Examples

Basic Examples  (1)

Wolfram Language code: Needs["PlotLegends`"]

Density plot with a legend:

Wolfram Language code: ShowLegend[DensityPlot[Sin[x y], {x, 0, π}, {y, 0, π}, Mesh -> False, PlotPoints -> 30], {ColorData["LakeColors"][1 - #1]&, 10, " 1", "-1", LegendPosition -> {1.1, -.4}}]

Surface plot with a legend:

Wolfram Language code: ShowLegend[Plot3D[Sin[x y], {x, 0, π}, {y, 0, π}, ColorFunction -> "Rainbow"], {ColorData["Rainbow"][1 - #1]&, 10, " 1", "-1", LegendPosition -> {1.1, -.4}}]

Plot with a legend for the filling styles:

Wolfram Language code: ShowLegend[Plot[Sin[x], {x, 0, 10}, Filling -> Axis, FillingStyle -> {Red, Blue}], {{{Graphics[{Blue, Disk[{0, 0}, 1]}], Sin[x] > 0}, {Graphics[{Red, Disk[{0, 0}, 1]}], Sin[x] < 0}}}]
