You are also facing the new issue that you need to get your own mapsApiKey in order to use the geocoding service. That might explain some of your other issues as well.

The problem with the invalid column index appears to originate in angular2-google-chart.directive.ts, in the drawGraph method. The caller of getValue in this line in the 'select' listener looks suspicious:

selectedRowValues.push(wrapper.getDataTable().getValue(selectedItem.row, selectedItem.column));

The selectedItem.column is null. This looks like a bug since it is not always true (for all chart types) that the selected item has a row and a column.

I would suspect that the getSelection problem also probably stems from the same issue.
