Hello! I would like to remove the x-axis errors from a histogram. How can I do this?

Hi,

try
gStyle->SetErrorX(0.00001);

Thanks for the reply. I cannot see the difference. Since my plot contains multiple hists, does this command apply to all of them? For reference, a snippet of my code.

// Create canvas
TCanvas* c_nch = new TCanvas("c_nch", " ", 800, 600);
// Draw
c_nch->cd();
hist_nChPyZ0->Draw("PS");
hist_nChExLZ->Draw("same");
hist_nChExOZ->Draw("same");
hist_nChPy2W->Draw("same");
hist_nChExLW->Draw("same");
hist_nChExOW->Draw("same");
// Modify
gStyle->SetOptStat();
gStyle->SetErrorX(0.00001);

Is there a histogram-specific command that I could use before plotting itself?

Sorry, got it now. I added the c_nch->Modified(); command and it works :slight_smile:

Try moving the line with TStyle::SetErrorX() before the lines with TH1::Draw().
