Histogram within a colorbar [message #92216]

I am looking for an IDL mapping routine (or colorbar routine) which can create a histogram on the colorbar. The histogram should represents values plotted on the map.

HDFLook has something very similar as shown in the following image.

http://hdfeos.org/examples/images/hdflook/HDFLook_CMapWin.pn g

Any pointers will be helpful.

Thanks, Pawan

Here you go:

data = cgDemoData(7)
cgErase
cgColorbar, CTIndex=33, /Vertical, $
Position=[0.25, 0.15, 0.75, 0.85], /Right
cgHistoplot, data, /Rotate, /NoErase, $
Position=[0.25, 0.15, 0.75, 0.85], Color='Black', /Fill
END

Cheers,

David
