Is there a similar flag to "setCurrentDisplayedRangePreservedOnUpdate" on iOS version of charts?
I want to prevent line chart auto-scaling when new data is added.
And one more question. How to get visible points after zooming on line chart?
You should be able to set autoCalculateAxisRanges to NO on the iOS chart, which should give you the behaviour you need.
I'm not entirely sure what you mean by the second question - the points should be visible once the chart has rendered?
