You will have to use a DataView to merge those two columns into one:
var view = new google.visualization.DataView(data);
view.setColumns([{
type: 'string',
label: 'Name',
calc: function (dt, row) {
return dt.getValue(row, 0) + ' ' + dt.getValue(row, 1);
}
}, 2, 3]);
Use the DataView to draw the chart instead of the DataTable.
