如何設定jfreechart時間序列圖曲線顏色

  chart = ChartFactory.createTimeSeriesChart(......);

XYPlot xyplot=(XYPlot) chart.getPlot();

XYLineAndShapeRenderer xylinerenderer=(XYLineAndShapeRenderer)xyplot.getRenderer();

//以下分別給同一個曲線圖中3條曲線設定顏色,0為第一條1為第二條,......

    xylinerenderer.setSeriesPaint(0, new Color(0, 0 ,255 ));
    xylinerenderer.setSeriesPaint(1, new Color(255 ,215, 0 ));
    xylinerenderer.setSeriesPaint(2, new Color(0, 238, 118));
