Very nice job! I have added a couple of comments.

Could you also have a look at this code:

QualityControl/Modules/ITS/src/ITSFeeTask.cxx

Lines 483 to 502 in 9c9a6c5

	mLaneStatusSummaryGlobalCanvas->cd();
	mLaneStatusSummaryGlobalCanvas->Clear();
	TLine* mLaneStatusSummaryLine = new TLine(0, 0.1, 4, 0.1);
	mLaneStatusSummaryLine->SetLineStyle(9);
	mLaneStatusSummaryLine->SetLineColor(kRed);
	mLaneStatusSummaryLine->SetBit(TObject::kCanDelete);
	TLatex* mLaneStatusSummaryInfo = new TLatex(0.1, 0.11, Form("#bf{%s}", "Threshold value"));
	mLaneStatusSummaryInfo->SetTextSize(0.05);
	mLaneStatusSummaryInfo->SetTextFont(43);
	mLaneStatusSummaryInfo->SetTextColor(kRed);
	mLaneStatusSummaryInfo->SetBit(TObject::kCanDelete);
	TH1F* mLaneStatusCanvasMember = (TH1F*)mLaneStatusSummaryGlobal->Clone("mLaneStatusCanvasMember");
	mLaneStatusCanvasMember->SetBit(TObject::kCanDelete);
	mLaneStatusCanvasMember->Draw("histo");
	mLaneStatusSummaryLine->Draw("same");
	mLaneStatusSummaryInfo->Draw("same");

Here we create and draw a TCanvas with Line and Tlatex to make plot more clear (I will send you example of figure to the mattermost)

Thank you for the changes. I have only couple of minor comments

@iravasen the PR is fine from my side. Do you have any comments?
