Description

As you can see the bar rod it has a pointer which is pointing towards the bar rod.

Let me explain. I am using the bar to showcase the marks of the student and i'd like to put the pointer beside the bar rod which will indicate the 'personal best score' of the student. The package uses the custom painter and paints the entire chart so i'm unable to add it. Can anyone help me with this?
