Hello
suppose a1 and b1 r the arraylist which contains data for x and Y axis

Code: Select all

for(int i=0;i<a1.size();i++)
        {
           
            double d= Double.parseDouble(a1.get(i).toString());
            double d1= Double.parseDouble(b1.get(i).toString());
            
           series1.add(d, d1);
        }
XYSeriesCollection dataset = new XYSeriesCollection();
dataset.addSeries(series1);
