StreamMarkers

StreamMarkers

is an option for StreamPlot, ListStreamPlot and related functions that specifies what markers to draw at the field points plotted.

Details

  • The following settings can be used:
  • Noneno markers
    Automaticdefault markers
    "name"named markers name
    {marker1,marker2,…}a list of markers markeri
  • Arrow-like markers that indicate stream flow and the direction include:
  • "Arrow"arrow-shaped marker
    "PinDart"pin-dart-shaped marker
    "Dart"dart-shaped marker
    "CircleArrow"circle with an arrow on its diagonal
  • Additional markers that indicate the stream flow and the direction include:
  • "Dot"line segment with a dot as its arrowhead
    "DotArrow"arrow with a dot at the tail
    "Pointer"pointer-shaped marker
    "BackwardPointer"pointer-shaped marker pointing backward
    "Drop"drop-shaped marker
    "Paddle"paddle with flat end in the field direction
  • General oriented markers that indicate stream flow slope include:
  • "Box"a tight bounding box
    "Segment"line segment
    "DoubleDart"double-ended dart
    "ArrowArrow"double-ended arrow
    "DotDot"line segment with dots at either end
    "BarDot"undirected bar with a dot at its center
    "Spindle"spindle-shaped marker along the field direction
    "Toothpick"toothpick-shaped marker

Basic Examples  (5)

Use arrows as default markers:

Wolfram Language code: StreamPlot[{{x + y, -x + y}}, {x, -2, 2}, {y, -2, 2}]

No markers:

Wolfram Language code: StreamPlot[{{x + y, -x + y}}, {x, -2, 2}, {y, -2, 2}, StreamMarkers -> None]

Use named markers:

Wolfram Language code: StreamPlot[{{x + y, -x + y}}, {x, -2, 2}, {y, -2, 2}, StreamMarkers -> "Drop"]

Use a different type of marker for each field:

Wolfram Language code: StreamPlot[{{x, y}, {y, -x}}, {x, -2, 2}, {y, -2, 2}, StreamMarkers -> {"PinDart", "Dart"}]

Scope  (9)

Use arrows, pin darts or darts to indicate the direction of the flow:

Wolfram Language code: Table[StreamPlot[{x + y, -x + y}, {x, -2, 2}, {y, -2, 2}, ImageSize -> 150, PlotLabel -> sm, StreamMarkers -> sm], {sm, {"Arrow", "PinDart", "Dart"}}]

Use markers with circles or disks at one end and arrows at the other to indicate the direction of the flow:

Wolfram Language code: Table[StreamPlot[{x + y, -x + y}, {x, -2, 2}, {y, -2, 2}, ImageSize -> 150, PlotLabel -> sm, StreamMarkers -> sm], {sm, {"CircleArrow", "DotArrow"}}]

Use forward or backward pointers:

Wolfram Language code: Table[StreamPlot[{x + y, -x + y}, {x, -2, 2}, {y, -2, 2}, ImageSize -> 150, PlotLabel -> sm, StreamMarkers -> sm], {sm, {"Pointer", "BackwardPointer"}}]

Use use line segments to indicate the flow:

Wolfram Language code: StreamPlot[{x + y, -x + y}, {x, -2, 2}, {y, -2, 2}, StreamMarkers -> "Segment"]

Use spindles or toothpicks to indicate the flow:

Wolfram Language code: Table[StreamPlot[{x + y, -x + y}, {x, -2, 2}, {y, -2, 2}, ImageSize -> 150, PlotLabel -> sm, StreamMarkers -> sm], {sm, {"Spindle", "Toothpick"}}]

Use drops or paddles to indicate the flow:

Wolfram Language code: Table[StreamPlot[{x + y, -x + y}, {x, -2, 2}, {y, -2, 2}, ImageSize -> 150, PlotLabel -> sm, StreamMarkers -> sm], {sm, {"Drop", "Paddle"}}]

Use double-ended markers to indicate the flow:

Wolfram Language code: Table[StreamPlot[{x + y, -x + y}, {x, -2, 2}, {y, -2, 2}, ImageSize -> 150, PlotLabel -> sm, StreamMarkers -> sm], {sm, {"DoubleDart", "ArrowArrow", "DotDot"}}]

Use other markers to indicate the flow:

Wolfram Language code: Table[StreamPlot[{x + y, -x + y}, {x, -2, 2}, {y, -2, 2}, ImageSize -> 150, PlotLabel -> sm, StreamMarkers -> sm], {sm, {"Dot", "Box", "BarDot"}}]

Markers are used cyclically:

Wolfram Language code: StreamPlot[{{x, 0}, {x, y}, {0, y}}, {x, -2, 2}, {y, -2, 2}, PlotLegends -> "Expressions", StreamColorFunction -> None, StreamMarkers -> {"Segment", "Dart"}]
