There is no built-in mechanism to support this, but there are a couple different ways you could implement it using HTML checkboxes.
I would probably recommend that you use a DataView with the setColumns() method to set the columns based on the checkboxes that have been selected. This assumes you first request all the data for all the currencies, each one in its own column, and put that in a DataTable, and then generate the DataView from that. See https://developers.google.com/chart/interactive/docs/reference?hl=fr-LU#DataView_setColumns You could instead make repeated requests to your server with a different query that you determine from the checkboxes. This would take more time to generate each display, but you would avoid sending all the data for all the currencies, which could slow down the initial request for data if there is a lot of data.
