Zooming in 3D

The easiest way to zoom in and out of a 3D graph is to use the mouse wheel. Scrolling up on the wheel zooms in, and scrolling down zooms out.

If your mouse does not have a wheel, you can either use the '+' and '-' keys or right click on the graph and choose zoom in or zoom out.

The amount that GraphCalc zooms is proportional to the size of the graph and the distance from the origin.

To slow down zooming you can hold down the Shift key while you zoom. Note, this will only work if you are using the mouse wheel method.
