我需要繪製條形圖不對稱誤差棒...matplotlib酒吧不對稱誤差條
的matplotlib.pyplot.bar函數的文檔說:
Detail: xerr and yerr are passed directly to errorbar(), so they can also have shape 2xN for independent specification of lower and upper errors.
但是,我可以不給一個2×N個排列到yerr ...
import numpy as np
import matplotlib.pyplot as plt
plt.bar(xrange(5), [2,5,3,4,7], yerr=[[1,4,2,3,6],[4,10,6,8,14]]) #DO NOT work!
並告訴我下面的錯誤:
Traceback (most recent call last):
File "bar_stacked.py", line 9, in <module>
plt.bar(xrange(5), [2,5,3,4,7], yerr=[[1,4,2,3,6],[4,10,6,8,14]])
File "/usr/lib/pymodules/python2.7/matplotlib/pyplot.py", line 1742, in bar
ret = ax.bar(left, height, width, bottom, color, edgecolor, linewidth, yerr, xerr, ecolor, capsize, align, orientation, log, **kwargs)
File "/usr/lib/pymodules/python2.7/matplotlib/axes.py", line 4253, in bar
"incompatible sizes: bar() argument 'yerr' must be len(%s) or scalar" % nbars)
ValueError: incompatible sizes: bar() argument 'yerr' must be len(5) or scalar
但是,不是此函數:
import numpy as np
import matplotlib.pyplot as plt
plt.errorbar(xrange(5), [2,5,3,4,7], yerr=[[1,4,2,3,6],[4,10,6,8,14]])
工作正常。
matplotlib.pyplot.bar不再支持yerr的2xN數組嗎? 如果答案是肯定的......我如何繪製一個帶有不對稱誤差線的條形圖?
謝謝你的時間!
我有0.99.3版本...我gona編譯1.1.1,非常感謝! – Geparada
已解決!謝謝。 – Geparada
