Hi, I am trying to overlay a bunch of graphs, so I make a dumb one to start with y-axis range from 0.75 to 1.1 const Int_t m=2; Float_t x1[m],z[m]; x[0]=0.0; x[1]=20.0; y[0]=0.75; y[1]=1.1; TGraph *g = new TGraph(m,x,y); g->SetTitle("Efficiency vs.Threshold for CEM(1,x) CJT(2,7 or 10)"); Then I create a bunch of other graphs with stuff in them TGraph *gr1 = new TGraph(n,x,y1); TGraph *gr2 = new TGraph(n,x,y2); etc. Then I draw my dumb graphs and create a legend g->Draw("AP"); gr1->Draw("P"); etc. leg = new TLegend(0.6,0.6,0.9,0.9); leg->AddEntry(g,"CJT(2,7)","l"); leg->AddEntry(gr1,"CJT(2,7)","l"); leg->SetHeader("Thresholds"); Then draw it. leg->Draw(); The problem is that the font in the legend comes out really small. It seems intimately connected to the y-range of the axis. If I make the range 0-1 it works great. The problem seems to occur when I make the lower bound non-zero....I get linear shrinkage as I approach the upper bound. Any ideas? It is as if it is not using NDC anymore.... I am using ROOT v3.01/06.
