Dear all,
I've tried to create a 3d graph of my given data using the help from here - http://root.cern.ch/root/html/THistPainter.html#HP19
I''ll attach my macros to this letter, so you can try to examine it.
I have the two angles (let them be theta (0 - 90) and phi (0-360)) and elevation for each pair of angles.
My question is - why Bins with zero content have non-zero radius in spherical coordinates.
As you can see from my macros I fill only the half of the 180, so I want to see some kind of hedgehog, but in fact I receive the green semishpere which has non-zero radius.
And second question is why the shpere in fact looks like rugby ball in some projections, is there something I'm doing wrong?
Best regards, Dmitry.
