GraphCalc has fairly extensive built in help files. For details about
features or usage, select "Help..." on the Help menu or press "F1"
There are three tabs above the graph area which correspond to the three main features of
GraphCalc.
The leftmost tab is "Output" which is the display area for the scientific
(non-graphing) calculator.
The middle "Graph1" tab is the 2D graph screen
The right "3D Graph" tab is the 3D graphing screen |
3D Graph Screen

3D graph tab screen
Enter functions by selecting the, "3D graph" menu, then "Equations..."
menu item. A dialog box will appear which allows you to enter the desired equation to graph in
the z=f(x,y) format.

Additional features:
There are additional features on the "Tools" menu:
-- an equation solver to find the roots of a function
-- scripts which find areas of circles, etc.
On other menus here are also options to set number base, line colors, etc
| Missing functions and bugs:
In 3D mode, like all 3D navitation controls, it is very hard to rotate the image how you wish.
