我用JFreeChart创建了一个温度计图表,但我想改变温度计中的水银颜色.我怎样才能做到这一点？到目前为止,这是我的代码; 请说明更改此代码的位置:

final DefaultValueDataset dataset = new DefaultValueDataset(new Double(10));

// create the chart...
final ThermometerPlot plot = new ThermometerPlot(dataset);

final JFreeChart chart = new JFreeChart("Thermometer Demo 2",  // chart title
                                        JFreeChart.DEFAULT_TITLE_FONT,
                                        plot,                  // plot
                                        false);                // include legend

chart.setBackgroundPaint(new Color(241,250,224));
plot.setMercuryPaint();
final NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
rangeAxis.setUpperBound(50);
