python中水平方向的物理拉伸图 [英] physically stretch plot in horizontal direction in python

问题描述

我想要一个简单的 x,y 图，用 matplotlib 创建，在 x 方向上物理拉伸.
目的是得到一个结果，如果我更容易检测信号中的特征.

I want a simple x,y plot created with matplotlib stretched physically in x-direction.
The intention is to get a result were it is easier for me to detect features in the signal.

所以我不想改变任何尺度、值或限制.只需更改输出文件中两个网格点之间的距离...

So I don't want to change any scales or values or limits. Just change the distance between two gridpoint in my output file...

我想在四个子图上这样做，之后应该具有相同的大小.

I want to do that on four subplots which should have the same size afterwards.

提前致谢...我已经尝试了几个小时，我想你们中的一个人可能会帮助我...

Thanks in advance... I tried for hours now and I think one of you could probably help me...

David Zwicker 已经在这个特殊情况下解决了我的问题，非常感谢，但总的来说......如果我像这段代码一样绘制 2 个子图:

David Zwicker already solved my problem in this special case, thanks a lot for that, but in general... If I plot 2 subplots like in this code:

fig = plt.figure()

ax1 = fig.add_subplot(1,2,1)

plot(u_av,z)

ax2 = fig.add_subplot(1,2,2)

plot(pgrd_av,z)

clf()

并且只想拉伸其中之一.我能做什么?

and want to stretch only one of them. What can I do?

推荐答案

您可以使用 plt.axes().例如:

You can directly add axes to the canvas at an arbitrary position with plt.axes(). For instance:

ax1 = plt.axes([0, 0, 3, 0.5])
ax2 = plt.axes([0, 0.6, 1, 1])
