I am using HighCharts currently with ExtJs 3.x and have started writing new code with ExtJs 4.x and the built in Charting functionality.

One thing I use a lot from HighCharts is the combination series where Pie chart is used as a summary tool for the larger chart (example: http://www.highcharts.com/demo/combo)

Is it possible to do something similar with ExtJs 4 charts?? I dont see a config option for specifying the size/position/center of the Pie series and hence I am not sure if this can be done with ExtJs 4...
