represents a custom marker at position pos.

ImageMarker[{pos1,pos2,},]
represents multiple marker positions posi.

DetailsDetails

  • The following marker specifications can be used:
  • imagean Image object
    graphicsa Graphics object
    exprany arbitrary expression expr
    "shape"a known named marker "shape"
  • Supported known shapes "shape" include:

  • Positions posi can be specified by:
  • {x,y}ordinary coordinates in a plot
    Scaled[{x,y},]scaled coordinates from 0 to 1
    ImageScaled[{x,y},]scaled coordinates from 0 to 1 across a whole image
