This sample is for generating the layout dynamically when the number of series is unknown.

●Script
value = number of series
dynamicLayout = "<Line2DSeries displayName='";
for(i ; i < value ; ++i){
	dynamicLayout += 
		(i + "th" + dataField[i] + "' yField='" + dataField[i] + "' form='curve'/>");
if(i < value - 1)
	dynamicLayout += "<Line2DSeries displayName='";
}
