I have data that is 10's of thousands of points per chart, so the named value pair form of the chart won't work. So I'd like to request a new feature. Where you let me use 1 or 2 indexes into the point data to define a series, but allow me to access all of the data from the tooltip. So for a line chart I would define the series by the array name, and 1 index and for a scatter chart I would define the series by the array name and 2 indices. But the this.point would refer to all the fields at that index. It seems that this would be logically equivalent to the name value pairs, except that the data expansion with all of the redundant strings wouldn't be there. It does represent some data expansion though so some hit for memory and performance would be there. But then the interactive options to the user would be far greater.

Provide a property for donut chart to show the aggregated total exactly at the center of donut
