## [Matplotlib-users] wrong number of logarithmic minor ticks

 [Matplotlib-users] wrong number of logarithmic minor ticks From: Steve Ward - 2011-05-20 03:38:19 ```>From running the code below, I see only 8 subticks between the major ticks. But the documentation ; says there should be 10. I'm using matplotlib version 0.99.3. #---------------------------- import matplotlib.pyplot as plt import numpy as np y = range(1, 4) x = np.power(10, y) plt.gca().set_xscale('log', basex=10, subsx=[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]) plt.gca().plot(x, y) plt.show() #---------------------------- However, even if 10 are being drawn, I think there would only be 9 subticks between the major ticks because the first subtick is on a major tick. Am I wrong? Steve ```

The suggestion of doing [0, 1, 2, 3, ...] for subsx has two problems. First, the subtick at 0 will never show up! Second, the subtick for 1 is also a major tick. While this isn't technically wrong, (maybe the major ticks get turned off or something...), it is a poor example and I will fix it. Thank you for pointing it out. Ben Root ```
