.LP
When the toggle button for "rescale" is selected, the user can change the
default settings for the minimum and maximum of the X, Y, and Z axes.  By
changing the settings the user can rescale the displayed plot.  Note that
the data is not changed, but the way the plot is presented in the
graphics workspace is changed.
.IP "Min and Max values for the plot window"
The user may specify the minimum and maximum values for the X, Y, and Z axes.
After the desired values are entered in the appropriate boxes, clicking on 
the action button, "CHANGE MAX MIN" will redraw the plot according to the
specified minimum and maximum values.  This may be useful when the user
would like to size the plot in a particular way.  If the window specified 
is too small for all plots in the window, plots may over-write the axes.
In any case, clicking on "RESET AXES" will restore the default window.
.IP "Major and Minor Tic Marks"
Specify the major interval between large tics by filling in the X, Y, and Z 
values under "Major Interval".  One large tic mark will be drawn after every 
"Major Interval" interval size.  The number of minor tics may be indicated 
here as well, by filling in the numbers under "Number of Minor Tics".  
Note that "Number of Minor Tics" refers to the number of minor tics BETWEEN 
each two major tics.  Initiate changes by clicking on "CHANGE INTERVAL".
