RCP中集成jfreechart

一、下载JFreeChart包

1.http://www.jfree.org/jfreechart/ 

 

开发最小依赖包：

jcommon-1.0.10.jar

jfreechart-1.0.6.jar

jfreechart-1.0.6-swt.jar

 

二、View代码如下：

 

 

package edu.bjtu.port.pieceWage.ui;

import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.Font;

import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.ui.part.ViewPart;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PiePlot3D;
import org.jfree.chart.title.TextTitle;
import org.jfree.data.general.DefaultPieDataset;
import org.jfree.data.general.PieDataset;
import org.jfree.experimental.chart.swt.ChartComposite;
import org.jfree.ui.RectangleInsets;
import org.jport.component.rcp.interfaces.ITableEntity;

public class PieView extends ViewPart {
	private String titleStr = "" ;
	
	public PieView() {
		super();
	}

	protected PieDataset createDataset() {

		DefaultPieDataset defaultpiedataset = new DefaultPieDataset();
		defaultpiedataset.setValue("管理人员", 10.02D);
		defaultpiedataset.setValue("市场人员", 20.23D);
		defaultpiedataset.setValue("开发人员", 60.02D);
		defaultpiedataset.setValue("OEM人员", 10.02D);
		defaultpiedataset.setValue("其他人员", 5.11D);
		return defaultpiedataset;

	}

	/**
	 * Creates a chart.
	 * @param dataset the dataset.
	 * @return A chart.
	 */

	protected JFreeChart createChart(PieDataset dataset) {
		JFreeChart chart = ChartFactory.createPieChart3D("", dataset, true,
				true, true);
		// 设置图片的背景色
		chart.setBackgroundPaint(java.awt.Color.white);
		// 设置图片标题的字体和大小
		Font font = new Font("黑体", Font.CENTER_BASELINE, 20);
		TextTitle title = new TextTitle(titleStr);
		title.setFont(font);
		chart.setTitle(title);

		PiePlot3D pie = (PiePlot3D) chart.getPlot();
		pie.setInsets(new RectangleInsets(5, 5, 5, 5));
		// 指定 section 轮廓线的颜色
		pie.setOutlinePaint(java.awt.Color.BLACK);
		// 指定 section 轮廓线的厚度
		pie.setOutlineStroke(new BasicStroke(1));
		// 设置第一个 section 的开始位置，默认是12点钟方向,90度，逆时针
		pie.setStartAngle(90);
		// 指定 section 的色彩
		pie.setSectionPaint(1, new Color(0x99, 0x99, 0xFF));
		pie.setLabelFont(new Font("黑体", Font.BOLD, 12));
		// 指定显示的饼图上圆形还椭圆形。true为圆形，false为椭圆形。默认为false
		pie.setCircular(true);
		// 指定图片的透明度
		pie.setForegroundAlpha(0.5f);
		pie.setLabelGap(0.01);// 间距
		pie.setNoDataMessage("No data available");
		return chart;
	}

	public void createPartControl(Composite parent) {

		JFreeChart chart = createChart(createDataset());
		final ChartComposite frame = new ChartComposite(parent, SWT.NONE,
		chart, true);

	}

	/**
	 * Passing the focus request to the viewer's control.
	 */

	public void setFocus() {

	}

	public String getTitleStr() {
		return titleStr;
	}

	public void setTitleStr(String titleStr) {
		this.titleStr = titleStr;
	}
}

 

效果如下图：

按照你的代码copy在我的eclipse上运行，怎么文字都显示不出来呢？
