open-flash-chart多bar

今天在做项目时需要用到多组bar的比较，以前都是用单个的。突然脑筋转不过弯了，不知道所措。网上搜了老半天也没有结果。

最后只能自己去摸索了。不过最后还算成功了，但是bar.Alpha的值没有设置，所以浪费了我不少时间，还以为一直没有显示出来呢。

原来char默认值是完全透明的啊，以前从来不知道哦。

下面粘出最后实现代码及效果

 

string year = DateTime.Now.Year.ToString();
        string month = DateTime.Now.Month.ToString();
        string strWhere = " cs_year='"+year+"' and cs_month='"+month+"'";//查询条件/   
        PMSTASK.Business.CITCPMS_SQA bSqa = new PMSTASK.Business.CITCPMS_SQA();
        DataTable dt = bSqa.GetChartData(strWhere).Tables[0]; ;

        if (dt.Rows.Count > 0)
        {
            OpenFlashChart.OpenFlashChart chart = new OpenFlashChart.OpenFlashChart();
            chart.Title = new Title("SQA检查报告图");
