[Paraview] Lock Data Range for multiple attributes

Fri Oct 7 09:32:58 EDT 2016

This was already reported as a bug (see the attached email). Perhaps this is a good opportunity for a little reminder ;-)

Mathieu

Thank you so much!
It seems that I can have other color values in between the min/max (so I don't have to remove all the dots), but the scale must contain the min/max contained in the attribute data as limits. I now understand what you meant in your previous e-mail...
Yes, the color bar is not optimal, but right now I care more for a consistent coloring of all objects.

Maybe the Lock Data Range function could be made to work in this scenario as well in a future PV version. That would still be very helpful :).

Thanks again
Venke
