描述
When creating a scatter_matrix using plotly express:
import plotly.express as px
df = px.data.iris()
fig = px.scatter_matrix(df,
dimensions=df.columns[0:4],
color=df.columns[4])
fig.update_layout(
autosize=False,
width=1200,
height=1200,
)
fig.show()
then highlighting a subset of the data using the lasso or rectangular selection tool also highlights the corresponding points in the other graphs.
However, when marking points in two plots I would often prefer that not the union of those are highlighted but the intersection. In the example image below this would mean that only a few red and green points are still visible/highlighted, but no blue points.

This is the feature I would like to have: A way to control whether the union or the intersection of all selections are highlighted.

调研方向
首先跟踪 lasso 和矩形选择如何在 plotly.js 的 scatter_matrix 示例中传播。定义并实现一种选择并集或交集行为的方式,然后验证多个图中的选择是否准确高亮所请求的组合集合。
