[Wien] Reg: charge density plots

[Swetarekha Ram]

Dear users,

  I have small doubt in the charge density plots.

At the time of doing the charge density plots through Xcrysden it will ask
for the lowest rendered value and highest rendered value.
According to this we will get our color code bar.


Can any one tell me what actually it mean ?

What information we will get from this.

Thanking You.
