Hi,
I'd like to generate a colormap index based on an array of levels using an
existing colormap (Spectral).
However, Id like the cmap index to start at the 0.3 value of the Spectral
scale (orange/yellow area) instead of starting at the '0' scale value (red
area), and then

Thanks JJ, this works fairly well.
I was wondering if the following would also be possible: at start up, draw all
the minute bars in an invisible background, and on each update only display a
subset of the background.

of the last 24 hours worth of data.
I can make the plots but

I can make the plots but can not figure how to get past show().

Eric,
Thanks, that worked...
I have a separate question about colormaps...
I'd also like to try creating my own custom colormap by modifying an
existing cmap, inserting/removing colors by changing the values in the rgb
dictionary...
How do I retrieve the actual rgb dictionary associated with,
Can someone please recommend a (semi) automatic way to create the rgb
dictionaries needed for colormap creation?
Basically, I have a 'general' idea of how I want my colors ordered, but Im
finding it difficult to create the smooth transitions by manually editing
the rgb dictionary for my custom

Jeff,
Ok, so this is what I was trying to achieve...
c=['#6C9F7B','#783F68','#F4F4F2','#22F322','#F3F322','#F3']
mycm=mpl.colors.LinearSegmentedColormap.from_list('mycm',c)
plt.imshow(rand(10,10),cmap=mycm,interpolation='nearest')
colorbar()
plt.show()
That was the initial goal; being able
