Multipad graphics

Dear all,

I write to ask suggestions concerning the graphics of a multipad. Basically, what I would like to have is two vertical pads, attached to each other. This is what I get, but as you can see from the attached figure, there are some issues concerning the axis labels. For instance, I would like to have the X label only on the lower plot, while there is some overlap between the labels on the Y axis.

Could you give some suggestions?

Thank you!

Best regards

Yes I can :slight_smile:
But the best is to send me the small macro you made to produce this plot and I’ll modify it for you.

Thanks for the macro you sent me. As far as I see the only remaining issue is the overlapping labels on the Y axis.
It seems you manage to have the X axis labels only on the lower axis.
Right ?

void MultipadTest( ) { 


  double DOSE[8] = {0., 1., 5., 10., 25., 50., 100., 140.};
  double DOM[8] = {0., 80., 338., 675., 1308., 1941., 2502., 2660.};
  TCanvas *c1 = new TCanvas("c1","multipads", 800, 700);

  TPad *p1 = new TPad("p1", "p1", 0.2, 0.1, 0.8, 0.5, 0, 0, 0);
  TPad *p2 = new TPad("p2", "p2", 0.2, 0.5, 0.8, 0.9, 0, 0, 0);

  TGraph *gr = new TGraph(8, DOSE, DOM);
  gr -> SetMarkerStyle(20);
  gr -> SetMarkerSize(1.5);
  gr -> GetXaxis()->SetTitle("");   
  gr -> GetYaxis()->SetTitle("");   
  gr->SetMinimum(-100.); // Allow to make the 0 on Y axis higher
  p1->cd(); gr -> Draw("AP");
  p2->cd(); gr -> Draw("AP");

Thank you, now it looks already much better. However, I still have one problem. I still get the label on the X axis of the upper plot. I would like to skip it, since it is identical to the lower one. How can I do this?

Thanks again!

You should set the label size to 0 for the upper plot:
