Dear MPL gurus,
I've probably failed to RTFM properly.
I'm trying to produce error bars with horizontal lines at the top of the
vertical error bars to cap them. I've tried adjusting capsize on both
plt.bar and plt.errorbar, but have not had any success. I think I had
this working previously with 1.0.1, but can't remember for definite.
Matplotlib: 1.1.0
Python version: 2.7.2
IPython: 0.11
Windows XP 32 bit
Many thanks for any pointers, and apologies if I have missed an obvious
setting.
James
=== begin example code ===
import matplotlib.pyplot as plt
import numpy as np
plt.ion()
X = np.array([.5,1.5,2.5,3.5])
Y = np.array([1,2,3,4])
dY = np.array([.1,.2,.3,.4])
f = plt.figure()
ax = f.add_subplot(111)
A = plt.bar(X, Y, yerr=dY, ecolor='red', capsize=10)
A[0].set_facecolor('black')
A[1].set_facecolor('gray')
A[2].set_facecolor('black')
A[3].set_facecolor('gray')
ax.set_xlim([0.,4.8])
plt.show()
