Properties

Property Details
attributeField Name of the feature attribute field that contains the data value.
flowRepresentation Sets the flow direction of the data.
Valid values:
  • flow_from
  • flow_to
inputUnit Input unit for Magnitude.
Valid values:
  • esriFeetPerSecond
  • esriKilometersPerHour
  • esriKnots
  • esriMetersPerSecond
  • esriMilesPerHour
outputUnit Output unit for Magnitude.
Valid values:
  • esriFeetPerSecond
  • esriKilometersPerHour
  • esriKnots
  • esriMetersPerSecond
  • esriMilesPerHour
rotationType String value which controls the origin and direction of rotation on point features. If the rotationType is defined as arithmetic, the symbol is rotated from East in a counter-clockwise direction where East is the 0 degree axis. If the rotationType is defined as geographic, the symbol is rotated from North in a clockwise direction where North is the 0 degree axis.
Valid values:
  • arithmetic
  • geographic
style A predefined style.
Valid values: beaufort_ft, beaufort_km, beaufort_kn, beaufort_m, beaufort_mi, classified_arrow, ocean_current_kn, ocean_current_m, simple_scalar, single_arrow, wind_speed
symbolTileSize Determines the density of the symbols. Larger tile size, fewer symbols appear in the display. The VectorFieldRenderer draws one symbol within a defined tile size (in pixels). The default is 50 pixels.
type Specifies the type of renderer used.
Valid value of this property vectorField
visualVariables[] An array of objects used to set rendering properties.
