我使用JFreeChart
创建了一个BoxAndWhiskerRenderer
地块,似乎它会自动创建一种传奇(见附图)。
有没有办法删除此图例的外边框并自定义图例项目中标签的字体?
以下是我的代码示例:
//Get the desired BoxAndWhiskerCategoryDataset from a LinkedHashMap
BoxAndWhiskerCategoryDataset dataset = values.get(b);
//Create X axis
CategoryAxis xAxis = new CategoryAxis();
xAxis.setAxisLineVisible(false);
//Create Y axis
NumberAxis yAxis = new NumberAxis(b.getLabel());
yAxis.setAxisLineVisible(false);
yAxis.setTickLabelFont(FDFont.getFont(12f));
yAxis.setLabelFont(FDFont.getFont());
yAxis.setLabelPaint(FDPalette.secondaryText);
yAxis.setTickLabelPaint(FDPalette.secondaryText);
yAxis.setAutoRangeIncludesZero(false);
//Create renderer
BoxAndWhiskerRenderer renderer = new BoxAndWhiskerRenderer();
int count = 0;
for(Map.Entry<Integer,Color> map : clusterColor.entrySet()){
//Set color for the series (I have a previously created map which links colors and series)
renderer.setSeriesPaint(count,map.getValue());
count++;
}
renderer.setFillBox(true);
renderer.setToolTipGenerator(new BoxAndWhiskerToolTipGenerator());
CategoryPlot plot = new CategoryPlot(dataset, xAxis, yAxis, renderer);
JFreeChart chart = new JFreeChart(plot);
chart.setBackgroundPaint(white);
chart.setBorderVisible(false);
ChartPanel chartPanel = new ChartPanel(chart);
chartPanel.setPreferredSize(new java.awt.Dimension(300, 270));
答案 0 :(得分:2)
如图所示here,最简单的JFreeChart
构造函数默认添加图例。这样做的代码是here;只需替换您想要的框架,颜色和位置。
从此example开始,以下更改会生成如下所示的图表:
private void createChartPanel() {
…
JFreeChart chart = new JFreeChart("BoxAndWhiskerDemo", plot);
LegendTitle legend = chart.getLegend();
legend.setFrame(new LineBorder(Color.white, new BasicStroke(1.0f),
new RectangleInsets(1.0, 1.0, 1.0, 1.0)));
legend.setItemFont(legend.getItemFont().deriveFont(16f));
chartPanel = new ChartPanel(chart);
}
与此默认图例比较:
