Check out the gallery; several examples there use a colorbar. http://matplotlib.sourceforge.net/gallery.html Then look for relevant sections in the docs, such as http://matplotlib.sourceforge.net/users/image_tutorial.html http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.colorbar etc. Eric > > import scipy,pylab > import matplotlib.cm <http://matplotlib.cm> as cm # colormaps > import matplotlib.colors as col # colormaps > > dat = scipy.array([[1,2,3,4],[5,6,7,8]]) > > fig = pylab.figure() > ax = pylab.gca() > ax.set_title('the title') > > ## here's chaos :) > #cmap = cm.get_cmap('rainbow', 20) # 10 discrete colors > #ax.imshow(dat, cmap=cmap, interpolation='nearest') > #fig.colorbar(dat) > #min,max = dat.min(),dat.max() > > ax.imshow(dat,interpolation='nearest') > pylab.show() > > Thanks a lot in advance, > Daniel > > > > ------------------------------------------------------------------------------ > The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: > Pinpoint memory and threading errors before they happen. > Find and fix more than 250 security defects in the development cycle. > Locate bottlenecks in serial and parallel code that limit performance. > http://p.sf.net/sfu/intel-dev2devfeb > > > > _______________________________________________ > Matplotlib-users mailing list > Matplotlib-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/matplotlib-users ------------------------------------------------------------------------------ The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.
