Draw two H2D histograms on the same pad as TEXT but in different formats

ROOT

Hi,

I need to draw on the same pad some values in colours and also as TEXT with " 5.2f mrad" format and additionally indicate the element numbers with “2i” format. Here is an example code:

{
    TCanvas* c = new TCanvas("c", "c", 400, 400);
    TH2I* hi = new TH2I("hi", "hi", 2, 0, 2, 2, 0, 2);
    hi->SetBinContent(1, 1,  1);
    hi->SetBinContent(1, 2,  2);
    hi->SetBinContent(2, 1,  3);
    hi->SetBinContent(2, 2,  4);
    hi->SetStats(kFALSE);
    TH2F* hf = new TH2F("hf", "hf", 2, 0, 2, 2, 0, 2);
    hf->SetBinContent(1, 1,  4.5);
    hf->SetBinContent(1, 2,  0.5);
    hf->SetBinContent(2, 1, -3.5);
    hf->SetBinContent(2, 2, -4.5);
    hf->SetStats(kFALSE);
    TH2F* ht = (TH2F*)hf->Clone();

    gStyle->SetHistMinimumZero();
    gStyle->SetNumberContours(8);

    hf->SetMaximum( 4.);
    hf->SetMinimum(-4.);
    hf->Draw("COLZ2");

    gStyle->SetPaintTextFormat("2i");
    hi->SetBarOffset( 0.2);
    hi->SetMarkerSize(1.8);
    hi->Draw("TEXT SAME");

    gStyle->SetPaintTextFormat(" 5.2f mrad");
    ht->SetBarOffset(-0.2);
    ht->SetMarkerSize(1.8);
    ht->Draw("TEXT SAME");
}

Unfortunately, the “2i” format is overshadowed by " 5.2f mrad"…

How can it be avoided?

Thanks !

    TExec *ex1 = new TExec("ex1","gStyle->SetPaintTextFormat(\"2d\");");
    TExec *ex2 = new TExec("ex2","gStyle->SetPaintTextFormat(\" 5.2f mrad\");");

    gStyle->SetHistMinimumZero();
    gStyle->SetNumberContours(8);

    hf->SetMaximum( 4.);
    hf->SetMinimum(-4.);

    ex1->Draw();
    hi->SetBarOffset( 0.2);
    hi->SetMarkerSize(1.8);
    hi->Draw("TEXT SAME");

    ex2->Draw();
    ht->SetBarOffset(-0.2);
    ht->SetMarkerSize(1.8);
    ht->Draw("TEXT SAME");
}

Excellent!

Thank you very much, indeed!

At a second glance - not quite.

Works fine only with
TExec *ex1 = new TExec(“ex1”,“gStyle->SetPaintTextFormat(“3.0f”);”);

I’m using 6.08/06 on Fedora 24

Cheers

can you post the picture you get ?

The first one is 3.0f
The second is 2d

It seems the default format “g” works fine

    TExec *ex1 = new TExec("ex1","gStyle->SetPaintTextFormat(\"g\");");
    TExec *ex2 = new TExec("ex2","gStyle->SetPaintTextFormat(\" 5.2f mrad\");");

True!

Thanks a lot again!
