graphic.

Organize data in an Excel worksheet

Most charts, such as histograms and bar charts, can be drawn from data arranged in the rows or columns of a worksheet. However, some types of charts, such as pie and bubble charts, require the data to be arranged in a specific way.

Add the data to the worksheet that you want to use to create a chart.

You can arrange your data in rows or columns - Excel will automatically determine the best way to construct the chart. Some chart types, such as pie and bubble charts, require data to be arranged in a specific way, as described in the table below.

Stock chart

By column or row in the following order, using titles or dates as labels:

high, low and closing values

For example:

	Maximum		Closing


Maximum

Closing

Select the cells containing the data you want to use to create the chart.

Advice: If you select only one cell, Excel automatically builds a chart based on the adjacent cells that contain data. If the cells you want are not in a contiguous range, you can select nonadjacent cells or ranges; in this case, the selection should be a rectangle. You can also hide rows and columns that you don't want to appear in the chart.

Select cells, ranges, rows, and columns

To highlight	Follow these steps
Single cell	Click a cell or use the arrow keys to move to the desired cell.
Cell range	Click the first cell of the range, and then drag the mouse to the last cell of the range. You can also press the SHIFT key and use the arrow keys to expand the selection. Alternatively, you can select the first cell of a range and then press F8 to expand the selection using the arrow keys. To stop expanding the selection, press F8 again.
Large cell range	Click the first cell in the range, and then Shift-click the last cell in the range. Scroll to display the last cell.
All sheet cells	Click the button Select all. You can also press CTRL+A to select the entire sheet. If the table contains data, pressing CTRL+A selects the current range. Pressing CTRL+A again will select the entire table.
Non-adjacent cells or ranges of cells	Select the first cell or range of cells, and then hold down the CTRL key while selecting other cells or ranges. You can also select the first cell or range of cells, and then press Shift+F8 to include other nonadjacent cells or ranges in the selection. To stop turning on cells and ranges, press Shift+F8 again. Note: You cannot deselect individual non-adjacent cells or ranges without deselecting the entire selection.
Entire column or row	Click the timeline or column heading. 1. Row header 2. Column header You can also select cells in a row or column by selecting the first row and then pressing CTRL+SHIFT+ARROW (RIGHT or LEFT for rows, UP or DOWN for columns). If a row or column contains data, pressing CTRL+SHIFT+ARROW will highlight the row or column up to the last filled cell. Pressing CTRL+SHIFT+ARROW again will select the entire row or column.
Adjacent rows or columns	Drag your mouse over the row or column headings. You can also select the first row or column, and then press SHIFT to select the last row or column.
Non-adjacent rows or columns	Select the row or column header of the first row or column of the selection, and then press CTRL to click the column or row headers that you want to add to the selection.
The first or last cell in a row or column	Select a cell in a row or column, and then press Ctrl+ARROW (RIGHT or LEFT for rows, UP or DOWN for columns).
The first or last cell in a Microsoft Office Excel worksheet or table	To select the first cell in an Excel worksheet or list, press CTRL+HOME. To select the last cell that contains data or formatting in an Excel worksheet or list, press CTRL+END.
Cells up to the last used worksheet cell (lower right corner)	Select the first cell, and then press CTRL+SHIFT+END to expand the selection to the last cell in the worksheet you use (bottom right corner).
Cells before the beginning of the sheet	Select the first cell, and then press CTRL+SHIFT+HOME to expand the selection to the beginning of the sheet.
More or fewer cells than there are in the active selection	While holding down the SHIFT key, click the last cell you want to include in the new selection. The new selection will include a rectangular range between the active cell and the cell that was clicked.

To deselect cells, click any cell on the worksheet.

To quickly create a chart based on the default chart type, select the data you want and press Alt+F1. Pressing ALT+F1 creates an embedded chart.

When you create a chart, Excel determines the orientation of the data series based on the number of worksheet rows and columns that are included in it. After creating a chart, you can change the way the rows and columns are displayed in the chart by swapping them.

If the diagram is not needed, you can delete it. Click the chart to select it, and then press DELETE.

Step 2: Change the chart layout or style

Once you create a chart, you can instantly change its appearance. Instead of manually adding or changing chart elements or formatting, you can quickly apply a preset layout and style to your chart. Word provides a variety of useful chart layouts and styles (or Quick Layouts and Quick Styles) to choose from; If necessary, you can further customize the layout or style by manually changing the layout and format of individual chart elements.

Graph is a powerful and free tool for students, schoolchildren and scientists to create graphs of mathematical and trigonometric functions. The program allows you not only to set a function by which a graph is automatically constructed, but also to add a lot of additional elements, including rows of points, tangents or perpendiculars, approximation curves, and labels. In Graph, you can easily calculate the length of a curve, the integral area, you can shade the graph area, view the function values, and export the graph to a file.

