在matplotlib中设置y轴限制 [英] setting y-axis limit in matplotlib

问题描述

我需要在matplotlib上设置y轴限制的帮助.这是我尝试失败的代码.

I need help with setting the limits of y-axis on matplotlib. Here is the code that I tried, unsuccessfully.

import matplotlib.pyplot as plt

plt.figure(1, figsize = (8.5,11))
plt.suptitle('plot title')
ax = []
aPlot = plt.subplot(321, axisbg = 'w', title = "Year 1")
ax.append(aPlot)
plt.plot(paramValues,plotDataPrice[0], color = '#340B8C', 
     marker = 'o', ms = 5, mfc = '#EB1717')
plt.xticks(paramValues)
plt.ylabel('Average Price')
plt.xlabel('Mark-up')
plt.grid(True)
plt.ylim((25,250))

利用此图的数据，我得到了20和200的y轴限制.但是，我希望限制为20和250.

With the data I have for this plot, I get y-axis limits of 20 and 200. However, I want the limits 20 and 250.

推荐答案

尝试一下.也适用于子图.

Try this . Works for subplots too .

axes = plt.gca()
axes.set_xlim([xmin,xmax])
axes.set_ylim([ymin,ymax])
