How to change the TimeSeries and TimeSeriesCollection to XYSeries and XYCollection respectively in java?
Based on this example, this code is for draging the point in the chart. I want to replace TimeSeries object with XYSeries because I dont want the months in X-axis; I want the series of number like Point1, Point2, Point3 and so on, and want the same logic. When replacing with XYSeries I am not getting how to change the logic for XYSeries.

Solution
As both accept an XYDataset and both use an XYLineAndShapeRenderer internally, the essential step is to replace the ChartFactory:
// ChartFactory.createTimeSeriesChart(…);
ChartFactory.createXYLineChart(…);
The remaining changes substitute the XYSeries accessors/mutators and construct the GUI on the event dispatch thread.
