Hi,
I have a top N style bar chart with 2 series, inputs and ouputs. X axis is company names, and y axis is an aggregate of the amount. This is much like the documentation at http://docs.telerik.com/devtools/wpf/controls/radchart/features/grouping/and-aggregation and the second last picture where you show the sum of all apples and bananas per year and region. For 2008 I have inputs, and for 2009 I have outputs, for regions I have companies and for quantity I have amount. I have the correct data displayed, but I want to sort the data so that, in your example, the region with the highest 2008 figure comes first, so Europe(331) is on the top, then North America (322), then Asia (316). In other words the sorting is defined by one of the series. How can I do that?
Thanks
