Removing vertical lines from PDF plot

Dear experts,

I wish to plot a PDF, representing the total background expectations,without the vertical lines at the left and right most part of the plot. Basically I would like to use “][” draw option seen here: I tried to implement this via DrawOption("]["), but then the entire line isn’t drawn. The command I am using is:


Is this supported? I am using ROOT 5.34/14


I am not sure if plotOn support this option … have you tried to plot it with the regular TH1::Draw() ?
