十万火急！c#winform，水晶报表中的图表纵轴显示的值始终为1
c# winform项目。在水晶报表中插入了一个图表，水平轴显示正确，但是纵轴的柱形图的值始终为1，每个柱形图显示的始终是一条平行线，是哪个地方没设置好吗？？？数据绑定 代码：
string sql = "select lenth_degree,sum(weight) as sumweight from checkinfo group by lenth_degree";
string sqlcon = db.getconnstr();
SqlConnection conn = new SqlConnection(sqlcon);
conn.Open();
SqlDataAdapter da = new SqlDataAdapter(sql, sqlcon);
DataSet2 ds1 = new DataSet2();
da.Fill(ds1, "DataTable1");
if (ds1.Tables["DataTable1"].Rows.Count == 0)
{
MessageBox.Show("错误！");
this.Close();
}
else
{
CrystalReport2 cr1 = new CrystalReport2();
cr1.SetDataSource(ds1.Tables["DataTable1"]);
this.crystalReportViewer1.ReportSource = cr1;
this.crystalReportViewer1.RefreshReport();

}
还有看看你的xsc和xsd文件写对没有
补充：.NET技术 , C#
