hello ROOT team
now I try to draw Xsection with expected limit like this http://inspirehep.net/record/901200/files/fig20.png
my data signals are
mass Xsection
500 .30430E-06
1000 .43762E-07
1500 .10090E-07
2000 .29253E-08
2500 .95735E-09
3000 .33629E-09
and backgrounds are .45655E-03
.24545E-02
assumed luminosity is 10 fb^-1
I studied some roostat examples but could not understand.
so if you know any solution or information, could you help me?
