Glass-like bubbles in BubbleChart

Hi,

I would like to know how to make a BubbleChart look like in the gallery:

Is there a "ready-to-use" way to do it, or is this a combination of different gradients, overrided or custom paint operations, or anything else?

With TBubbleSeries I have transparency and different gradients (gdRadial is the best one), but nothing like this. Unfortunately, clipping at the edge of the chart area does not work if I use transparency or Gradient.Direction=gdRadial: The bubbles overlap the axes.

(Delphi VCL TeeChart Pro, TChart component with TBubbleSeries)

Thanks in advance
