Hello, Josh,

Yes, I did not set the range of the color at the trajectory tab.

It works after I modify the max and min value there.

Thank you!

Geng

Hi Geng,

It sounds like what you want to do it control the color on a representation
basis. If you modify the colorscale range for each representation (its under
the trajectory tab of the graphical representations window, not the draw
style tab), the colors should be consistent for each representation. Then it
looks like you would set the same minimum and maximum scale values in the
color scale bar extension, and be happy.

Hello, everyone,
(I have sent this email yesterday, but I don't see it on the list. The older
email may be already filtered out by system, so I have re-send this email
again) I encounter a problem for generating color bar in VMD.(using the
tools in the extenstion->visualization->color scale bar) The cluster is
imported by LAMMPS dump format, and atoms have charge attribute. So I want
to color the atoms according to their charges. Two different modes are
available in VMD:
1) In the auto mode, the color bar shows the right relation between colors
and charges. But there is no way to adjust the maximum and minimum values in
the color bar axis. So If I have different structures, they will have
inconsistent color bar legends.
2) If I turn off the auto mode, I can adjust the maximum value and minimum
value, but the colors on the atoms are not altered accordingly. I.E. the
color bar legend is wrong and scales on color bar axis is arbitrary.
So How I can I make sure the color on atoms are changed accordingly when I
modify the range of values in the color bar axis?
Thank you very much!
