Draw sector as TH2F in polar coordinates

ROOT
1

Hi everyone!

I want to draw a sector as 2d histogram.
The problem is. I didn’t figured out how to set bin regions in polar coordinates.

I want it to be with:
phi_start = -15 deg
phi_end = +15 deg
r_min = a cm
r_max = b cm

Is it possible to easily make a fancy plot as attached?

thanks and cheers!

Hi,
try to have a look to THistPainter 2D option, I think that the option polar is what you need. Instead of x you have the angle and instead of y you have the radius.

Cheers,
