Question

mschart饼图绑定数据源问题

DataTable dt = CStatsReport.StatsGDZXMRSJQD_TXH(dtDateStart, dtDateEnd, szJBH, ref objDB);
chrCount.DataSource = dt;
//Series series = new Series("series4");
//series.ChartType = SeriesChartType.Pie;
//series.Legend = "Legend1";
chrCount.ChartAreas[0].Area3DStyle.Enable3D = true;
chrCount.Series["Series1"].IsValueShownAsLabel = true;
chrCount.Series["Series1"].CustomProperties = "DoughnutRadius=25, PieDrawingStyle=Concave, CollectedLabel=Other, MinimumRelativePieSize=20";
chrCount.Series["Series1"].Label = "#PERCENT{P1}";
chrCount.Series["Series1"].BackGradientStyle = GradientStyle.None;
for (int i = 0; i < dt.Rows.Count; i++)
{
chrCount.Series["Series1"].Points.AddXY(dt.Rows[i]["szDKZL"], dt.Rows[i]["dDKJE"].ToString());
chrCount.Series["Series1"].ToolTip = dt.Rows[i]["dDKJE"].ToString();
//string ses = "Series" + (i + 1).ToString();
chrCount.Series["Series1"].LegendText = dt.Rows[i]["szDKZL"].ToString() + ":" + dt.Rows[i]["nCount"].ToString() + "笔" + dt.Rows[i]["dDKJE"].ToString() + "(万元)";
}

怎么图列老是显示最后一个贷款种类呢，麻烦大虾看看问题处在哪里

Answer 1

在循环中修改：

//将这行注释打开
string ses = "Series" + (i + 1).ToString();

chrCount.Series[ses].LegendText = i;

看看是否有效果?
