Dear all,

I am using D Fanning's colorbar routine.
But I have some questions about the corresponding value for each
color.

For example,

A=DIS(31,41)
DEVICE, DECOMPOSED=0
LOADCT, 5, NCOLORS=100
CONTOUR, A, POSITION=[0.15, 0.15, 0.95, 0.75], $
C_COLORS=INDGEN(100), NLEVELS=100, /FILLl

For min(A)=0 and max(A)=25, the color with index '0' should present
the value '0' and the color with index '99' should present the value
'25'.
Therefore, when I use the COLORBAR routine, the keywords RANGE should
be given.
COLORBAR, NCOLORS=100, POSITION=[0.15, 0.85, 0.95, 0.90],
RANGE=[min(A), max(A)]
Is it right?

If the minimum or maximum of the array has a floating-point value like
3.24, is the above command to add the colorbas still right?

Best regards,
Du Jian
