Hi roottalk,
I'm seeing two odd behaviours, and I'm wondering whether I've misunderstood
something, or I've run into some bugs.
The first problem is that the value of gStyle->GetFrameLineWidth() affects whether the leftmost vertical line of a histogram is drawn, as demonstrated by the following macro (also attached):
void histdrawbug()
{
// Setting frame line width to 1 prevents the leftmost vertical line
// from being drawn over the ordinate
gStyle->SetFrameLineWidth(2);
TH1F* h=new TH1F("foo", "bar", 10,0,10);
h->SetLineColor(kRed); h->FillRandom("gaus", 1000); h->Draw();
The second issue is that the histogram drawing option "hist e ][" doesn't do what I expect it to, namely draw the histogram with errors and vertical lines between the bins, but with no vertical lines at the start and end. Instead I get no vertical lines at all.
Regards,
Philip
