Dear Basit,
your batch is absolutelyu correct.
It will work.
The process
pp → t¯tb+X
etc should be implemented in exct analigy.
Best regards,
Alexander

But ,Sir I am facing a problem . It shows distributions along yaxis are empty.
How to set distributions along yaxis? otherwise graph goes parallel to xaxis.

It gives you what you are asking.
You have asked to plot M(H) which is a fixed number,
say 100,
and you want to put this number into histogram with the range
2001000
so you have will have an empty histogram.
I.e. you have got what you have asked

Sir,
It shows empty yrange . adjusting to {1:1}
I want to fix this problem .so that i will able to get proper plot

Warning: empty y range [0:0], adjusting to [1:1]
is a WARNING.
This is not and ERROR.
For 2D or higher dim scans it does not plot cross sections
at
../calchep/
and this si reflection of this
It does make a plot (distributions) for individual points of the scan
as soon as they defined correctly (which was your problem).
For example if you would define
Dist parameter: M(H)
Dist min: 0
Dist max: 1000
Dist n bins: 100
Dist title: p,p>t,H,j
Dist xtitle: M(H)(GeV)
i.e.
Dist min: 200 > Dist min: 0
then you would get non empty distribution
in
.../calchep/
etc for example
as I have explained you in my previous message
Is this clear now?
