[Matplotlib-users] histogram plots color range

Hello , I have a two dimensional array, 40X20(rowsXcolumns). Each of the 40 rows themselves hold values of the bins of a distribution (which is not always normal, can expect a bimodal curve as well) It is little difficult to explain to I actually created a sample figure: http://www.flickr.com/p

Hi I have a array, M, which is (4Nx4M), and an array (image), im, which is NxM. I can currently plot the matrix as a 2d image using imshow using: import matplotlib.pyplot as plt from matplotlib import cm # some code for reading in the matrix cmap = cm.get_cmap('jet', 256) imM = plt.imshow(M, cm
