如何在matplotlib中限制y轴高度? [英] How do you limit the y-axis height in matplotlib?

问题描述

你如何限制matplotlib图中y轴的高度?我试图既显示x轴，又减小该1D图的图形高度.

How do you limit the height of the y-axis in matplotlib figure? I am trying to both display the x axis, and reduce the height of the figure for this 1D plot.

我尝试过设置刻度、图形大小、tight_layout、边距等，但都没有成功.

I have tried setting ticks, figure sizes, tight_layout, margin, etc. with no luck.

此外，无论我选择什么限制，更改 ylimits 只会跨越整个图形高度.

Also, changing the ylimits just spans the full figure height no matter what limits I choose.

import numpy as np
import matplotlib.pyplot as plot
from matplotlib import rcParams

x = np.array([3500])
y = np.array([0])

rcParams['toolbar'] = 'None'

plot.figure(num=None, figsize=(4, 1), dpi=80, facecolor='w')
plot.axes(frameon=False)
plot.yticks([0])
plot.xlim(0, 6000)
plot.ylim(-0.1, 0.1)
plot.plot(x, y, 'x', markersize=10)

plot.show()

推荐答案

只需将 figsize 更改为 (4, 0.3)，我得到的东西或多或少看起来像您想要的输出(除了顶部有刻度，但也可以删除):

Simply changing figsize to (4, 0.3), I get something that more or less looks like your desired output (except with ticks at the top as well, but those can also be removed):
