Changing width of marker (P) or line(L) in TLegend

Does anyone know how to change the width (shrink it) the part of the TLegend where the marker § or line (L) is displayed? I would like to show shorter lines and have less white space around my markers.
Thanks in advance,
PS I’m using most recent version of root.

do something like:

// draw the legend TLegend *legend=new TLegend(0.6,0.65,0.88,0.85); legend->SetMargin(0.15); //default is 0.25 TLegendEntry *le1 = legend->AddEntry(histo,"Data","lp"); le1->SetLineWidth(1);
