Matplotlib imshow() stretch to "fit width"
提问by ajwood
I've got an image, and a measure associated with each column of its pixels. I'm using pyplotto create a figure with the image on top, and a plot of the column measurements below. I'm using something like this:
我有一个图像，以及与其像素的每一列相关联的度量。我正在使用pyplot顶部的图像创建一个图形，以及下面的列测量图。我正在使用这样的东西：
import numpy as np
import matplotlib.pyplot as plt
A = np.random.rand(34*52).reshape(34,52)
means = np.average(A,axis=0)
plt.figure()
plt.subplot(2,1,1)
plt.imshow(A, interpolation='nearest' )
plt.subplot(2,1,2)
plt.plot(means)
plt.show()
How can I stretch the image's width to the match that of the plots. That way, when looking at the measurements in the plot, the souce pixels will be in a column directly above it.
如何拉伸图像的宽度以匹配绘图的宽度。这样，当查看图中的测量值时，源像素将位于其正上方的列中。

Turns out that it's as simple as giving aspect='auto'to the imshowcall.
事实证明，它是那样简单给aspect='auto'的imshow电话。
plt.imshow(A, interpolation='nearest', aspect='auto')
