Image activities mapped to colorbar [message #11888]

Hi folks,

I have some data sets of SPECT images that I want to display in a
window. For example:

IDL> for i=0,30 do tvscl, ImageSeq(*,*,i), i

where "ImageSeq" is a 3D FLTARR which contains a particular slice of the
brain. Since the images represent the activities in the brain at different
time, if I display the images with the above way, all of the images would
be scaled to their own maxima. What I want to do is to display the images
according to their activities and mapped the activities to a color bar so
that the first image frame may appear black while the last frame may
appear grey/white with background still black (assume that I use B/W for
display). How can I do that ??

Any hints would be greatly appreciated !!

KP.
