RegionFillingStyle

is an option for plotting functions that specifies the style for the filled region over which the plot is being drawn.

Details

  • RegionFillingStyle is typically used for plots that contain discrete elements, to better show the full region of the plot.
  • The region being styled may come from a variable specification, RegionFunction or a combination of sources.
  • The following settings can be used:
  • Automaticautomatically style the filled region
    Noneomit the filled region
    styledraw with specified graphics directives
  • With RegionFillingStyle->Automatic, regions that completely fill the plot will generally not be drawn.

Basic Examples  (2)

Automatically style the plotted region:

Wolfram Language code: VectorPlot[{y - x, x y}, {x, y}∈Disk[{0, 0}, 1], RegionFillingStyle -> Automatic]

Omit the filled region:

Wolfram Language code: VectorPlot[{y - x, x y}, {x, y}∈Disk[{0, 0}, 1], RegionFillingStyle -> None]

Scope  (3)

Use gray to fill the region:

Wolfram Language code: VectorPlot[{y - x, x y}, {x, y}∈Disk[{0, 0}, 1], RegionFillingStyle -> Gray]

Style the region from a region function:

Wolfram Language code: VectorPlot[{y - x, x y}, {x, -1, 1}, {y, -1, 1}, RegionFillingStyle -> Automatic, RegionFunction -> (# ^ 2 + #2 ^ 2 < 1&)]

By default, the filling is not shown for full regions:

Wolfram Language code: VectorPlot[{y - x, x y}, {x, -1, 1}, {y, -1, 1}, RegionFillingStyle -> Automatic]

Specify an explicit filling style:

Wolfram Language code: VectorPlot[{y - x, x y}, {x, -1, 1}, {y, -1, 1}, RegionFillingStyle -> Gray]
