Use this to create a new coordinate system for drawing graphs in.

Reads an earlier saved coordinate system from a .grf file.

Saves the coordinate system to a file.

Saves the coordinate system to a file with a new name.

Saves the shown coordinate system as an image.

Imports the contents of another Graph file into the current coordinate system.

Imports one or several point series from a tab, comma or semicolon separated data file. The first column shall contain the x-coordinates. The following columns shall contain the y-coordinates. Graph will create as many point series as there are columns with y-coordinates in the file. There is no limit to the number of point series possible in the data file as long as they share the same x-coordinates.

Sends the coordinate system and graphs to a printer.

Quits the program. You may be asked to save the file.

Use this to undo the last thing you did. You can choose how many undo steps that are saved in the Options dialog.

Use this to redo the last thing undone. This is only available after you have selected Edit → Undo.

This will copy the selected graph element to the clipboard. The element will be deleted afterwards.

This will copy the selected graph element to the clipboard.

This will paste an earlier copied graph element from the clipboard into the coordinate system.

Copies the shown coordinate system to the clipboard as an image. You can then paste it into another program, i.e. Microsoft Word.

Edit specifications for the axes, e.g. scale, colors, legend placement, etc.

This will change global settings for Graph, e.g. association of .grf files, showing of tooltips, maximum number of undo stored undo steps, etc.

Inserts a function into the coordinate system. Functions may be added with different width and color, and you can choose to only show the graph in a specified interval, and specify other settings too.

Use this dialog to add a tangent to an already shown function at a user-specified point. The tangent will be added to the function selected in the function list.

This menu item is used to add a shading to the selected function. You may choose between different styles of shading and different colors. The shading may be added above the function, below the function, between the function and the x-axis, between the function and the y-axis, inside the function or between two functions.

This dialog is used to add the first derivative to the selected function.

Inserts a new point series into the coordinate system. An infinite number of points defined by their x- and y-coordinates may be added. It is possible to choose color, size, and style of the point series.

Inserts a trendline as the curve of best fit for the selected point series. You may choose between different kinds of functions for the trendline.

This inserts an equation or inequality into the coordinate system. Equations and inequalities are used to express relations between x- and y-coordinates with the same operators etc. as for graphs of functions. Relations may be added with different shading styles and colors.

This will show a dialog, which may be used to create a formatted text label. The label will always be created at the center of the graphing area but can afterwards be dragged to another place with the mouse.

This will show a dialog where you can change the selected graph element in the function list.

This will delete the selected graph element in the function list.

This shows a dialog used to create custom functions and constants in addition to the built-in ones.

This will zoom in at the center of the graphing area, so you will see 81% of the previous graphing area. If you hold down Shift it will zoom in more, so you see 25% of the previous graphing area.

This will zoom out so you see 1.23 times as much as on the previous graphing area. If you hold down Shift it will zoom out more, so you see 4 times the previous graphing area.

Hold down the left mouse button while you select the area you want to fill the whole graphing area. Right click or press Esc to cancel the command.

This changes the y-axis to the same scale as the x-axis. It will make a circle look correctly instead of showing as an ellipse. The axes will stay equally scaled until disabled again.

Returns the axes settings to the same default settings used when creating a new coordinate system.

When selected the mouse pointer changes to a hand. You may now use the mouse to drag the coordinate system around. Select the menu item again, right click or press Esc to return to normal mode. As an alternative to this menu item, you may hold down the Shift key and drag the coordinate system around.

This will change the axes settings to show all parts of the selected graph element.

This will change the axes settings to show all parts of all the elements in the function list.

Calculates the distance along the path between two points on the selected graph.

Calculates the definite integral for a specified domain range. This is the same as the signed area between the graph and the x-axis.

This will evaluate the selected function for a given value. For standard functions f(x), f'(x) and f''(x) are evaluated. For parametric functions x(t), y(t), dx/dt, dy/dt and dy/dx are evaluated. For polar functions r(t), x(t), y(t), dr/dt and dy/dt are evaluated.

This dialog fills a table with a user-specified range of values and the result of evaluating the selected function for the values.

This dialog allows you to create an animation from the data in the coordinate system by changing an existing custom constant. This makes it easy to see what happens when the constant changes. The animation may be saved to a disk file.

This is a common place for plugins to put menu items that activates the plugin. The menu will not be shown if there are no plugins or the plugin system is not available.

Shows the contents and index of the help file.

Shows a list of functions and constants that may be used for plotting graphs.

This will show a list of frequently asked questions and their answers.

This will show some tips about using Graph in a more optimal way, and certain features of Graph you may not know about.

Shows the web site for Graph in your default web browser.

Shows the support forum for Graph in your default web browser.

Shows the web page that allows you to donate to the Graph project to support its development.

This will check if a new version of Graph is available. If there is a new version, you will be asked if you want to visit the web site of Graph to download the new version.

Shows version number, copyright and license information for Graph.

This allows you to move the coordinate system around. It is basically the same as selecting Zoom → Move system in the menu.

You can use the scroll wheel on the mouse to zoom in and out at the position of the cursor in the graphing area.

Hold down Ctrl while you use the arrow keys to move the view around in small step. If you also hold down Shift you can move in larger steps.

This zooms in on the x-axis in small steps. If you also hold down Shift you can zoom in larger steps.

This zooms out on the x-axis in small steps. If you also hold down Shift you can zoom in larger steps.

This zooms in on the y-axis in small steps. If you also hold down Shift you can zoom in larger steps.

This zooms out on the y-axis in small steps. If you also hold down Shift you can zoom in larger steps.
