Blob in final point of E4 draw option

Hi,

If I use the “E4” draw option, I always get a huge blob in the final (right-most) point of the plot, resulting probably from the smooth interpolation. Curiously, I don’t have a blob in the first point. For example:
{
TH1D * hist = new TH1D(“hist”, “”, 3, 0., 3.);
hist->SetBinContent(1, 4);
hist->SetBinContent(2, 3);
hist->SetBinContent(3, 4);
hist->SetBinError(1, .5);
hist->SetBinError(2, .5);
hist->SetBinError(3, .5);
hist->Draw(“E4”);
hist->SetFillColor(8);
hist->GetYaxis()->SetRangeUser(-2., 9);
}

Is there anything I can do about it? I work with root 5.26.00

use E3 as said here:
root.cern.ch/root/html/TGraphPainter.html#GP03

Well, ok, that’s without smoothed lines then, while I was looking for a way to get “E4” running. But fine anyway, now I know it’s a known problem :slight_smile:

Thanks!

Stefan
