Have you had a look at this sample?
Basically you need to have a a puntal data source with some attribute data. The value for the heat layer needs to be in the range [0...1]. You can achieve that by
  • passing a scale factor (HeatValueScale), or
  • a delegate function (HeatValueComputer).
You can assign a color blend to render the heat map (HeatColorBlend).

You can define a OpacityMin and OpacityMax value for the heat layer dots.

You can assign a base layer that is rendered right before the heat layer.

What else do you want to know?
