Attaching circles to a bar plot

ROOT Version: 6.14
Platform: MacOS


I am trying to add half circles to a bar plot, with width of each bar of a bar plot being different (something like the attached hand drawn figure). Is it possible to do in Root?

I searched for examples, but I did not find any. May be I am using wrong keywords. So I will appreciate any help pointing me to an example.

Thanks for your time,

Thanks for your example. It clearly shows what you are looking for. We do not have such plot as a predefined option in ROOT. You will need to make a macro to draw the circular part of your plot. I guess the basic primitive(s) to be used to draw these circles will be TArc or TCrown.
