The highcharts pie chart seems to require that the value of each slice is supplied as a percentage. I would like the tooltip rollover for each slice to show not simply its percentage of the pie but also the value represented. For example: the "John" slice of the sales pie should show that he made 50% of all sales and that meant he sold 44 cars out of 88 total.
In this example, I'd like to supply the y-value as 44, and to have highcharts convert this to a percentage by adding up the y-values of all other slices before drawing the pie.
Any way to do this?
