how to midify cbar

[sh zhou]

Dear All,

In attachment there are two shaded contour plots, I want to compare them,
but the color bar, at the bottom of each plot, not the same. In a plot the
color bar's mark range from "288" to "306", the another one is range from
"286"to "296", I tried to modify "cbar.gs", but it is too difficult to me,
can you tell me how to set the range to be the same?

   Thank you.

Sincerely.
