如何在 pandas DataFrame 中使用 MultiIndex 列 select 列（对于 ZD50F42A37901F21DE34BD 散点图）C？

Question

I have an aggregated DataFrame, with nested columns. How can I retrieve the aggregated columns, sum and count , as the x and y of a scatter plot?

I tried to use

sns.scatterplot(x="sum", y="count", data=xyz)

but it gave me keyError"sum" .

The only way it works is to retrieve sum and count as two lists, then scatterplot these two lists. But it takes a long time.

Is there any simple way to retrieve these two nested columns straight away?

Thank you.

From your picture it looks like you have a MultiIndex for the columns. If that's the case, you can access the columns by indexing with a tuple that specifies the values for each level:

sns.scatterplot(df[('Total', 'sum')], df[('Total', 'count')])
