When right-clicking on a plot function or a single-point parametric plot function a popup menu will appear. In the menu there are seven items available:
Hides the selected graph. Other plots of the graph's function will still be shown.
Removes the function. All its graphs will disappear.
Shows the editor dialog for the selected function.
For plot functions the following four items are also available:
Opens a dialog in which you can find the y-value corresponding to a specific x-value. The selected graph will be highlighted in the dialog. Enter an x value in the X box, and click on (or press Enter). The corresponding y value will be shown under Y.
Find the minimum value of the graph in a specified range. The selected graph will be highlighted in the dialog that appears. Enter the lower and upper boundaries of the region in which you want to search for a minimum, and click . The x and y values at the minimum will be shown.
This is the same as above, but finds maximum values instead of minima.
Draws the area between the graph and the x-axis. The selected graph will be highlighted in the new dialog that appears. For more information on the Search for Area Under Graph-feature, see the section called “The Menu”.
