Thanks you Haritha.
Two more questions,
1. Is it Possible to show the Y Axis on the center with the labels as shown in my attachment? Instead of on the left side. I mean I need the Y axis line with labels on the center where you are showing a vertical line(0,0).
2. Is it possible to zoom this bubbles ?
3. Is it possible to show some information on click of each bubble specific to that point?
Thanks
