Taking the image size to (30,30) made all the segments appear, but their thickness was still not uniform. Using some sort of smoothing helped, but it still not displaying what the matrix was specified as: a set of blocks, somewhat resembling a line, all of which are the same color and thickness. Can I have matplotlib show the matrix as I have specified it? Or is that too naive (on my part)? ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
