This is my first post and have to say I'm impressed by jChartFX. Awesome library!
I'm building a drill-down solution and need to get an ID for each bar the user clicks. I learnt how to get the index of the bar (evt.point), what is not of much use for me, unless I make a table (session, for instance) to relate the data array (that comes from a json string).
So, lets say that the json will return somethig like this (here, just one record):
{
store: "2114",
ID: "2",
Sales: 196.5,
Cost: 101.44,
Year: "2013"
},
The graph will show, say, X = store and Y = Sales.
The ID 2 represents all the record and when user clicks on that bar, I want to get the ID. As I said, I know how to the the index of the bar (and also the label, in this case, 2114).
The only thing I could thing of was to concatenate the store and ID fields wiht a known separator in order to get the ID. Something like store:"2114|2"
However this solution is far from being elegant, not to mention that the ID would appear in the graph.
Does anyone know a better way to handle it? The entire solution I'm buinding depends on this feature, as it will have multple levels fof drill-down.
