Hello developers, I'm seeing what appears to be a bug when plotting bars next to each other without edges. In pdf output, you can see that there is a tiny gap in between each bar, which renders as one pixel wide no matter how far I zoom in. It's also visible in interactive or png output:
http://www.dumpt.com/img/viewer.php?file=mc0wf07aksrzqs1h8j5k.png You can generate the above by running a slightly modified demo: ------------------------------------------- #!/usr/bin/env python # a stacked bar plot with errorbars import numpy as np import matplotlib.pyplot as plt N = 5 menMeans = (20, 35, 30, 35, 27) womenMeans = (25, 32, 34, 20, 25) menStd = (2, 3, 4, 1, 2) womenStd = (3, 5, 2, 3, 3) ind = np.arange(N) # the x locations for the groups width = 1.0 # CHANGED from 0.35 in the demo # CHANGED: adding linewidth=0 to these calls p1 = plt.bar(ind, menMeans, width, color='r', yerr=womenStd, linewidth=0) p2 = plt.bar(ind, womenMeans, width, color='y', linewidth=0, bottom=menMeans, yerr=menStd) plt.ylabel('Scores') plt.title('Scores by group and gender') plt.xticks(ind+width/2., ('G1', 'G2', 'G3', 'G4', 'G5') ) plt.yticks(np.arange(0,81,10)) plt.legend( (p1[0], p2[0]), ('Men', 'Women') ) plt.show() ------------------------------------------- Any thoughts on why there's always a tiny gap between bars?
