I am having one scenario in that,I am having two tables like Doctors and OPL(Other Opinion Leader) OPL is nothing but they also doctors if some of doctors could not able to find the treatment then they will refer some other doctors for the patient,.That referred doctors known as OPL
My case will be,
There is one scatter chart in google map.If any body view the doctor on that particular geography,then it should show the OPL which he refered earlier.And Doctors bubble should be in one color and his OPL is another color.
For more clarity I have attached Doc with screen shot.Pls find the attachment.
