The easy way is usually to combine the two DataTables together and use the view parameters of the charts to separate out the columns needed for each. If you are bound and determined to make your life difficult, you can instead set up the filters in a Dashboard for one chart, and create "statechange" event handlers for each of your controls that get the current state of each control and use those states to filter the data for the second chart. This is almost guaranteed to be more work than joining the two sets of data and using a single DataTable as the source for both charts (and the API even provides a method of joining two DataTables<https://developers.google.com/chart/interactive/docs/reference#google_visualization_data_join>that takes care of the hard part for you).
