Hello,
okay, We can do this:
so each column is to become a thermogram (which I presume is just the
data from the column, displayed on its side, and made say 30 pixels tall
so it looks like a color scale (sounds like what a thermogram might be))
okay, first, I would transpose your array, so each thermogram is a row.
data = transpose(data)
image = intarr(600,600) ;define the image you will
; build
then build an image that will contain these thermograms. SOmething like
the following: (assuming your data are integers less then 255)
therm1 = rebin(data(*,0),100,40) ;assuming a multiple of rows of
; data is 100
This took your row, and stretched (rebined) it into a 100x40 array (AN
IMAGE! Cool!)
now put this into your image you are building:
image(20,500) = therm1
and so on for each of the thermograms. PLacing each in a different
position of the image array.

same idea exacly for the color index, just label it with XYouts.
SOmething in my head says there in a colorIndex routine in the user
library, but not sure.

Also, you could just plot each of these rows of data (each thermogram)
and use !P.Multi to display all the plots in the fashion you described
above.
