JFreeChart折线图横坐标怎么显示我传进去的数值

oscar2006 2010-07-19 02:21:22

我画了一个双Y轴的折线图
我传进去的横坐标是1，2，3，4，5，6，7，8，9，10
但是画出来之后变成了1.0，1.5，2.0........9.0，9.5,10.0;
我想知道怎么让他只显示我传进去的（1，2，3，4，5，6，7，8，9，10）
代码如下：



public class LineMode {

	String title;

	String xname;

	String y1name;

	String y2name;

	String l1name;

	String l2name;

	int x,y;

	XYSeriesCollection ld1,ld2;

	public LineMode(String title,String xname,String y1name,String y2name,int x,int y){

		this.title=title;

		this.xname=xname;

		this.y1name=y1name;

		this.y2name=y2name;

		this.x=x;

		this.y=y;

	}

	public void setLname(String l1,String l2){

		this.l1name=l1;

		this.l2name=l2;

	}

	public void createDataset1(int number,double[] data,int[] date){

		XYSeries xyseries = new XYSeries(l1name);

		for(int i=0;i<number;i++){

			xyseries.add(date[i], data[i]);

		}

		ld1 = new XYSeriesCollection();

		ld1.addSeries(xyseries);

	}

	public void createDataset2(int number,double[] data,int[] date){

		XYSeries xyseries = new XYSeries(l2name);

		for(int i=0;i<number;i++){

			xyseries.add(date[i], data[i]);

		}

		ld2 = new XYSeriesCollection();

		ld2.addSeries(xyseries);

	}

	public JFreeChart draw(){

		XYDataset xydataset = ld1;

		JFreeChart jfreechart = ChartFactory.createXYLineChart(title, xname, y1name, xydataset, PlotOrientation.VERTICAL, true, true, false);

		XYPlot xyplot = (XYPlot)jfreechart.getPlot();

		NumberAxis numberaxis = (NumberAxis)xyplot.getRangeAxis();

		numberaxis.setAutoRangeIncludesZero(false);

		NumberAxis numberaxis1 = new NumberAxis(y2name);

		numberaxis1.setAutoRangeIncludesZero(false);

		xyplot.setRangeAxis(1, numberaxis1);

		xyplot.setDataset(1, ld2);

		xyplot.mapDatasetToRangeAxis(1, 1);

		XYLineAndShapeRenderer xylineandshaperenderer = (XYLineAndShapeRenderer)xyplot.getRenderer();

		

		XYLineAndShapeRenderer xylineandshaperenderer1 = new XYLineAndShapeRenderer(true, true);

		xylineandshaperenderer1.setSeriesPaint(0, Color.black);

		xyplot.setRenderer(1, xylineandshaperenderer1);

		LegendTitle legendtitle = new LegendTitle(xylineandshaperenderer);

		LegendTitle legendtitle1 = new LegendTitle(xylineandshaperenderer1);

		BlockContainer blockcontainer = new BlockContainer(new BorderArrangement());

		blockcontainer.add(legendtitle, RectangleEdge.LEFT);

		blockcontainer.add(legendtitle1, RectangleEdge.RIGHT);

		blockcontainer.add(new EmptyBlock(2000D, 0.0D));

		CompositeTitle compositetitle = new CompositeTitle(blockcontainer);

		compositetitle.setPosition(RectangleEdge.BOTTOM);

		jfreechart.addSubtitle(compositetitle);

		jfreechart.getTitle().setFont(new Font("宋体", Font.BOLD, 15));

		jfreechart.getLegend().setItemFont(new Font("黑体", Font.BOLD, 15));

		ValueAxis domainAxis = xyplot.getDomainAxis();

		domainAxis.setTickLabelFont(new Font("黑体", Font.PLAIN, 11)); 	

                  domainAxis.setLabelFont(new Font("宋体", Font.PLAIN, 12)); 

		NumberAxis numberaxis11 = (NumberAxis) xyplot.getRangeAxis(); 		   

                  numberaxis11.setTickLabelFont(new Font("黑体", Font.PLAIN, 12)); 		  

                  numberaxis11.setLabelFont(new Font("黑体", Font.PLAIN, 12));

		return jfreechart;

	}
