Shift the origin

Dear ROOTers

How can one shift the origin ((shift the 0 point on x axis))

i had several tries but always fail

i’m using the macro H_Burning.C to read two txt files properties.txt and masses.txt, into tree and then produce the graphs

masses.txt (13.8 KB)
properties.txt (15 KB)
H_Burning.C (1.73 KB)

htemp->GetXaxis()->SetLimits(0, 10);
htemp->GetYaxis()->SetLimits(0, 1);
