Boxplot和Scatter Plot Python

Question

我正在尝试使用matplotlib在python上绘制相同图中的boxplot和散点图。

这是我的代码：

# plotting results
plt.figure(figsize = (10,8))
plt.scatter(dfplot['Date'].tolist(), dfplot['Zplume_obv'].tolist(), color = 'red')
plt.boxplot(l2, patch_artist = True)
plt.xticks(range(7), [0]+df2['Date'].tolist())

# format the plot
plt.ylabel('Plume Height')
plt.title('Observed vs Test Plume Heights')
plt.gcf().autofmt_xdate()
obser = mpatches.Patch(color = 'red', label = 'Measured Data')
test = mpatches.Patch(color = 'blue', label = 'test Data')
plt.legend(handles = [obser, test])
plt.show()
plt.close()

我的代码很好但结果只是像这样的箱形图：

正如您所见，散点图无处可寻。任何修复？

Answer 1

不知道数据很难准确理解发生了什么。 我的猜测是：matplotlib根据您给出的顺序绘制艺术家，以便在boxplot之上获得scatter。如果你的大多数圈子都在盒子图下面，你就看不到了。外面的圆圈，如第一和第五个元素，是可见的。

您有两种选择：

1. 转换来电 [编辑这不起作用]
2. 使用zorder关键字作为例如在此example

修改

我很想知道为什么我的答案被低估了，因为它是正确的。

使用python 3.5下的matplotlib v 2.0.2，下面的示例将散点图放在boxplot的顶部:(部分从here复制）：

import matplotlib.pyplot as plt
import numpy as np

spread = np.random.rand(50) * 100
center = np.ones(25) * 50
flier_high = np.random.rand(10) * 100 + 100
flier_low = np.random.rand(10) * -100
data = np.concatenate((spread, center, flier_high, flier_low), 0)

plt.scatter([0.9, 1], [0, 50], c='r', zorder=10)
plt.boxplot(data, patch_artist = True)

这会在箱线图顶部生成散点图：

如果我将zorder=11添加到boxplot调用或将其从plt.scatter中移除，则[1, 50]中的红点会正确显示在框后面。
