[visad] Display Range value on screen

Hello all,

My file structure is like: ( Lat , Lon ) --> Temp.
And I map Temp. value to Display.RGB
I get a 2D image on screen.

When I click on screen, I got Lat and Lon values printed, but I also want
the range value, that is "Temp." to be displayed on screen on a mouse click.
The image must be in 2D only.
