Hi, I just noticed that this: >>> x = np.arange(10) >>> y = np.zeros(10) >>> y[5] = 1 >>> plt.bar(x, y) Will generate a big box for x = 5 with x 0:5 and 6: stripped, whereas this: >>> y += 0.000001 >>> plt.bar(x, y) Will generate a bar plot going from x = 0 to 9 with a bar at 5 as I was expecting. If I make a zeros vector with two discontiguous 1 values, then I also get the full x range, with two spikes. >>> y = np.zeros(10) >>> y[2] = 1 >>> y[5] = 1 >>> plt.bar(x, y) Is this expected? It certainly surprised me... Matthew
Which version of matplotlib are you running? I could have sworn this was fixed awhile ago. If I understand the problem correctly, essentially, the autoscalling was clipping empty patches out.

I'm embarrassed to say that I didn't look at my version, and now I do, it was 1.3.1, and you are quite right, 1.4.0 (and 1.4.2) fixes that. Thanks, and, sorry to write too quickly, Matthew
No problem!
