Since you already have the data it would make most sense to create the charts in your "click" handler.
Check the "Binding to local data" examples for a syntax reference.
If you don't want to load all the data in advance then use a data source on each chart, as in the "Binding to remote data" demos.
This will save you the trouble of sifting through the initial data, but will require dedicated service for each chart.
I hope this helps.
