Is it possible to mark each bubble with a number or letter 1,2,3,4,5 etc. or A,B,C,D, etc

In a way - you could use the ondraw RGraph event to have a function run whenever the chart is drawn. This function could then use the coords array to position some text "over the top" of the bubbles.

Have you an example of the ondraw RGraph event with the coords array?

Thank you