When we first launch Graph, we only see the x and y axes in the program window. As you move the mouse over the graph area, the status bar displays the current cursor coordinates for each axis.

To add a function that will be used to build a graph, click the button [Add new feature] or key Insert. First of all, you need to select the type of function, Graph supports standard, parametric and polar functions. Then, depending on the selected type, we enter the function itself in one or more fields (f(x), x(t) and b y(t), r(t) respectively. Conventional symbols are used here, for example, the degree is written as ^, multiplication with an asterisk *. Argument range from, to, and step are optional, as are the start and end markers of the line. But it is advisable to customize the curve style. We can specify the line type, color and thickness, as well as style (lines, dots). Finally in the field signature text Enter, if necessary, the name of the function. If you leave this field blank, the function itself will be indicated on the graph.

Graph instantly builds a graph for a given function. To make changes to a function, just double-click on it in the list of functions on the left. By the way, the program allows you to simultaneously display several function graphs in one picture. By enabling or disabling checkboxes in the list, you can quickly adjust the visibility of charts. The frame with graph captions can be easily moved in the graph area.

It would seem that the program builds a graph for any given function and, in general, nothing else is needed. However, the Graph developers have provided a lot of additional features. For example, creating a tangent or perpendicular to a function. Press the button [Add a new tangent or perpendicular (normal) to the selected function] or key F2 and enter the line parameters. The required parameter is the x value. The rest of the settings are already familiar to us. The line type can be specified as dashed. The new tangent is also displayed in the function list and in the labels.

The function of painting a selected area on a chart is very useful. Select a function from the list and press the button [Shade part of the graph](or F3). Then we set the parameters for shading the area. Graph provides the following hatching methods:
- between function and x-axis;
- under the function;
- above the function;
- between the function and the y-axis;
- inside a function;
- between functions.
Beyond the tab Plot is there some more Settings, where you can specify the name of the selected area of the graph, as well as the color and type of hatching, display of the border and, if necessary, the range relative to the intersection.

The shaded area appears in the list of functions and in the label area. You can change it the same way as any other element - by double-clicking in the list of functions.

Button [Add a series of points] opens a settings window for plotting several points with specified coordinates. Enter the name of the row, and manually indicate the x and y coordinates of each point. Here we select the type of coordinates (rectangular, polar); type, color and size of markers (there are round, square, triangular, diamond-shaped, etc.). Points can be connected by a line; in the settings you can set its type, color, thickness and interpolation (linear, one-dimensional cubic spline, two-dimensional cubic spline, semi-cosine). In addition, near each point you can display its coordinates; their location is selected in the drop-down list. In a separate tab we set the error.

After creating a series of points, the button becomes active [Add approach curve for selected row of points], which allows you to add a trendline. In the Graph settings, select the type of trend line (linear, logarithmic, polynomial, power, exponential, moving average), line type, color and thickness. In the tab Custom several more types of trend lines: BET model, Exponential association, Hyperbolic fit, Rational function, Reciprocal, Saturation-Growth rate and Sinusoidal.

It is no longer possible to change the trendline type for the approach curve, so in this case it is necessary to delete the line and create it again.

Button [Function values] opens additional fields on the left to view function values depending on the specified x. Simply enter the x value manually and look at the function values here. In this case, the location of the point is shown with dotted lines on the graph.

Button [Show table of values] opens a window where you can get a list of values for a given range (fields From And Before) and step. Just click [Computing] and the complete list will appear in the table. Directly in the table, you can select a range of rows and cells and right-click to call up a context menu that allows you to copy values to the clipboard or export them to a file. Graph provides the ability to export values to CSV and TXT files.

Button name [Calculate path length using a function between two points] speaks for itself. We only need to select a section of the curve. This is done easily - click on the curve and, holding down the left mouse button, darken the curve. The calculated curve length is immediately displayed. The range can also be set using fields From And Before.

Another button with a “talking” name [Calculate the definite integral on the given interval] allows you to calculate the area enclosed by a function curve. Here we also select a section of the curve and instantly obtain the calculated value of the area using the integral.

In Graph you can create labels on a chart, which are essentially ordinary text labels. However, you can put a special character in a label, as well as an object, such as a formula created in Microsoft Equation.

On the menu Editing - Axes Graph developers offer all kinds of settings for the appearance of the axes and coordinate grid. Here you can configure the minimum and maximum value of each axis, the tick interval, grid display, and the inclusion of a logarithmic scale. You can also change the label of each axis in Graph. Many graphs use other quantities, such as time and distance, mass and volume, etc. In the tab Options set the title of the graph and its location. You can also customize the background color, axes and grid, label fonts, axes and numbers.

