In this case, the array of tick locations is actually [-1, 0, 1, 2, 3, 4], so what you need to do is provide labels to match those locations. Try this: alpha = ['', 'ABC', 'DEF', 'GHI', 'JKL', ''] Eric > > the thing is that I don't know why, the label 'ABC' doesn't appear, leaving > the > last cell without label. > I would like to known how do I properly label my heatmap, when I use set_ticks > the figure decrease size and the colorbar stay bigger than the figure. > If someone would have a clue how to modify my script in a way to appear the > 'ABC' I would be grateful :) > ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ Matplotlib-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/matplotlib-users
