March – plotting in Mathematica

Here's a plot for Mathematica that you can use as a template to plot ListLinePlot and Plot in the same figure. Font sizes are increased to be well visible in a research article.

xmax = 150;
ymax = 0.025;
Show[
 
 ListLinePlot[{Table[{t, 
     PDF[GammaDistribution[3.715287738432738`, 16.575007504627795`]][
      t]}, {t, 0, xmax, xmax/10}],
   Table[{t, 
     PDF[GammaDistribution[6.502676225156808`, 8.60919186301341`]][
      t]}, {t, 0, xmax, xmax/10}], 
   Table[{t, 
     PDF[GammaDistribution[3.3444580518527207`, 16.73897127052263`]][
      t]}, {t, 0, xmax, xmax/10}]}, 
  PlotRange -> {{0, xmax}, {0, ymax}},
  PlotLabel -> PDF,
  AxesLabel -> {Style["SIR", 16, Bold], Style["", 16, Bold]}, 
  PlotLegends -> Placed[{"Sim 1", "Sim 2", "Sim 3"}, Right], 
  PlotMarkers -> {Automatic, 10}, BaseStyle -> {FontSize -> 15}],
 Plot[
  {
   PDF[GammaDistribution[3.715287738432738`, 16.575007504627795`]][
    t],
   PDF[GammaDistribution[6.502676225156808`, 8.60919186301341`]][t],
   PDF[GammaDistribution[3.3444580518527207`, 16.73897127052263`]][t]
   }, {t, 0.01, xmax}, PlotStyle -> Thick, 
  PlotLegends -> 
   Placed[{"\[CapitalGamma](3.7, 16.6)", "\[CapitalGamma](6.5, 8.6)", 
     "\[CapitalGamma](3.3, 16.7)"}, Right]]
 ]

Output:
