Dear experts,
I am facing a very simple-looking but for yet unsolvable problem. I draw a histogram with set line style but no fill style and a limit y-range onto a canvas with logarithmic y-scale.
My problem is that bins whose content falls below the minimum of the y-axis is still displayed as a line that overlaps with the x-axis. This effect is highly undesirable since the actual x-axis and its ticks are not longer well visible.
I tried re-drawing the axis of the pad as well as re-drawing the histogram with the “axis” option – both without any visible impact.
Do you know of a way to circumvent this effect? Please find a piece of demonstrator code in pyROOT below.
hist = TH1F(“hist”, “hist”, 5, 0., 5.)
hist.SetBinContent(1, 0.)
hist.SetBinContent(2, 0.5)
hist.SetBinContent(3, 3.)
hist.SetBinContent(4, 6.)
hist.SetBinContent(5, 4.)hist.SetMaximum(10.)
hist.SetMinimum(0.1)hist.SetLineStyle(7)
hist.SetLineWidth(4)
hist.SetLineColor(kRed)
hist.SetFillStyle(0)c = TCanvas(“c”, “c”, 800, 600)
c.cd()
c.SetLogy()
hist.Draw(“HIST”)
Your help is very much appreciated!
Thanks allot in advance.
Best regards
Oliver
