Chris, You can either insert your additional columns in every row of the array of arrays that you give to arrayToDataTable() or you can add columns to an existing data table using addColumn() or addColumns(). See https://developers.google.com/chart/interactive/docs/reference#DataTable_addColumn
If you want to provide custom tooltip content, rather than just getting the default tooltip, see https://developers.google.com/chart/interactive/docs/customizing_tooltip_content#custom_content But you actually said "change the tool tip to a bar graph", which suggests you want to see a bar graph in the tooltip. That is possible too, but quite a bit trickier.
