Unordered Color Maps
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Some 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).
