Is there a way to manually set the tab-through order for data points in charts? The tab order works fine in column and bar charts, as it moves smoothly from one item to the next. But with line and pie charts (the only other two I've tried), it seems to jump randomly from one data point to the next as I try to tab through the chart. The ability to tab through the data points is pretty important for accessibility purposes, if someone is trying to view the tootips using only a keyboard.
