在DynamicReports上创建图表以按年比较销售额

时间：2016-05-07 05:17:45

标签： java mysql jasper-reports dynamic-reports

在图片的图表中，我显示了某些产品销售的double*。

我现在想要的是创建另一个图表，但要比较不同年份的相同销售额和价值。就像在这个链接中找到的那样：http://www.dynamicreports.org/examples/groupchartreport2，但在一个图表中，到目前为止，我无法完成。

感谢您的帮助。

我解决了，问题出在我的query，这是正确的：

String query = "select SUM(value_sale) as sum,COUNT(id_sale) as count,YEAR(date_sale) as year, YEAR(date_sale) as y,id,pro.name "
                + "from sales s "
                + "inner join product pro on pro.id=s.prduct_id "
                + "group by year,name";

这部分更具体：group by year,name。我错过了group by的第二部分。然而，我想对我做这个图表的方式，代码有一些看法。
