Hi rooters,

Here’s a simple question but I can’t get it to work. How do I delete a tgraph in root? What I read in root user guide is something like:

f1->Delete("graph_a1_b2;1");

assuming f1 is my current directory/rootfile. However I used the command and .ls again the object is still in the root file. I suspect the problem is that the object’s name has underscore in it but I could be wrong.

Thanks!

Make sure you have write permission to the root file, and open it with the “UPDATE” option.

Thanks! Wow, indeed I forgot to open it in “UPDATE” mode. A newbie mistake

The command-line tool rootrm can also be used.
