ChartDirector常见用法(示例代码)

ChartDirector 常见用法（示例代码）最近在尝试在ChartDirector 里进行坐标的设置，想在这里写写最近最近的学习成果。

下面是我的代码实例，里面就是实现如何在ChartDirector 里进行坐标的设置，代码如下：1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 public void createChart(ChartViewer viewer, int index) {// 这是两组数据，X 和Y 会一一对应生成；多在多纵轴图中使用，横坐标点会自动调整。

double[] dataY0 = { 4.5, 5};Date[] dataX0 = {new GregorianCalendar(1999, 1, 1).getTime(), new GregorianCalendar(2000,8, 6).getTime()};double[] dataY1 = {7, 6.5, 6, 5, 6.5, 7, 6, 5.5, 5,9,8,7,8}; Date[] dataX1 = {new GregorianCalendar(1999, 1, 1).getTime(), new GregorianCalendar(1999, 6, 1).getTime(), new GregorianCalendar(1999,11, 1).getTime(), new GregorianCalendar(1999, 11, 15).getTime(),new GregorianCalendar(1999, 12, 9).getTime(), new GregorianCalendar(2000,2, 3).getTime(), new GregorianCalendar(2000, 7, 13).getTime(),new GregorianCalendar(2001, 4, 5).getTime(), new GregorianCalendar(2001,8, 16).getTime(), new GregorianCalendar(2001,10, 16).getTime(),new GregorianCalendar(2001, 12, 16).getTime(),newGregorianCalendar(2002,2, 16).getTime(),new GregorianCalendar(2002,4, 16).getTime()}; //这是单独的横坐标数据，横坐标会根据数据进行调整，Y 轴会按照顺利一一对应。

Date[] dataX2 = {new GregorianCalendar(1999, 1, 1).getTime(), new36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 GregorianCalendar(1999, 4, 1).getTime(),new GregorianCalendar(1999, 8, 9).getTime(), new GregorianCalendar(2000,1, 1).getTime(),new GregorianCalendar(2000, 4, 1).getTime(),new GregorianCalendar(2001, 8, 1).getTime(),};//创建图形的大小为 500 x 270 pixels, with a pale blue// (e0e0ff) background, black border, 1 pixel 3D border effect and roundedXYChart c = new XYChart(700, 500, 0xe0e0ff, 0x000000, 1); c.setRoundedFrame();// 起点坐标是 (55, 60) ，图形大小是520 x 200 pixels, with whitec.setPlotArea(55, 60, 500, 300, 0xffffff, -1, -1, 0xcccccc, 0xcccccc);// Add a legend box at (55, 32) (top of the chart) with horizontal layout.// Use 9 pts Arial Bold font.
