1D polar plots

Hi, I’m trying to draw 1d polar plots but ive read that root doesn’t support these plots, but that was 2005 when the latest message about this topic was sent. So my real question is has this issue been solved, and if so how can i call it up?

see class TGraphPolar and tutorial graphpolar.C
This class was introdued in 5.13.
An improved version is coming with the 5.14 release in December
