TH1::Draw Option "E"

[Erdrick]

When I draw a TH1 with error bars, there is a black dot at the center of each cross.
This is shown with the minimal example:

#include "TH1D.h"
#include "TCanvas.h"
#include "TLegend.h"

void temp() {

  auto hist = new TH1F("hist","",10,0,10);
  for (int i=1; i<=hist->GetNbinsX(); i++) {
    hist->SetBinContent(i, 2*i);
  }
  hist->SetLineWidth(3);
  hist->SetLineColor(2);

  auto canvas = new TCanvas("c1","");
  hist->Draw("e");

  canvas->SaveAs("canvas.pdf");

}

Which produces canvas.pdf:

I was not expecting a black dot to appear at the center of each cross, especially since I have set the line color to red. How do I prevent this? I could not find any information at https://root.cern.ch/doc/master/classTHistPainter.html. Sorry if this question has a trivial answer.

@Erdrick

hist->SetLineColor(2);

Try also change marker color to red:

hist->SetMarkerColor(2);
