Plot旁边的文字

Question

# Create a figure instance
fig = plt.figure(1, figsize=(9, 6))

# Create an axes instance
ax = fig.add_subplot(111)

## add patch_artist=True option to ax.boxplot() 
## to get fill color
bp = ax.boxplot(data_to_plot, patch_artist=True)

## change outline color, fill color and linewidth of the boxes
for box in bp['boxes']:
    # change outline color
    box.set( color='#7570b3', linewidth=2)
    # change fill color
    box.set( facecolor = '#1b9e77' )

## change color and linewidth of the whiskers
for whisker in bp['whiskers']:
    whisker.set(color='#7570b3', linewidth=2)

## change color and linewidth of the caps
for cap in bp['caps']:
    cap.set(color='#7570b3', linewidth=2)

## change color and linewidth of the medians
for median in bp['medians']:
    median.set(color='#b2df8a', linewidth=2)

## change the style of fliers and their fill
for flier in bp['fliers']:
    flier.set(marker='o', color='#e7298a', alpha=0.5)

我创建了一个像这样的盒子图。 如何在绘图旁边添加文本。不是在情节上，而是旁边的情节？ 这可能。

每个x-tick都有一个归属于它的特定名称，但是要在每个x上直接写它。因此，我需要一个单独的文本“框”，我可以在其中描述每个x。

自己测试代码：

## Create data
np.random.seed(10)
collectn_1 = np.random.normal(100, 10, 200)
collectn_2 = np.random.normal(80, 30, 200)
collectn_3 = np.random.normal(90, 20, 200)
collectn_4 = np.random.normal(70, 25, 200)

## combine these different collections into a list    
data_to_plot = [collectn_1, collectn_2, collectn_3, collectn_4]
