Hi, I am testing the new vtkBlockColors feature in the latest Paraview (I am using 0a4ad038370beb6d30f51f43e32555b3adcea123), as introduced in the blog post: http://www.kitware.com/blog/home/post/859
Currently the legend shows colors with numbers 0-6. However, many times the sidesets in an ExodusII file are not labeled like that. I am attaching a screenshot with an example. As you can see, both the Properties as well as Multi-block Inspector shows the correct side set ID numbers (1, 5, 10, 15), but the vtkBlockColors legend shows numbers 0-6. Note that if I color by vtkCompositeIndex, the legend shows the correct side set ID, but the problem is that it's a continuous legend, and the colors are close to each other, so it's hard (essentially impossible) to tell what the ID is from the color. I understand the user case when there is thousands of blocks. But I think there is also a use case when there is relatively few (~10) boundary conditions, and you just want to see them all at once using a legend, so that you can take a screenshot and send it to somebody. Maybe there can be some check-box that would switch the two modes of the legend. Currently the best way seems to be to use vtkBlockColors, and then send a screenshot that includes the Multi-block Inspector window, which also shows the colors and proper IDs. There is also the issue of Block ID versus Side Set ID (as a side set can have the same id as a block set), I usually turn one or the other off in Multi-block Inspector, then they are not mixed. Let me know what you think. Ondrej
