最近做了一些关于图表方面的开发工作，现把这些开发过程记录一下，就算是留给自己看吧，估计百度也搜不到，我是用Swing开发的。哈哈，没有关系写着玩！
上带码前，先看看我做的效果如何，截图如下：
以上是相同查询条件下，所展示的不同的图表，先看看不同的图表的相关属性设置吧！上代码，对了，还可以导出图片的！

}柱形图，每个柱子的颜色是不同的，为了实现这效果，还是写了一段代码，有继承关系，如下：
public class CustomRenderer extends org.jfree.chart.renderer.category.BarRenderer {
/**
*
*/
private static final long serialVersionUID = 784630226449158436L;
private Paint[] colors;
//初始化柱子颜色
private String[] colorValues = { "#87CEFA", "#B0C4DE", "#8470FF", "#8B4513", "#FF00FF", "#FFF5EE" };
public CustomRenderer() {
colors = new Paint[colorValues.length];
for (int i = 0; i < colorValues.length; i++) {
colors[i] = Color.decode(colorValues[i]);
}
}
//每根柱子以初始化的颜色不断轮循
public Paint getItemPaint(int i, int j) {
return colors[j % colors.length];
}
}这样就实现了每个柱子的颜色不同，我将柱子的颜色设置和图表属性的设置写在同一个类里了，下面再来看看后台所支持的数据
当然了，数据表还有外键，现在就不多说了，结构已经给了，下面看看后台查询，上代码：
public Map<Object, Number> statMaterialChecks(int type, Equipment parent, Date from, Date to, String normalFlag,
