Hi Andy and ROOTers,
let me add a few words here. Since a few years I do data analysis with
ROOT, so using trees, histogramming, statistics etc.
1)
My experience with feed back is very positive - at least concerning
bug fixes in TH-statistics.
2)
But the inheritance tree of the histograms is really annoying. Many times
I have to check the input of a routine:
void MyMethod(TH1 *hist)
{
if(!hist || hist->GetDimension() > 1) {
this->Error("MyMethod", "not implemented for %d-D hist",
(hist ? hist->GetDimension() : 0));return;
3)
I also stumble regularly over the fact that some graphics attributes are
stored together with the histogram, some are directly used from gStyle
(e.g. gStyle->SetErrorX(0.))
Cheers
Gero
