how to change z-value in a specific region in intensity graph

[GiangV]

Hi all!

I have an intensity graph and I want to mark a specific region which is dark and then change the z-value(autoscale) so I can see what's in  this region, of course the rest of the intensity graph will be very bright but it's not a problem.  How do I do that?

Thanks in advance

Easiest method is to change the z scale, unselect autocscale z and rescale the max and min z to the max and minimum region of interest.  This can be easily automated, by using the roi as a subset of the input array and then get max min of the subset and feed it to the z-scale property max min.
