Well, I've tried both: viewing it from different angles and myhist.Smooth(), as in Rene's advice.
Changing the angles doesn't work, the surface just remains difficult to interpret
And myHist.Smooth works perferctly well for xyz coordinates, but smth's still wrong with smoothing in spherical coordinates. Or, probably, it just the way it goes normally..

Just in case, here's my macros. You can run and change angles at your own if you want.
Maybe we'll figure out what's wrong together))
