[Paraview] Bug in Color Scale
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 ___ ParaView mailing list ParaView@paraview.org http://www.paraview.org/mailman/listinfo/paraview
Re: [Paraview] Bug in Color Scale
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.

Re: [Paraview] Bug in Color Scale
Nope. I still can't replicate the problem. I downloaded the binary you
specify, loaded the data set you sent, and it set the range fine.
I notice from the image you sent that the color bar does not have the default
colors. Are you sure that you are actually using the version of ParaView you
downloaded as opposed to another version that might be in your path? Earlier
versions of ParaView used that rainbow scalar bar as a default. Either that or
you have been playing with color scale editor dialog box. In that case, you
may have accidently changed the range without realizing it.

range for the variable Rank in the information panel, we can see it is [3,3]
however the color displays only for range [0,1].

Re: [Paraview] Bug in Color Scale
Thank you Ken.
This is really strange then. I just downloaded the 32-bit version for Linux and
had the same problems. It sounds like a problem of my linux box.
By the way, I did change the color map to HSV earlier but I am sure I didn't
change anything else. And the new 32bit binary, I didn't do anything to it and
still get the [0,1] range. I guess I have to use some other machines to see
the problems.
Thank you for your quick response and I will keep you updated on my findings.

Re: [Paraview] Bug in Color Scale
Hi Shi, Ken, and all, A user of my reader reported exactly the same problem about the auto scaling on ParaView 3.5.0. He told me that after applying Rescale to Data Range to scalar attributes the range is always set to [0, 1], even though the data actually has a range of e.g. [87200, 87250]. He also provided me with one of the datasets that caused the problem but so far I am not able to reproduce the problem (tested with the CVS head on Windows and Linux 32bit). I kind of suspected an uninitialized variable somewhere and tried a valgrind test but it didn't tell me anything meaningful either. Hence, I'm interested in under what exact condition this problem would occur...? Did anyone else encounter the problem, and if so, is it 100% reproducible?

Re: [Paraview] Bug in Color Scale
I’m running out of things to suggest. The only problem I can think of (and this is a stretch) is that somewhere the range in the data array is being incorrectly set either by some rouge call to the information object or because the data in the array changes without the vtkDataArray object being aware of it. Does anyone else have any ideas? Berk? Utkarsh? What range of values is reported in the Information panel? Is it giving the correct range, or the range used in the color scale? -Ken On 11/28/08 7:46 AM, "Takuya OSHIMA" <[EMAIL PROTECTED]> wrote: Hi Shi, Ken, and all, A user of my reader reported exactly the same problem about the auto scaling on ParaView 3.5.0.

Re: [Paraview] Bug in Color Scale
OK. It sounds like the range is properly being computed, but the range is not
getting to the lookup table. If you are able to replicate the problem and
capable of running a debug version of ParaView in a debugger, you might be able
to narrow this down a bit more by setting a breakpoint at
pqPipelineRepresentation::resetLookupTableScalarRange().
Another possibility that occurred to me is that the rescale operation is
performed on the selected variable for the selected object in the pipeline
browser. Furthermore, all variables with the same name are synchronized to the
same color range. Thus, you could see this kind of behavior if you have the
wrong item selected in the pipeline browser.
