slider for z-axis mapping

["Walter, Chris G" <chris.g.walter@xxxxxxxxxx>]

Im looking for a an easy way to add a slider for
changing the "gain" or amplitude scaling on an series
of radiance images that are being animated.
I would like some interactine way to scale the z-axis or radiance
values being displayed because they cycle through a large dynamic
range from start to finish.

I messed around with the labeledColorWidget, but could not see how it could
be used to select the color map on the fly.


Thanks in advance.
