Re: [MPB-discuss] Data analysis question
Thanks for posting this very useful and informative page. Do you have any ideas on how we could get countour plots instead of smooth ones using h5utils? Something like this: http://www.mathworks.com/access/helpdesk/help/techdoc/ref/graphics_c11.gif I think I could make a colormap with duplicate entries, but the black lines between entries would be missing.

Re: [MPB-discuss] Data analysis question
Oops, Thanks. I have another question. When I choose colormap -c bluered -Z I can get the color in red only. Is there any possibility to make it all blue? Thanks for your time.

However, if you have data that goes from 0 to some positive value, then -Z bluered (with or without reversal) is probably not the best color scheme; it was designed for positive+negative data, whereas for single-signed data it only uses one color and hence only a small part of the dynamic range available from color. For all-nonnegative data like an energy density, I usually prefer the hot color scheme, which goes from black to red to yellow to white (like a heated black body). ___ mpb-discuss mailing list mpb-discuss@ab-initio.mit.edu http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/mpb-discuss -- The devil has put a penalty on all things we enjoy in life.

Re: [MPB-discuss] Data analysis question
Just one more question. If I use multiple color scheme, how do I print out the colorbar to indicate what color corresponding to what intensity scale? Thank you!
