How to plot multiple series with javafx line chart which is in array list

Question

There is no error but there is an issue with the plot am not getting the correct line chart plot, I want parameters in the x-axis and values in the y-axis but I have 3 engines a

Answer 1

Change the generateChart of performance class

public void generateChart() {
    for (int i = 0; i < engines.size(); i++) {
        XYChart.Series series = new XYChart.Series();
        series.setName(engines.get(i).toString());
        for (int j = 0; j < parameters.size(); j++) {
            series.getData().add(new XYChart.Data(parameters.get(j).toString(), param.get(i).get(j)));
        }
        lineChart.getData().add(series);
    }
    System.out.println(lineChart);
}

And Use the class from the start method of NewFXMain class like below and remove the for loop

performance performvalues = new performance(lineChart, parameters, finalValue, engines);
performvalues.generateChart();

Note : Always keep the class name CamelCase
