One more question, is it possible to switch from multi series chart like stackedBar, stackedColumn graph to pie graph or doughnut graph?
Pie/Doughnut charts doesn’t support multi-series as of now. However switching between stackedBar/stackedColumn to pie/doughnut works fine where chart accepts and renders only first dataSeries.
The data of this graph comes from a json and I dont want to have a duplicate in the year. Can you please tell me whats going on? Thank you. This is my json
Can you kindly create jsfiddle with sample data, so that we can understand it better and help you out?
