Big thanks! After fiddling around and getting familiar with the code I was able to adjust your solution to my issue and it works great, just needs some fine-tuning.
Now I only have 2 questions and hope you could help me out with it based on your solution in the other thread. Question 1 (High priority): At this moment all the data gets recalculated to compare it against each other from the get go. Is there a way that, when I set the initState to just one value (in my case Column A) that it just shows the original data without calculating and as soon as someone adds at least one Column from the Category Filter, the data will be calculated so that they can be compared relative to each other. => Follow up: Is there a way to not show Column A in the Category Filter, since I always want it visible as default data. Question 2 (Low priority): Is it possible that Column A (by default always visible) is an AreaChart and the other Colums (B, C, D, E etc...) when selected will be a LineChart? Would be great if you could help me out with this and to keep it simple lets use http://jsfiddle.net/asgallant/EVQP2/ as basis and then I will be able to adapt the solution to my chart. Thanks a bunch!