Finally, we note the ability to export the graph to a graphic file in EMF, SVG, BMP, PNG, JPG or PDF format. Enough for this on the menu File select item Save as image. And, of course, the graph and functions can be saved in a special Graph format, and later loaded and continued editing. To quickly copy only the graph to the clipboard, go to the menu Editing - Copy Image.

Graphing a function online

TOP 4 best online charting services

The Graph program is a powerful tool. It is offered free of charge and is intended not only for schoolchildren and students, but will also help scientists create graphs of trigonometric and mathematical functions. In addition, a lot of additional elements are provided.

These include marks, points, tangents, perpendiculars, and approximation curves. The utility will easily calculate the length of the curve, allow you to shade a certain section of the graph, and calculate the area using the integral. Using it, you can export data to a file or view the value of a function.

Using Graph

After the program is launched for the first time, you can see the X and Y axes. As you move the cursor with the mouse, the current coordinates for each of them will be displayed. To add a function for plotting, you must click the corresponding button. You can also use the Insert key. First, it is recommended to decide on the type of function. The program supports three types: standard, polar and parametric. After this, you should enter the function itself in the appropriate fields, depending on the selected type. In this case, generally accepted signs are used. For example, multiplication is indicated by an asterisk.

It is worth noting that the range of the argument step, to and from need not be specified. There is no need to set end and start line markers. You can specify its type, thickness, color, style. If necessary, enter the name of the function in the “Signature text” field. You can also leave it blank. In this case, the function itself will be indicated on the graph. The program can instantly create a graph. To make changes to a function, you must double-click on it. It is in the list on the left. Thus, the software makes it possible to construct several graphs simultaneously in one picture. Their visibility is adjusted by turning checkboxes in the list on and off. The frame with captions can be easily moved in the graphics area.

Additional features

At first glance, it may seem that the program simply creates a graph for a given function. But it also provides other possibilities. This applies to creating a perpendicular or tangent. Simply click the appropriate button and enter the line parameters. The X value is required. The line can be of the dashed type. The new tangent will appear in the function labels and list.

Hatching Methods The function of sketching a specific area on a graph is very useful. To do this, select the appropriate button from the list. After this, the hatching parameters are adjusted. There are the following types:

Above function;
under function;
between the X axis and the function;
inside a function;
between the Y axis and the function;
between functions.

In addition to the “Plots” tab, there is also “Settings”. There you can name the selected area of the graph, set its color and hatch type. In addition, it is possible to define the display of the border, as well as the relative intersection range, if necessary. As a result of the actions performed, the shaded area will appear in the list of functions. By double-clicking, you can change the parameters of this area.

Drawing points

A button with the appropriate name allows you to open a window where you can make the required settings. It is possible to plot several points with specific coordinates on the graph. You need to enter the row name and specify the coordinates manually. Here you need to select their type. They come in rectangular, polar and others. You can also choose the color, type, size of markers. It is possible to connect the graph points with a line. Then you will need to set its color, type, thickness, interpolation. Similar actions are carried out in the settings. Interpolation can be linear, act as a one-dimensional or two-dimensional cubic salin, or semi-cosine. Near the points you can display their coordinates by selecting the required parameters in the list. Then you can set the error, which is done in a separate tab.

After the points are created, a button is activated that makes it possible to add a trendline. The program settings allow you to select its type. It can be logarithmic, linear, power, polynomial, moving average, exponential. The Custom tab provides several more types of trendlines. To change its type for the approach curve, you will need to delete the line and then create it again.

Using Basic Keys

Using the button called “Function Value” you can open additional fields on the left. This is necessary to view the value of the function taking into account the given X. The graph displays the points with dotted lines. When you use the Show Value Table button, you can open a window that provides a list of values for the selected step and range. To do this, click “Calculations” and it will pop up in the table. There you can also select a range of cells and rows. Right-clicking will open a context menu. It allows you to copy values to the buffer. In addition, the context menu allows you to export them to a CSV and TXT file format.

There is also a button that is necessary to calculate the path length using a function between points. The user only needs to specify the area of the curve. It's easy to do. Just click on it, after which you should darken it by holding down the left mouse button. The length of the curve is immediately displayed. The From and To fields allow you to specify a range.

The program is equipped with another button, which performs an important function. It is provided for calculating the area that is limited by a curve function. It is necessary to designate an area, after which the resulting value is instantly displayed. Thus, the integral is calculated over a given interval.

The program provides the ability to create marks on the chart. They are ordinary inscriptions in the form of text. True, this label contains a special character or object. It can be a formula created in Microsoft Equation.

Functions of some tabs

The Edit program menu contains a section called Axes. There, the developers created various settings for the appearance of the coordinate grid, as well as the axes. It is possible to set the minimum and maximum values for each of them. In addition, it is proposed to determine the interval of ticks, the inclusion of a logarithm scale, and the display of a grid.
