Rotate

Selecting Rotate sets XGobi in a three-variable plotting mode.  The
user can rotate the data about a fixed vertical or horizontal axis, or
about a floating oblique axis, which is controlled by mouse movements
on the screen.

To control the rotation with mouse movements, press and hold any mouse
button while the cursor is in the plotting window.  Now move the
cursor.  (Note that when the axis is fixed, movement is possible around
that axis.)

The lines appearing in the variable circles are proportional in length
and direction to the axes of the three participating variables, and the
small circle in the center of the variable circle indicates that a
variable is "last touched." See the help file for the variable
selection panel for more detail.

If there are fewer than three variables in the data, rotation is
disabled.

This button can be activated from the keyboard by typing r or R.
