Hi I am attaching a contour picture-I have scaled it from 0 to 0.5. 0.5 is white in the legend but on the contour i cannot see any white. It colored them all by black. What is happening here, any one please help??

As a guess, your surface is ranging from about 0.0 to about 0.1. Thus, when your color legend ranges from 0.0 to 0.5, you get very dark colors. There are four icons on the middle left that have a green horizontal arrow in them. The furthest right will set the color legend min and max for what is VISIBLE. The left one will set the color legend min and max for the total range, including for cell data that is internal. Does that help?

Hi, thanks. I have few different simulations and i want to represent them on the same scale. Thats why i am trying to scale it within a similar range. But i i scale it on the same range then although it is showing white on the legend there is nothing white on the contour.

Which totally makes sense if you don’t have data that goes from 0 to 0.5, right? If I have an iron bar that runs from 0 to 100 degrees (black to white) next to a bar that goes 0 to 20 degrees, you wouldn’t expect the 0 to 20 degree bar to also go black to white…
One thing you may want to try is coloring using logging. View/ Color Map Editor/ Use Log Scale When Mapping To Colors.

Yes u are right. Then i have to use a few legends for individual contours by their side or try the log coloring as you say. thanks.

Changing min and max is kind of a bad thing to do, because it’s easy to get confused. However, if you do, you can always split screen. Those are the icons on the upper right of the view. Then, the icon just to the left of the green arrow icons will allow yo to have a different min and max in each view. Otherwise they are linked (as they should be), and changing one will change the other.

Does it depend on the specific colorbar i am using in Paraview? I am using grayscale and keeping the ReScale to data range option on. So it shows black to white on the legend, but some values seem to be not white on the contour.
