如何画一个现有的JFreeChart以上spiderchart [英] How to draw a spiderchart above a existing JfreeChart

问题描述

我有一个jfree图，我可以生成每次我运行code。
现在我想覆盖在同一图表上几个蜘蛛图。请帮我该怎么做。

在此之上，我需要使用jfree多加一个蜘蛛图。

下面是我的code做这个图表。

感谢ü提前帮助，并采取努力，看到这一点。

解决方案

  

我要重写在同一图表上几个蛛网图。

它可以帮助检查一个蜘蛛网情节是如何用来显示多元数据。下面的简单的例子只是比较两个意见，每个有五个变量名为 A ..Ë ，随着范围的随机值 1。3 。一次偶然的机会，对于变量的值 B 重合;其余的不同。您可以调整意见的值来看看效果，但结果却逐渐变得为观测值的数量变得更加混乱。您可能要改变一系列的知名度，所建议的这里，或考虑这些的 的替代品。

I have one a jfree chart which I can generate everytime I run the code. Now i want to override few more spider graphs on the same chart. please help me how to do that

Above this i need to add one more spider chart using jfree.

Here is my code for doing this chart.

        Paint p = new GradientPaint(0, 1, bckColor1, 0, 1, bckColor1);
        plot.setSeriesPaint(p);
        JFreeChart chart = new JFreeChart("", plot);
        return chart;
    }


    public static JPanel createDemoPanel()

}

Please help me as soon as possible i need to send this build by tomorrow Thank u in advance for helping and taking efforts to see this.

解决方案

I want to override few more spider graphs on the same chart.

It may help to examine how a spider web plot is used to display multivariate data. The simplified example below compares just two OBSERVATIONS, each having five VARIABLES named A .. E, with random values in the range 1 .. 3. By chance, the values for variable B coincide; the rest differ. You can adjust the value of OBSERVATIONS to see the effect, but the result becomes progressively more muddled as the number of observations grows. You may want to alter series visibility, as suggested here, or consider these alternatives.

import java.awt.EventQueue;
import java.util.Random;
import javax.swing.JPanel;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.SpiderWebPlot;
import org.jfree.data.category.CategoryDataset;
import org.jfree.data.category.DefaultCategoryDataset;
import org.jfree.ui.ApplicationFrame;

/** @see http://stackoverflow.com/a/32885067/230513 */
public class SpiderChart extends ApplicationFrame {

    private static final int OBSERVATIONS = 2;
    private static final int VARIABLES = 5;
    private static final Random r = new Random();

    public SpiderChart(String s) {
        super(s);
        add(createDemoPanel());
    }

    private static CategoryDataset createDataset() {

        DefaultCategoryDataset dataset = new DefaultCategoryDataset();
        for (int i = 1; i <= OBSERVATIONS; i++) {
            String rowKey = "Observation " + i;
            for (int j = 1; j <= VARIABLES; j++) {
                Comparable colKey = Character.valueOf((char)(j+64));
                dataset.addValue(r.nextInt(3) + 1, rowKey, colKey);
            }
        }
        return dataset;
    }

    public static JFreeChart createChart(CategoryDataset dataset) {
        SpiderWebPlot plot = new SpiderWebPlot(dataset);
        JFreeChart chart = new JFreeChart("Test", plot);
        return chart;
    }

    public static JPanel createDemoPanel() {
        JFreeChart jfreechart = createChart(createDataset());
        return new ChartPanel(jfreechart);
    }

    public static void main(String args[]) {
        EventQueue.invokeLater(() -> {
            SpiderChart demo = new SpiderChart("SpiderWebChart");
            demo.pack();
            demo.setDefaultCloseOperation(EXIT_ON_CLOSE);
            demo.setVisible(true);
        });
    }
}
