[Paraview] Bug in Color Scale

[Moreland, Kenneth]

Shi,

I have not run into this, nor have I heard of anyone else who has.  Could you tell us more about your data or, better yet, send us an example?

One thing that has changed with the rescale range feature recently is that the range is now computed based on the values that appear throughout an entire volume, not just what appears on the surface.  Thus, if you are rendering a volume of data with 1 in the middle but with the surface only having up to 0.01, the range is still going to be up to 1.  Check the ranges in the Information panel.  The scalar bar range should agree with that.  If you don't know where the upper values are located, try using the threshold filter to find them.

Hi there,

I just upgraded my paraview from 3.10 to 3.40. Immediately I found that the same data was not colored correctly with the new version. It turned out that in the Display Tab, Rescale to Data Range button actually does nothing. If I clicked on Edit Color Map.., I found that the maximum of data range is always 1 (minimum always 0), no matter what the real range is. I can of course uncheck Automatically Rescale to Fit Data Range, and set the range using Rescale Range button by hand. However, I think this is not what it is supposed to be.  I tried both the Linux-64bit binary found online and my own build on an ubuntu box and they have the same problem.  Please let me know if it is indeed a bug or just something I didn't get right. Thanks a lot.

Thanks a lot.
Shi
