Legend for CartographicLineSymbol

Ganael_Jatteau

Hi,

I have a map with some CartographicLineSymbol on a graphic layer and I'm trying to build a legend.

I tried 2 solutions to draw a line symbol into an UIComponent but none of them works.

Solution 1:

var uic:UIComponent = symbol.createSwatch(20,15);

Solution 2:

var uic:UIComponent = new UIComponent();
uic.width = 20;
uic.height = 15;
var polyLine:Polyline = new Polyline();
var p1:MapPoint = new MapPoint(0,0);
var p2:MapPoint = new MapPoint(15,0);
var path:Array = new Array(p1,p2);
polyLine.addPath(path);
symbol.draw(uic, polyLine, null, this._map);

The line symbol has a width, a color. Any idea how to solve that problem?

Thanks!

Ganael,

    Most cartographic lines use composite symbols and the documentation for the createswatch states

Creates a swatch for a symbol which can be used in a legend. Swatches only work with symbols which are supported in the FeatureService, i.e., swatches are not supported for CompositeSymbol, InfoSymbol and TextSymbol.

as far as it not working for the Symbol.draw method I don't know why that is not working.
