Hi Geng,


I don't believe that the minimum and maximum values for the color bar are linked to those in your atom representations.


Look under the "Trajectory" tab in the Representations window for the charge representation and you can set the minimum and maximum color values there to match the ones you set for the color bar.


Hope this helps,

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!
