java水泡,JAVA

用javafx实现一个bubblechart泡泡图，具体代码与解释如下：

好看的运行结果为：

1.简单的bubblechart:

package company;

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.chart.BubbleChart;

import javafx.scene.chart.NumberAxis;

import javafx.scene.chart.XYChart;

import javafx.stage.Stage;

public class BubbleChartSample extends Application {

@Override public void start(Stage stage) {

stage.setTitle("Bubble Chart Sample");

final NumberAxis xAxis = new NumberAxis(1, 53, 4);

final NumberAxis yAxis = new NumberAxis(0, 80, 10);

final BubbleChart blc = new

BubbleChart(xAxis,yAxis);

xAxis.setLabel("Time Line");

yAxis.setLabel("Sample Size");

blc.setTitle("Sample Content And Relationship");

XYChart.Series series1 = new XYChart.Series();

series1.setName("Sample 1");

series1.getData().add(new XYChart.Data(3, 35));

series1.getData().add(new XYChart.Data(12, 60));

series1.getData().add(new XYChart.Data(15, 15));

series1.getData().add(new XYChart.Data(22, 30));

series1.getData().add(new XYChart.Data(28, 20));

series1.getData().add(new XYChart.Data(35, 41));

series1.getData().add(new XYChart.Data(42, 17));

series1.getData().add(new XYChart.Data(49, 30));

XYChart.Series series2 = new XYChart.Series();

series2.setName("Sample 2");

series2.getData().add(new XYChart.Data(8, 15));

series2.getData().add(new XYChart.Data(13, 23));

series2.getData().add(new XYChart.Data(15, 45));

series2.getData().add(new XYChart.Data(24, 30));

series2.getData().add(new XYChart.Data(38, 78));

series2.getData().add(new XYChart.Data(40, 41));

series2.getData().add(new XYChart.Data(45, 57));

series2.getData().add(new XYChart.Data(47, 23));

yAxis.setTickLabelFormatter(new NumberAxis.DefaultFormatter(yAxis,"¥",null));

Scene scene = new Scene(blc);

blc.getData().addAll(series1, series2);

stage.setScene(scene);

stage.show();

}

public static void main(String[] args) {

launch(args);

}

}

运行结果为：

2.有交集的bubblechart:

如果需要绘制有覆盖部分的或者有交集的bubblechart那么就可以按照如下实现：

package company;

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.chart.BubbleChart;

import javafx.scene.chart.NumberAxis;

import javafx.scene.chart.XYChart;

import javafx.stage.Stage;

public class BubbleChartSample extends Application {

@Override public void start(Stage stage) {

stage.setTitle("Bubble Chart Sample");

final NumberAxis xAxis = new NumberAxis(1, 53, 4);

final NumberAxis yAxis = new NumberAxis(0, 80, 10);

final BubbleChart blc = new

BubbleChart(xAxis,yAxis);

xAxis.setLabel("Time Line");

yAxis.setLabel("Sample Size");

blc.setTitle("Sample Content And Relationship");

XYChart.Series series1 = new XYChart.Series();

series1.setName("Sample 1");

series1.getData().add(new XYChart.Data(3, 35, 2));

series1.getData().add(new XYChart.Data(12, 60, 1.8));

series1.getData().add(new XYChart.Data(15, 15, 7));

series1.getData().add(new XYChart.Data(22, 30, 2.5));

series1.getData().add(new XYChart.Data(28, 20, 1));

series1.getData().add(new XYChart.Data(35, 41, 5.5));

series1.getData().add(new XYChart.Data(42, 17, 9));

series1.getData().add(new XYChart.Data(49, 30, 1.8));

XYChart.Series series2 = new XYChart.Series();

series2.setName("Sample 2");

series2.getData().add(new XYChart.Data(8, 15, 2));

series2.getData().add(new XYChart.Data(13, 23, 1));

series2.getData().add(new XYChart.Data(15, 45, 3));

series2.getData().add(new XYChart.Data(24, 30, 4.5));

series2.getData().add(new XYChart.Data(38, 78, 1));

series2.getData().add(new XYChart.Data(40, 41, 7.5));

series2.getData().add(new XYChart.Data(45, 57, 2));

series2.getData().add(new XYChart.Data(47, 23, 3.8));

Scene scene = new Scene(blc);

blc.getData().addAll(series1, series2);

stage.setScene(scene);

stage.show();

}

public static void main(String[] args) {

launch(args);

}

}

运行结果为：
