It looks like the SURF1 option with the SPH option has some problems in
that case.
Use GLSURF1 instead of SURF1 it looks much better.
We are putting more effort on the GL display right now. For both 3D plots like yours but also for 2D.

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))

Have you tried to rotate it to understand it better ? maybe that's just a matter of viewing angles ....

ok, thanks.
but still i don't understand why surf1 plot looks like a mess (while i
thought it should look just like lego2 but smoothed).
Cheers,

A lego is a lego .. it cannot be "smoothed" as you request. A smoothed representation will be a surface. And SURF1 corresponds to the "smoothed version of the lego2 option".

i've already tried all types of SURF but it didn't help much Here's the example of SURF1, which is also difficult to interpret.
I just want to see my LEGO2 plot as it is on the right panel of my PNG
but with the smooth net.
Maybe there is another way instead of using these drawing options?

Use SURF1 instead of SURF2.

Dear all,
I've made a draft of 3D spherical plot, you can see it in attachment. It is plotted both with SURF2 (on the left panel) and LEGO2 (on the right panel) options.
Is it possible to make smooth LEGO2 plot, I mean with smooth contours
instead of these square bins. Because SURF2 visualization is difficult
to interpret.
Maybe some special drawing option?
With best regards,
Kotov Dmitry
