is an option for plot functions that specifies what legends to use.

Details

  • Typical settings for PlotLegends include:
  • Noneadd no legend
    Automaticuse automatic legending
    "Expressions"use formulas as legend labels
    {lbl1,lbl2,…}use lbli for the i^(th) input
    expruse expr as legend
    Placed[leg,pos]specify placement of legend
  • The following legend constructors can be used to form commonly occurring legends: SwatchLegend, LineLegend, PointLegend and BarLegend.
  • PlotLegendsPlaced[leg,pos] places the legend leg at the position specified by pos.
  • Possible forms for pos are:
  • Above,Below,Before,Afterpositions outside the bounding box for expr
    {h,v}horizontal h and vertical positions v
    {{ex,ey},{lx,ly}}scaled position {lx,ly} in the legend at scaled position {ex,ey} in expr
  • Possible horizontal positions include Before, Left, Center, Right and After.
  • Possible vertical positions include Below, Bottom, Center, Top and Above.
