ProportionalRendererDefinition Constructor(String,esriUnits,CIMSymbolReference,SymbolShapes,ValueRepresentations)

In This Topic

Creates a ProportionalRendererDefinition.

Syntax

C#
Visual Basic (Declaration)

public ProportionalRendererDefinition( 
   string field,
   esriUnits units,
   CIMSymbolReference symbolFill,
   SymbolShapes proportionalSymbolType,
   ValueRepresentations valueRepresentations
)

Public Function New( _
   ByVal field As String, _
   ByVal units As esriUnits, _
   ByVal symbolFill As CIMSymbolReference, _
   Optional ByVal proportionalSymbolType As SymbolShapes, _
   Optional ByVal valueRepresentations As ValueRepresentations _
)

Parameters

field: Name of the field used in the renderer.
units: The units used in the renderer.
symbolFill: The fill to be used in symbol type set by using proportionalSymbolType.
proportionalSymbolType: (Optional) The symbol type for a proportional renderer. Only symbol type of circle or square is allowed. (default value = Circle)
valueRepresentations: (Optional) The value representation used in a proportional renderer. (default value = Radius)

Remarks

Use this constructor only when the map is in a Projected Coordinate System.

When the map is in a projected coordinated system and Units is set, use this constructor to symbolize features where the value of the feature gets used as the radius or the area of the symbol (depending on valueRepresentations).

Example

Create a True Proportion Renderer

string colorBrewerSchemesName = "ArcGIS Colors";
StyleProjectItem style = Project.Current.GetItems<StyleProjectItem>().First(s => s.Name == colorBrewerSchemesName);
string colorRampName = "Heat Map 4 - Semitransparent";
IList<ColorRampStyleItem> colorRampList = await QueuedTask.Run(() =>
{
  return style.SearchColorRamps(colorRampName);
});
ColorRampStyleItem colorRamp = colorRampList[0];

await QueuedTask.Run(() =>
{
  CIMPointSymbol pointSym = SymbolFactory.Instance.ConstructPointSymbol(ColorFactory.Instance.GreenRGB, 1.0, SimpleMarkerStyle.Circle);
  CIMSymbolReference symbolPointTemplate = pointSym.MakeSymbolReference();

  //Defining proportional renderer where size of symbol will be same as its value in field used in the renderer.
  ProportionalRendererDefinition prDef = new ProportionalRendererDefinition("POPULATION", esriUnits.esriMeters, symbolPointTemplate, SymbolShapes.Square, ValueRepresentations.Radius);

  FeatureLayer flyr = MapView.Active.Map.Layers[0] as FeatureLayer;
  CIMProportionalRenderer propRndr = flyr.CreateRenderer(prDef) as CIMProportionalRenderer;
  flyr.SetRenderer(propRndr);

});

Requirements

Target Platforms: Windows 11, Windows 10
