Nancy had asked for a sample on TreeChart . Here is a quick component I built for
Nancy . Ofcourse you can customise colours .. Sorrry I think my colour combinations are bad
You can download the source here
1> Tree chart takes Hierarchical data as input .
2> Every node should have Name(Level as used in example[ It gets displayed in the chart] ) and value ( per in the example [ its the percentage]) and color ( the color of the area)
3> labelName should be mapped to Name and perName should be mapped to value
Look at the sample named testChart from the downloaded source .
Thank You Nancy for bringing up a good requirement :)
