Having this issue also.

I have a handful of PlotModels in a Grid, which is contained within a scrollview. On Android, this works perfectly well, as said by naveeng2228. But on iOS, Scrolling can only be achieved by interacting with non-oxyplot elements of the UI, such as boxviews, blank spaces, etc.

However, I can interact with PlotModels using TouchStarted, TouchDelta, TouchCompleted..

Does anyone has resolution for this problem?

Still there is no resolution from OxyPlot Team. But I have temporally solved this issue by overlapping OxyPlotView with a transparent AbsoluteView. I am expect a solution from the OxyPlot Team.

@nvngogineni can you show a detailed example of your fix, please?

The bug still exists. What I did is I overlapped the graph view with a transparent UIView with same width and height to enable scrolling. But I think user interaction with the graph is not possible anymore (like scrolling or selecting graph points) but I do not need this.
