Marking selected points in a Graph

Is it possible to mark selected points in a XY graph ?

 

Lets say i have a XY graph which is made from an array. Now I want to hightlight a point with a ring or square point at specified index, say index  4 ; from the example below i want to hightlight the data points 12 & 54 See attachment.

 

I tried to use MAP to XY Coordinates Invoke but couldnt go further. Is there any idea to do it?

 

Thanks

Hi Christoph

 

Thanks for your help. I was already trying to use the Annotation property and ws succesfull in implementing it but only problem is that only the last value is being shown in the graph. See attachment.

I will try your VI now.

I would just use a second plot with large points.
