Hello all,

does someone know how to draw a TPave without a shadow?

Thanks a lot

One possible way:

TPaveText *pt = new TPaveText(0.01,0.9,0.4,0.9,“blNDC”);
pt->SetBorderSize(1);

I tried this, but doesn’t seem to work. I still get a shadow in the box.

I get no shadow with this:

{
//=========Macro generated from canvas: c1/c1
//=========  (Fri Mar 17 15:21:20 2006) by ROOT version5.11/01
   TCanvas *c1 = new TCanvas("c1", "c1",15,47,700,500);
   c1->Range(0,0,1,1);
   c1->SetFillColor(0);
   c1->SetBorderSize(2);
   c1->SetFrameBorderMode(0);
                                                                                
   TPaveText *pt = new TPaveText(0.274425,0.351695,0.768678,0.709746,"blNDC");
   pt->SetBorderSize(1);
   pt->SetFillColor(19);
   pt->Draw();
   c1->Modified();
   c1->cd();
   c1->SetSelected(c1);
}

hi olivier,

I am using commands in my rootlogon.C so that my canvas conforms to my experiment’s standard, so I am not sure if I want to make the changes you suggest to the canvas.

However, I tried pt->SetFillColor(19), but it doesn’t work. The box still has a shadow.

I do the following in my macro,

TCanvas c1;
c1.Divide(2,2);
gStyle->SetOptStat(0);

histA->Draw(“e”);
TPaveStats *pt=new TPaveStats(0.7,0.75,0.8,0.85,“blNDC”);
pt->AddText("(a)");
pt->SetBorderSize(1);
pt->SetFillColor(19);
pt->Draw();

c1_2.cd();
…

Also, the text (a) comes out boldfaced. How do I make it regular font?

The following macro gives me the attached plot which, seems to me, is what you are requesting.

{ TCanvas c1; c1.Divide(2,2); gStyle->SetOptStat(0); hpx->Draw("e"); TPaveStats *pt=new TPaveStats(0.7,0.75,0.8,0.85,"blNDC"); pt->SetTextFont(40); pt->AddText("(a)"); pt->SetBorderSize(1); pt->Draw(); }

ah, sorry, I used wrong terminology.

I want to get rid of the gray background in the box.

also, I want to make the (a) not boldface.

8

lastly, can I get rid of the boundary around (a).

So, basically, I just want (a) sitting in one corner of the plot.

pt->SetFillStyle(0);

the font is choosen thanks to:

pt->SetTextFont(40);

it is not bold. It is helvetica. Helvetica bold is 60

// 10 : times-medium-i-normal timesi.ttf
// 20 : times-bold-r-normal timesbd.ttf
// 30 : times-bold-i-normal timesi.ttf
// 40 : helvetica-medium-r-normal arial.ttf
// 50 : helvetica-medium-o-normal ariali.ttf
// 60 : helvetica-bold-r-normal arialbd.ttf
// 70 : helvetica-bold-o-normal arialbi.ttf

thanks.

Is it possible to remove the boundary around (a)? I looked at functions like SetLineWidth(0), but they don’t seem to do anything.

pt->SetLineColor(0)

thanks for your help. it works now.

Note that with all these settings you end up drawing a simple text … May be it would be more logical and efficient to simply draw a TText or a TLatex. But you surely have very good reasons to proceed so.

duh! of course, you are right :wink:

I started with TPave because I took it from another macro I have, and never thought of doing a simple TText or TLatex…
