Apart from the common KDE menus described in the Menu chapter of the KDE Fundamentals documentation KmPlot has these application specific menu entries:
Displays the Constants dialog box. See the section called “Constants Configuration”.
The first three items in the menu are related to zooming.
The mouse wheel can also be used as a zoom control. To zoom in or out using the mouse, hold down the Ctrl key while you turn the mouse wheel. Each tick increases or decreases the zoom factor by the value defined in the KmPlot General settings.
- → (Ctrl+1)
This tool can be operator in two different manners. To zoom in on a point on the graph, click on it. To zoom in on a specific section of the graph, hold and drag the mouse to form a rectangle, which will be the new axes ranges when the mouse button is released.
- → (Ctrl+2)
The tool can also be used in two different manners. To zoom out and center on a point, click on that point. To fit the existing view into a rectangle, hold and drag the mouse to form that rectangle.
The scale will be adapted to trigonometric functions. This works both for radians and degrees.
Resets the view.
Displays the Coordinate System dialog box. See the section called “Coordinate System Configuration”.
Toggles the visibility of the slider dialog. In the dialog move a slider to change the parameter of the function plot connected to it.
Enable this on the Function tab and select one of the sliders to change the parameter value dynamically. The values vary from 0 (left) to 10 (right) by default, but can be changed in the slider dialog.
For a small tutorial see Using Sliders.
This menu contains some tools for the functions that can be useful:
Opens the Calculator dialog.
Select a graph and the values of the horizontal axis in the new dialog that appears. Calculates the integral and draws the area between the graph and the horizontal axis in the range of the selected values in the color of the graph.
Find the minimum value of the graph in a specified range.
Find the maximum value of the graph in a specified range.
