How to add an empty graph

You can add a 2D/3D Graph from context menus:

Insert > Plot > 2D / 3D

add new graph

- A 2D Graph can be added directly typing '@'

Now an empty graph will be added:

empty graphs

Plot equations

Variables to plot equations must be:

  • 'x' for 2D graphs

  • 'x' and/or 'y' for 3D graphs

You have multiple ways to plot equations:

Directly from the plot window

single equation - direct input

Indirectly, building your equation outside the plot window

single equation - indirect input

Plot Matrices

You can plot figures from matrices (directly or indirectly):

single equation - matrices

Special Plots

Multiple plots

You can plot multiple equations/matrices on the same graph using the 'Multiple values' item


Zooming is done with the zoom tool. If you roll your mouse wheel it zooms both axes together. If you hold 'control' at the same time it just zooms the vertical axis, and if you use 'shift' and the mouse wheel it zooms the horizontal axis.

Plot more than one curve by using the Equation systems button on the Functions toolbox.
