Swipe Gesture on Charts and minimum frame area


My user case is - Paginated scroll view controller having donut chart and bar chart in different pages. Size of the scroll view is not full screen. It is about 3/4th height of screen.

It is more like the functionality of stocks app.

Problems I am facing -

  1. Charts are not getting swipped in and out of scroll view if drag is over the chart area.

  2. It looks like donut chart and bar chart require some minimum rect to display it self. If scroll view frame (which is parent controller) is below a certain limit…both chart’s are getting cut off …instead of adjusting to new rect area provided to them for display.
