for(int i =0;i<var.length;i++)
{
 renderer.setLabelGenerator(new LabelGenerator(var[i]));
 renderer.setItemLabelFont(new Font("Serif", Font.PLAIN, 20));

 renderer.setSeriesItemLabelsVisible(0, false);
 renderer.setSeriesItemLabelsVisible(1, true);

static class LabelGenerator1 implements CategoryLabelGenerator 
	{
		public float var;
		public LabelGenerator1(float var){
			this.var = var;
		//	ETHLogger.log( "var ---->" + var);
		}
