RE: set a line in a TH2 ("POL") plot

Hello,

1- Right now there is no axis on polar 2d coordinates plots. 2- You can use TPolyLine3D but you will have to draw it in the normalized space used to draw the 3d polar plot.

Cheers, O.Couet

Subject: [ROOT] set a line in a TH2 ("POL") plot

Hello,

(2) related questions;

I have a TH2 Polar plot, How do i make an angular axis pop up?

i would like to segment it into slices in the angular coordinate. Do you know how i can draw a line at theta=0,x,y,z etc..? ..so that when i

spin the graphics box, the lines still move with the axis.

*snippet of plotting code below*

cheers,

Dan.

TH2F *CSCTF_etaPhiPlot = f.Get("SPTrack Eta-phi"); TCanvas * CSCTF_etaPhi_PlotCanv = new TCanvas("eta-phi","eta-phi",1); CSCTF_etaPhiPlot->Draw("POL,LEGO1");

..looks pretty but has no axis...
