我能想到四种方法,都很丑。我不知道是否有任何自动设置这些东西的方法。
四种丑陋的方式是:
ax.set_title()
1)使用(在您的情况下ax1
和)将标题设置为每个组中的“顶部”轴对象ax4
。它对左组效果很好,但对右组来说很糟糕......
2) 用 设置一个标题fig.suptitle
,但在标题内留出很多空格,并使用horizontalalignment='center'
.
3)为每个标题手动设置一个文本对象...(不在下面的示例中,但只需查看matplotlib.text)
4)创建鬼斧,隐藏它们上的所有东西,然后用它们来设置它们的标题......
下面是一些示例代码
import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec
fig = plt.figure()
gs1 = gridspec.GridSpec(3, 3)
gs1.update(left=0.05, right=0.48, wspace=0.05)
ax1 = fig.add_subplot(gs1[:-1, :])
ax2 = fig.add_subplot(gs1[-1, :-1])
ax3 = fig.add_subplot(gs1[-1, -1])
ax1.set_title('Left group title') # Alternative 1)
gs2 = gridspec.GridSpec(3, 3)
gs2.update(left=0.55, right=0.98, hspace=0.05)
ax4 = fig.add_subplot(gs2[:, :-1])
ax5 = fig.add_subplot(gs2[:-1, -1])
ax6 = fig.add_subplot(gs2[-1, -1])
ax4.set_title('Right group title') # Alternative 1)
# Alternative 2. Note the many white-spaces
fig.suptitle('figure title left figure title right', horizontalalignment='center')
# Alternative 4)
rect_left = 0, 0, 0.5, 0.8 # lower, left, width, height (I use a lower height than 1.0, to place the title more visible)
rect_right = 0.5, 0, 0.5, 0.8
ax_left = fig.add_axes(rect_left)
ax_right = fig.add_axes(rect_right)
ax_left.set_xticks([])
ax_left.set_yticks([])
ax_left.spines['right'].set_visible(False)
ax_left.spines['top'].set_visible(False)
ax_left.spines['bottom'].set_visible(False)
ax_left.spines['left'].set_visible(False)
ax_left.set_axis_bgcolor('none')
ax_right.set_xticks([])
ax_right.set_yticks([])
ax_right.spines['right'].set_visible(False)
ax_right.spines['top'].set_visible(False)
ax_right.spines['bottom'].set_visible(False)
ax_right.spines['left'].set_visible(False)
ax_right.set_axis_bgcolor('none')
ax_left.set_title('Ghost left title')
ax_right.set_title('Ghost right title')
plt.show()
