Summary0008078: Unordered Color Maps
DescriptionSome data values do not have any logical order associated with them. For example, block ids and process ids have identifiers that distinguish them, but there is no real meaning between the relationship of each pair. Thus, it makes little sense to use our standard linear color maps. A much better approach would be to map individual colors to values and show these colors as blocks in the color bar. VisIt demonstrates this quite nicely (although the colors they use aren't perfect).

Yumin, please advise on how to go about fixing this and how much work it entails.

Showing the colors as blocks in the color bar is not complicated, and can be achieved mainly by modifying vtkPVScalarbarActor::BuildScalarBarTexture(). The thing that needs some thinking is how to display ticks and labels (linear vs log) in this case. Anyway, it may take a couple of days of work, and the changes should be fairly isolated in only a couple of classes, I think.
