在Matplotlib中的x和基线x位置之间填充 [英] Fill between x and baseline x position in Matplotlib

问题描述

我正在寻找一种在matplotlib中使用fill_between在x1和x2之间进行着色的方法，而不是y1和y2.

I'm looking for a way to use fill_between in matplotlib to shade between x1 and x2 as opposed to y1 and y2.

我有一系列对数图，Y轴上的深度，x轴上的是测量变量，并且希望在绘制线的左侧或右侧(而不是上方或下方)着色.

I have a series of log plots, with depth on the Y axis, and the measured variable on the x axis and would like to shade to the left or right, as opposed to above or below, of the plotted line.

我相信这可以通过fill_between实现，但不能使其正常工作.

I'm sure this should be possible with fill_between but cant make it work.

例如:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec


gs = gridspec.GridSpec(3, 3)
ax1 = plt.subplot(gs[0, :])
ax2 = plt.subplot(gs[1:, 1])

y=np.random.uniform(0,1,30)
x=np.arange(30)

ax1.set_ylabel('Plot 1')
ax1.plot(x,y)
ax1.fill_between(x,y,0.5,where=y>0.5,interpolate=True)

ax2.set_ylabel('Plot 2')
ax2.plot(y,x)
ax2.set_ylim(30,0)

plt.show()

我已经附上了这样产生的图像: 本质上我想在图2的位置上绘制类似图1的图形

I have attached an image of what this produces: Essentially i want to plot something like plot 1 in the plot 2 position

谢谢您的建议

推荐答案

，您可以使用 fill_betweenx

you can use fill_betweenx

ax2.fill_betweenx(y,x, x2=0.5, where=x>0.5,interpolate=True)
