Hello all,
I noticed some unusual behavior with specific combinations of axes.twinx and
pyplot.xticks. It seems that under certain conditions, the pyplot.xticks
command can cause an x offset of the plots. Here's a relatively short
example (as written, this works fine):
import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(-np.pi, np.pi, 1000)
fig = plt.figure()
ax1 = plt.axes()
ax1.plot(x, np.sin(x)+1)
plt.ylim(-1,2)
ax2 = ax1.twinx()
ax2.plot(x, np.sin(x) )
plt.ylim(-1,2)
plt.xlim(-np.pi, np.pi)
ts = np.linspace(-1, 3, 5)
#ts = np.linspace(-1, 4, 5)
plt.xticks( ts, ['%.2f'%i for i in ts] )
plt.show()
However, if the comment on the 'ts' array creation code is reversed, the
second plot appears offset from the original.
I realize it is idiotic to put ticks outside the axis range, but this caused
some problems when I inadvertently did it once (or more...).
I've tried this with Matplotlib 1.0.1/Python 2.6.6 (Python x,y) on Windows 7
and Matplotlib 1.0.1/Python 2.7.1 on Gentoo Linux.
Thanks
Ryan
