Hi,
if you save as "myCanvas.C" you can run root
and type
.x myCanvas.C
and you ll get the canvas drawn again.
This is useful if you changed attributes of
elements in the canvas interactivly (like
text sizes, colors etc.) to make it look
nice for a presentation say.
You may also edit myCanvas.C to beatify
things further. Also a good way to learn
how to write root macros.
if you save as "myCanvas.root" you all get
a root file.
again run root and do:
TFile f("myCanvas.root");
f.ls();
myCanvas->Draw(); // if canvas name was "myCanvas"
Cheers
Otto
