python: 多分割小提琴图叠加

Question

我有一组样本可以用小提琴图来说明。这是 plotly.

的示例

我想要类似的东西，但在小提琴的左侧有多个“蓝色”分布。很可能分布下的区域是半透明和重叠的。

有什么策划的建议吗？它不需要情节。

谢谢。

您可以使用 fig.add_trace 添加任意数量的跟踪。遵循 plotly 中的相同示例：

import plotly.graph_objects as go

import pandas as pd

df = pd.read_csv("https://raw.githubusercontent.com/plotly/datasets/master/violin_data.csv")

fig = go.Figure()

fig.add_trace(go.Violin(x=df['day'][ df['smoker'] == 'Yes' ],
                        y=df['total_bill'][ df['smoker'] == 'Yes' ],
                        legendgroup='Yes', scalegroup='Yes', name='Yes',
                        side='negative',
                        line_color='blue')
             )
fig.add_trace(go.Violin(x=df['day'][ df['smoker'] == 'No' ],
                        y=df['total_bill'][ df['smoker'] == 'No' ],
                        legendgroup='No', scalegroup='No', name='No',
                        side='negative',
                        line_color='green')
             )
fig.add_trace(go.Violin(x=df['day'][ df['smoker'] == 'No' ],
                        y=df['total_bill'][ df['smoker'] == 'No' ],
                        legendgroup='No', scalegroup='No', name='No',
                        side='positive',
                        line_color='orange')
             )
fig.update_traces(meanline_visible=True)
fig.update_layout(violingap=0, violinmode='overlay')
fig.show()

将在左侧添加另一条轨迹：
