    Default [2.1.0-RC1] Charts - BarChart scroll performance

    [2.1.0-RC1] Charts - BarChart scroll performance


    Hi,
    I am getting some feedback on the Chart application I have created.
    There main concern are the scroll performance on the BarChart/ColumnChart (On all devices iPhone/Android)

    I think the problem is that its not very smooth and that its not momentum scroll os the rest of the application. That behaviour is strange/confusing for the end user because the scroll acts different on the charts.

    I have two questions:
    1. Will the scroll ever be as "smooth" as the normal scroller? (I know its Canvas and the behaviour is different because the X line is always visible etc.)
    2. Is it posible to use the normal scroller? I know the price would be having the x line visible and more. But just having the chart in a panel that scrolls. If, how is this possible?

    Sure, but I would also like to know the answer to the two questions?

    There is nothing special about the Chart, its just like the KitchenSink only difference is:
    Code:
    visibleRange: [0,0.2]
    That will make it scrollable.


    I can create a test project if you want? But its just like the KitchenSink...

    Do you need me to create a test case or is it good enough?
