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,
Robin
