Change marker size of the TLegendEntry returned by AddEntry

[Karl007]

Hi, I have a small problem, which is, when I add an entry to a legend using:

  TLegendEntry* l2 = leg->AddEntry(h1, "particle1", "fp");
  l2->SetMarkerColor(2);
  l2->SetMarkerSize(1);
  //l1->SetTextSize(350);
  l2->SetMarkerStyle(8);

The entry will be shown but it will inherit the markers style from h1 instead of showing the style I need using the above methods.

Instead of “l2->Set...”, use “h1->Set...”.

Hi @Wile_E_Coyote ,

Thanks for your answer. If I change l2 to h1 indeed legend marker will change, however, h1 markers will change too.

What I want (if possible) is to change only the legend marker.

Then don’t add the histogram as entry. You can create a TMarker of the type you want and then add this marker as entry in the TLegend.

TMarker *m = new TMarker(.1,.1,21);
TLegend *leg = new TLegend(0.1,0.7,0.48,0.9);
leg->AddEntry(m,"test","p");

Hi @dastudillo,

Nice. This worked fine:

TMarker *m = new TMarker(.1,.1,21);
TLegend *leg = new TLegend(0.1,0.7,0.48,0.9);

m->SetMarkerColor(2);

leg->AddEntry(m,"test","p");
