Point-selection with crosshair tooltip Xamarin


#1

I am trying to add some functionality to my ShinobiCharts graph in the way that I would like a crosshair tooltip to appear above a point in the series when that point becomes selected. I have the functionality of selecting a point, and I have the crosshairs enabled.
I previously looked at this post: http://www.shinobicontrols.com/forum/shinobicontrols/2013/6/call-the-display-of-a-crosshair-without-touching-the-screen?p=0 however the solution to this problem is written in Objective-C and I am doing cross-platform development with Xamarin.
I did follow the instructions in the post on creating a datapoint, then setting the crosshair to that datapoint along with the custom label and the axis of my graph, however this didn’t work.

I am currently working on the iOS part of my application, so I am making use of a SChartDataSource. Does anyone else have any experience with this? Any help would be much appreciated.
