ChartTouchDelegate never called

[almaskz]

Hello guys,

Great job with the lib. I cannot find where you call handleTouchEvents(_ touches: Set, event: UIEvent!) ChartTouchDelegate delegate methods in CombinedChartView or anywhere else in the project, hence it never gets called.

Check ChartsDemo please or search through the code and add some breakpoints so you will know.

Basically, it's in pan gesture handlers and tap gesture handlers in BarLineChartViewBase for example.
