Draw a Diamond.

A diamond is defined by:

Its central left coordinates x1,y1
Its top central coordinates x2,y2

A diamond has line attributes (see TAttLine) and fill area attributes (see TAttFill).

Like for the class TPaveText, a TDiamond may have one or more line(s) of text inside.

 
TCanvas *diamond(){
   TCanvas *c = new TCanvas("c");
   TDiamond *d = new TDiamond(.05,.1,.95,.8);
 
   d->AddText("A TDiamond can contain any text.");
 
   d->Draw();
   return c;
}
