Flex在地圖上繪製TextSymbol標註

var gra:Graphic=new Graphic();
gra.geometry=graphicnew.geometry.extent.center;//獲取地圖中心
var content:String="標註XXX";
var tSymbol:TextSymbol = new TextSymbol(content);
tSymbol.textFormat = new TextFormat();

tSymbol.border = false;
tSymbol.placement=InfoPlacement.BOTTOM;
tSymbol.yoffset=0;
tSymbol.xoffset=0;

gra.symbol=tSymbol;
