How to get all the Marker points in line graph with multiple lines.

I am implementing line chart with Multiple(Two) lines (Sales of current month and previous month on the day basis).
On graph click we can pop up a view (BalloonMarker) which shows Graph Point.
But there is a limitation. It shows only one line point.
Is there way we can get points for both lines? And display round circles on selected points on both lines?
I also need to customize BalloonMarker view.

I have attached current and expected layout image:
