.IP Grid
To turn the grid ON, click on the action button next to "Grid".
The plot will be redrawn with grid marks at the major tic intervals.  
No change in the workspace viewport will occur.
.IP Box
To select a closed box for the axes, click on the action button next to "Box",
changing the button from OFF to ON. The plot will be redrawn with a closed box 
connecting the X and Z axes and the Y and Z axes.  The default is no box.
.IP Plot Legend
To turn the legend OFF, click on the action button next to "Plot Legend". 
The plot will be redrawn without a legend.
NOTE: when the legend is turned off, the workspace plot area will be re-sized
to use the extra space that would otherwise have been used for the legend.
Thus, when the legend is OFF, the plot(s) will be displayed using a much larger
portion of the workspace, and thus may be easier for some users to read.  When
the legend is turned back ON, the viewport must again shrink in size in order
to make room for the legend.
.IP "Auto Scale"
Clicking the action button next to "Auto Scale" will turn auto scale ON.  This
action will redraw the plot with the scale automatically calculated from the
plot data.  The minimum and maximum values of the plot data will determine
the scaling of the plot.
.IP Axes
Similar to the grid option, the "AXES" action button allows the user
to turn the axes lines on or off.
.IP "Numerical Labels"
To turn the numerical labels OFF, click on the action button next to
"Numerical Labels".  This will turn the numerical labels OFF along each axis.
.IP "Axes/Title Labels"
To turn the axes and title labels OFF, click on the action button next to
"Axes/Title Labels".  This will turn the labels OFF along each axis. Click
again to make them visible.
