Force map labels horizontal

Is there a way to force labels added to a map to appear horizontal?

return QueuedTask.Run(() => { var lyr = featureLayer; var lyrDefn = lyr.GetDefinition() as CIMFeatureLayer; CIMTextSymbol textSymbol = SymbolFactory.Instance.ConstructTextSymbol(ColorFactory.Instance.BlackRGB, 12, "Arial", "Bold"); textSymbol.Callout = CreateCIMCallout(); //Create the new label class and initialize props var newLabelClass = new CIMLabelClass { ExpressionEngine = LabelExpressionEngine.Arcade, Expression = "$feature.id", Visibility = true, TextSymbol = textSymbol.MakeSymbolReference(), Name = "XX", }; var maplexLabelPlacementProps = new CIMMaplexLabelPlacementProperties { ThinDuplicateLabels = true, FeatureType = LabelFeatureType.Polygon, }; var standardLabelPlacementProps = new CIMStandardLabelPlacementProperties { FeatureType = LabelFeatureType.Polygon, }; newLabelClass.MaplexLabelPlacementProperties = maplexLabelPlacementProps; var lyrsLabelsClasses = lyrDefn.LabelClasses.ToList(); lyrsLabelsClasses.Clear(); lyrsLabelsClasses.Add(newLabelClass); lyrDefn.LabelClasses = lyrsLabelsClasses.ToArray(); //Set the labelClasses back lyr.SetDefinition(lyrDefn); //set the layer's definition; featureLayer.SetLabelVisibility(true); });

Hi,

Set additional property to maplexLabelPlacementProps:

var maplexLabelPlacementProps = new CIMMaplexLabelPlacementProperties { ThinDuplicateLabels = true, FeatureType = LabelFeatureType.Polygon, PolygonPlacementMethod = MaplexPolygonPlacementMethod.HorizontalInPolygon };

I would recommend you use CIM Viewer for that kind of investigation

Works!

Will look into the viewer 👍
