How to download a table of the data points in a chart?

We are build a dashboard in which we generated a series of charts.
As requested by the users, they need to have a table of the data points of each Chart. Currently, the users produced these tables manually.

Is there a way to download the data points of a Chart in a table? That is the "end" data points presented on a chart, not the data in "Click to expend group records".

Anyone's advice is appreciated.
