Sigh... Going back to bed. Let's try this again:

data = cgScaleVector(cgDemoData(7), -5, 70)
Loadct, 0 ; Reset colors
cgLoadct, 1, NColors=10, Clip=[100,250]
cgLoadCt, 3, NColors=140, Bottom=11, /Reverse
TVLCT, cgColor('white', /Triple), 10
cgImage, BytScl(data, Top=150), Position=[0.125, 0.1, 0.925, 0.75]
cgColorbar, NColors=151, Range=[-5, 70]
cIndex
END

Cheers,

David
