Arrow

Arrow[{pt1,pt2}]

is a graphics primitive that represents an arrow from pt1 to pt2.

Arrow[{pt1,pt2},s]

represents an arrow with its ends set back from pt1 and pt2 by a distance s.

Arrow[{pt1,pt2},{s1,s2}]

sets back by s1 from pt1 and s2 from pt2.

Arrow[curve,…]

represents an arrow following the specified curve.

Details

  • Arrow can be used in both Graphics and Graphics3D (two- and three-dimensional graphics).
  • The following curve specifications can be used in Graphics:
  • Line[…]piecewise line segments
    BezierCurve[…]composite Bezier curve
    BSplineCurve[…]B-spline curve
    JoinedCurve[…]joined curve object
  • The following curve specifications can be used in Graphics3D:
  • Line[…]piecewise line segments
    BezierCurve[…]composite Bezier curve
    BSplineCurve[…]B-spline curve
    Tube[…]tubed curve object
  • Arrow[Line[…]] is equivalent to Arrow[…]. Arrow[Tube[…]] yields a 3D arrow based on a tube.
  • Arrow[{pt1,pt2,…}] represents an arrow whose shaft passes through the sequence of points pti.
  • The positions of points can be specified either in ordinary coordinates as {x,y}, or in scaled coordinates as Scaled[{x,y}] or using ImageScaled or Offset. »
  • The shaft of the arrow consists of a sequence of straight segments joining the specified points.
  • Arrow[{pt1,pt2}] is drawn by default with its tail at pt1 and its head at pt2.
  • The form, orientation, and position of arrowheads can be specified by an Arrowheads directive. »
  • Graphics directives such as RGBColor or Thickness apply to both the shaft and arrowhead elements of an arrow. »
  • You can prevent directives from applying to an arrowhead by including explicit directives within the graphic used to specify the arrowhead.
  • In Arrow[{pt1,pt2},s] the setback distance s is measured in the ordinary coordinate system of the whole graphic, so that the arrow will just touch Disk[pti,s]. »
  • If the whole graphic does not have AspectRatio->Automatic, then a specified arrow setback may correspond to different distances in different directions in the graphic.
