Highlighting of overlapping graph points

Question

I have a graph that shows multiple LineSeries, and is set to highlight the points on the graph as they are selected. However, occasionally points on the graph overlap (either within the same series, or different series with the same points), and in that case, the point is selected, but the highlight colour is not shown. Is there a way to get that to work?

Hi Michelle Barnett, 
 
We have analyzed your query and we would like to let you know that when we select any overlapping points in same series or different series, the last added data point only highlighted in overlapped position as per the below screenshot and it can be achieved by the HighlightOnSelection property of adornment. Please find the sample for your reference.

If the above solution does not meet your requirement, could you please share your exact requirement with more details for highlighting the selected point in line series, which will be helpful for us to provide a better solution at earliest.
