Is this a recommended approach? The charts are amazing and I'd love to just wire up both a grid and chart to one store and have them interact w/ each other.
One issue I've found is that when a grid column header is sorted, the pie chart will redraw itself. This isn't exactly ideal since slice colors and order changes. So it's a bit misleading since a user may think the data has changed when it has only been sorted.
Can this behavior be disabled or worked-around?
Check here for an example: http://ajpfister.com/sandbox/ext4tests/grid_chart.html. Just sort some columns and notice the pie chart changing every time.
