Force an update to occur. Default value is false.
Example Version

SetLinkChartLayoutAsync(MapView,KnowledgeLinkChartLayoutAlgorithm,Boolean) Method
Sets the layout algorithm for the link chart map view. This method must be called on the MCT. Use QueuedTask.Run.
Syntax

Parameters

mapView
algorithm
The link chart layout algorithm
forceLayoutUpdate
Force an update to occur. Default value is false.
Exceptions
ExceptionDescription
Map cannot be null.
Map is not a link chart.
This method or property must be called within the lambda passed to QueuedTask.Run.
Example
Get and set the link chart layout
var mv = MapView.Active;

// a MapView can encapsulate a link chart IF it's map
// is of type MapType.LinkChart
var map = mv.Map;
var isLinkChart = map.MapType == MapType.LinkChart;
// or use the following
// var isLinkChart = map.IsLinkChart;

QueuedTask.Run(() =>
{
  if (isLinkChart)
  {
    // get the layout algorithm
    var layoutAlgorithm = mv.GetLinkChartLayout();

    // toggle the value
    if (layoutAlgorithm == KnowledgeLinkChartLayoutAlgorithm.Geographic_Organic_Standard)
      layoutAlgorithm = KnowledgeLinkChartLayoutAlgorithm.Organic_Standard;
    else
      layoutAlgorithm = KnowledgeLinkChartLayoutAlgorithm.Geographic_Organic_Standard;

    // set it
    mv.SetLinkChartLayoutAsync(layoutAlgorithm);

    // OR set it and force a redraw / update
    // await mv.SetLinkChartLayoutAsync(layoutAlgorithm, true);
  }
});
