关键字: jfreechart

public class 总结 {
	public static void main(String[] args) {
		JFreeChart jfreechart = null;
		
		//获得标题title.getText()
		TextTitle title = jfreechart.getTitle();
		
		//设置标题
		jfreechart.setTitle("A Chart Title");
		
		//设置标题的位置
		jfreechart.getTitle().setPosition(RectangleEdge.BOTTOM);
		
		//当然了还可以设置副标题
		TextTitle subtitle1 = new TextTitle("A Subtitle");
		jfreechart.addSubtitle(subtitle1);
		
		//获得副标题,可以有很多副标题,这是获得第0个
		Title subtitle = jfreechart.getSubtitle(0);
		
		//设置背景颜色
		jfreechart.setBackgroundPaint(Color.blue);
		
		//当然还可以设置多种背影颜色
		//表示在某个坐标之后是什么颜色
		Paint p = new GradientPaint(0, 0, Color.white, 1000, 0, Color.green);		
		jfreechart.setBackgroundPaint(p);
		
		//设置背景图片LOG
		jfreechart.setBackgroundImage(JFreeChart.INFO.getLogo());
		
		//设置背景图片的位置,这个没有试过
		jfreechart.setBackgroundImageAlignment(Align.TOP_LEFT);
		
		//Plot Attributes(共有的)
		//Plot(饼状图,)
		Plot plot1 = jfreechart.getPlot();
		
		//Plot(柱状图,)
		CategoryPlot plot2 = jfreechart.getCategoryPlot();
		
		//Plot(XY坐标图)
		XYPlot plot3 = jfreechart.getXYPlot();
		
		//设置背影颜色(是图象的)(其它形状同理)
		plot1.setBackgroundPaint(Color.white);
		//设置背景颜色
		plot1.setBackgroundImage(JFreeChart.INFO.getLogo());
		
		//Axis Attributes(X和Y上面的,轴对象,分为X轴Y轴)
		// get an axis reference...
		CategoryPlot plot = jfreechart.getCategoryPlot();
		
		//获得X轴对象
		CategoryAxis domainAxis = plot.getDomainAxis();
		//获得Y轴对象
		ValueAxis rangeAxis = plot.getRangeAxis();
		
		//change axis properties...改变属性
		domainAxis.setLabel("Categories");
		domainAxis.setLabelFont(new Font("宋体", Font.CENTER_BASELINE, 20));
		
		//设置X轴字体,Y轴同样
		domainAxis.setTickLabelFont(new Font("宋体", Font.CENTER_BASELINE, 20));
