Google Maps APIとGeoJSON

GeoJSONとGoogle Maps APIに問題があります。私はとMultiLineStringの...
1）各行持つそれ自身の色と
2）をプロットするにはどうすればよい
各行持つそれ自身の性質と
3）各ラインはクリック可能、それはだと情報ウィンドウを表示する必要がありますプロパティ

サンプルJavascriptを：ユーザがロードやマップ内のキーをアンロードすることができますよう
Google Maps APIとGeoJSON

var dataGEOJSON=[]; 
function LoadMyGEOJSON(key) 
{ 
    dataGEOJSON[key] = new google.maps.Data(); 
    dataGEOJSON[key].loadGeoJson('GetLatLngGEOJSON.aspx?key=' + key); 
    dataGEOJSON[key].setMap(map); 
}

アレイの理由は、私は彼らがロードされたキーを追跡することができる方法です。 t後継ユーザーインターフェース。
