TH2::Draw('col') circles instead of squares?

ROOT
1

Hi,

I have a TProfile2D histogram which I draw with the ‘colz’ option. I would like to have each of the bins drawn as circles rather than squares…

I suspect I need to draw square objects with circles cut out on top of my histogram? How would I do this in ROOT?
