Hello Rooters,
Is gStyle -> SetHistLineWidth() supposed to change a histogram line
width in the Postscript output? The following macro reads histograms
from the hsimple.root file and the Postscript output is the same whether
I use gStyle -> SetHistLineWidth(1) or gStyle -> SetHistLineWidth(10).
I have been using root 2.23/12 under SunOS5.7.
Thank you and best regards,
Michal Lijowski
