ComplexRegionPlot

ComplexRegionPlot[pred, {z, zmin, zmax}] makes a plot showing the region in the complex plane for which pred is True.

ComplexRegionPlot[{pred1, pred2, ...}, {z, zmin, zmax}] plots regions given by multiple predicates.

Examples

Plot a region in the complex plane:

ComplexRegionPlot[Abs[z] < 1, {z, -2 - 2 I, 2 + 2 I}]

Plot multiple regions:

ComplexRegionPlot[{Re[z] > 0, Im[z] > 0}, {z, -2 - 2 I, 2 + 2 I}]
