Gordon,
We didn’t support this for now. If you understand the logic how to get the hot spot based on the density of points, you can easily accomplish it yourself by creating your own pointStyle and overwriting the DrawCore method. We don’t have an integrated one now, if you can provide us the logic, we can create that style for you.
We have a built-in DotDensityStyle which is to render points on an area based on a value from the feature data. That’s not exactly what you want but it might give you some insights. Please have a look at the sample ( Styles->DotDensityDrawingUsingNumericalData) if you are interested.
Let us know if you have any issues.
Thanks,
Ben
