I already opened up an
issue on this, but I thought I'd ask here to see if anyone could help.
The problem with the ChartRangeFilter is that I can't change the date range by selecting and dragging the control. It just doesn't move at all. This is both in the Google playground, and in my code as well. This is a wonderful visualization for time series data, and it's a terrible shame that it doesn't work on the iPad. It works just fine on Safari 5.1.7 on Windows.
Any help that can be offered is appreciated.
