Is It similar?

But i want to get every point not only the points in dataset. Can i get that information??? Thank you very mu...

I am also implementing this function too.
Can you share a short example!

Thank very much!

It seems that i can not use FastScratterPlot because i need the value in x-axis and y-axis are double not float:(!

Other way, is there any example of FastScatterPlot??

Any one could give me some suggestions !
