ROOT

Dear Experts,

From py python-based applicaiton I’d like to redefine ROOT canvas type (Web/Root)

##  some python code 

some_root_object = ...

some_root_object.Draw()  ## here...

#

Is there a simple way to change the to/from Web-based/Rot based canvas type?
I see a way to change it via “$HOME/.rootrc” file , but it is noe very suitable for my purposes.
Are there alternative ways (except for “$HOME/.rootrc” file) ways to control the type of canvas,
e.g. environment variables or (better) explicit call for some ROOT functions?

Thank you very much in advance for the hints.

Thank you, Sergey @linev !
a tiny follow-up question:
can one choose i a similar way the browser type e.g. chrome vs firefox?
Thank you very much in advance!

Yes, firefox and chrome are reserved words.

ROOT.gROOT.SetWebDisplay("chrome");

But browser should be installed on the system and properly detected during ROOT compilation.

See TROOT::SetWebDisplay() docu
