Chart控件作图，怎么动态添加Series与ChartAreas

using System.Web.UI.DataVisualization.Charting

private void NewChart()

{

Chart Chart1=new Chart1

//设置位置

Chart .Location = new System.Drawing.Point(83, 120)

DataTable dt = CreateDataTable()

//设置图表的数据源

Chart1.DataSource = dt

//设置图表Y轴对应项

Chart1.Series[0].YValueMembers = "Time"

//设置图表X轴对应项

Chart1.Series[0].XValueMember = "Date"

//绑定数据

Chart1.DataBind()

}

//创建表

private DataTable CreateDataTable()

{

DataTable dt = new DataTable()

//添加列

dt.Columns.Add("Date")

dt.Columns.Add("Time")

DataRow dr

//添加行dr = dt.NewRow()

dr["Date"] = "2010-1-1"

dr["Time"] = "10:12"

dt.Rows.Add(dr)

dr = dt.NewRow()

dr["Date"] = "2010-1-2"

dr["Time"] = "10:11"

dt.Rows.Add(dr)

return dt

}

Chart控件能成功加载到Panel中，加载进去后图表显示不出来。我找到问题所在了，还必须给Chart对象添加一个ChartArea对象才行，这样就能正常显示了。代码如下： //统计结果柱状图显示 Chart chartColumn = new Chart()chartColumn.ID = "chartColumn" + (i + 1).ToString()Series series = new Series()series.ChartType = SeriesChartType.ColumnchartColumn.Series.Add(series)ChartArea charArea = new ChartArea()charArea.Area3DStyle.LightStyle = LightStyle.RealisticchartColumn.ChartAreas.Add(charArea)chartColumn.DataSource = ds.Tables[i]chartColumn.Series[0].YValueMembers = "selectedNum"chartColumn.Series[0].XValueMember = "optionDescription"chartColumn.DataBind()pnlQuestion.Controls.Add(chartColumn)谢谢大家的帮助，问题已解决，结贴给分了。 查看原帖>>
