Hi,
Root allows you to simply change between a linear and a log scale for
the y-axis when you plot a histogram. However, I’m interested in using
a sqrt scale. (This has the advantage that the errors on all points will
have the same size.)
I looked around and found some mention about this in a fairly old post:
root.cern.ch/root/roottalk/roottalk00/0032.html
I looked at the TGaxis object and I guess one could use these axis objects
to piece together a sqrt scale that displays numbers of events such as
0, 1, 10, 100 etc. But then one has to manually create a histogram where
one has taken the sqrt of the data.
If someone has a simple way, or an example, that does this it would be
useful.
Thanks,
Anders
