Case Profile

This button initiates a popup window which will contain a plot
called the case profile.  Each time you identify a new point in
the main plotting window, the case profile window displays a
plot showing the series of values of each variable for that
case.

The case profile is drawn using the color and glyph of the point
identified in the main plotting window.

Cases with "sticky" labels are drawn using dotted lines, while
the current case is drawn using a solid line.

You can choose independently whether to have the points 
and the lines drawn in the case profile window.
