[2.1.0-RC1] Charts - BarChart scroll performance
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:
- 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.)
- 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?
