ciao a tutti! ho un grafico fatto con JFreeChart, l'asse delle X è il tempo, io adesso lo visualizzo in secondi ma vorrei cambiarlo in HH:mm:ss è possibile?
vi lascio il codice

codice:
/**
     * Plots settigns angles
     * @return 
     */
    public JPanel PlotAngles(){
        DefaultXYDataset DS_Heel = new DefaultXYDataset();
        DS_Heel.addSeries("\u03D5", new double[][] {Time, this.Heel});
        DefaultXYDataset DS_Trim = new DefaultXYDataset();
        DS_Trim.addSeries("\u03B8", new double[][] {Time, this.Trim});
        DefaultXYDataset DS_Tm = new DefaultXYDataset();
        DS_Tm.addSeries("Tm",     new double[][] {Time, this.Tm});
        DefaultXYDataset DS_GM = new DefaultXYDataset();
        DS_GM.addSeries("GM",     new double[][] {Time, this.GM});      
        
        this.Plot_Settings = ChartFactory.createXYLineChart(
