Sliders and string.
\bold

These sliders and string gadgets control the rotation vectors of the graph.
  The first line of gadget contain (from the right);identifier of the
rotation axis, 'X' in this case, a scroll gadget wich select the value of
the 'X' rotation and a string gadget which permits to enter the value
numerically. The two other line do the same thing but for the 'Y' and 'Z'
axes. Modification of any of the gadget updates the Preview window
automatically.
  The slider gadget named "Perspective", as his name implies,
will change the perspective value; the more the cursor is sled to the left,
the more the graph will look "deformed" (like a camera with a fish-eye len), to
opposite , sliding it to the right will yield in a more orthogonal-looking
graph. This effect is just for visualisation, so it, it will not be saved
in the "3D Geo" format.

There is also a cluster of 10 buttons at left that are ARexx controlled;
an ARexx script can be assigned to them that will be executed when pressed.
The default script given with JcGraph assign some values to these button.
