如何在Matplotlib中的子图中添加标题?
问题描述：
我有一个包含许多子图的图形.
I have one figure which contains many subplots.
fig = plt.figure(num=None, figsize=(26, 12), dpi=80, facecolor='w', edgecolor='k')
fig.canvas.set_window_title('Window Title')
# Returns the Axes instance
ax = fig.add_subplot(311)
ax2 = fig.add_subplot(312)
ax3 = fig.add_subplot(313)
如何为子图添加标题?
fig.suptitle为所有图形添加标题，尽管ax.set_title()存在，但后者未向我的子图添加任何标题.
fig.suptitle adds a title to all graphs and although ax.set_title() exists, the latter does not add any title to my subplots.
谢谢您的帮助.
纠正了有关set_title()的错字.感谢Rutger Kassies
Corrected typo about set_title(). Thanks Rutger Kassies
答
ax.title.set_text('My Plot Title')似乎也可以.
fig = plt.figure()
ax1 = fig.add_subplot(221)
ax2 = fig.add_subplot(222)
ax3 = fig.add_subplot(223)
ax4 = fig.add_subplot(224)
ax1.title.set_text('First Plot')
ax2.title.set_text('Second Plot')
ax3.title.set_text('Third Plot')
ax4.title.set_text('Fourth Plot')
plt.show()
