我想用多个系列绑定不同数据集(dtDev,dtProd,dtQA)的rad图表,可以告诉我如何编码?
我们有三个日期dtDev,dtProd,dtQA,只是盲目的例子。
请healp,谢谢你!
monthlyradchartcontrole.Clear()
Dim dtDev as dataset = nothing
dtDev = obj.datareturn(parameters)
monthlyradchartcontrole.DataSource = dtDev
monthlyradchartcontrole.DataBind()
monthlyradchartcontrole.Series(0).DataXColumn = "ScheduledStartDate"
monthlyradchartcontrole.Series(0).DataYColumn = "ChamberUtilization"
monthlyradchartcontrole.PlotArea.XAxis.AxisLabel.TextBlock.Text = monthlyXaxislableName
monthlyradchartcontrole.PlotArea.XAxis.AxisLabel.Visible = True
monthlyradchartcontrole.PlotArea.XAxis.AxisLabel.TextBlock.Appearance.TextProperties.Color = System.Drawing.Color.Red
monthlyradchartcontrole.PlotArea.XAxis.AxisLabel.TextBlock.Appearance.Position.Auto = True
monthlyradchartcontrole.PlotArea.YAxis.AxisLabel.Visible = True
monthlyradchartcontrole.PlotArea.YAxis.AxisLabel.TextBlock.Text = monthlyYaxislableName
monthlyradchartcontrole.PlotArea.YAxis.AxisLabel.TextBlock.Appearance.TextProperties.Color = System.Drawing.Color.Red
monthlyradchartcontrole.PlotArea.YAxis.AxisLabel.TextBlock.Appearance.Position.Auto = True
monthlyradchartcontrole.Legend.Visible = False
谢谢,

您的陈述是将T1和T2中的列彼此相邻:
T1.a, T1.b, T2.a, T2.b
我认为不是你想要的。你可能想要:
a, b
所以你应该使用一个联盟:
select T1.a, T1.b
from T1
union select T1.a, T1.b
from T2
into T3
如果您确实希望将多个表的列插入另一个表中,请尝试以下方法:
select T1.a, T2.b
from T1 inner join T2 on T1.ClientID = T2.ClientID
into T3
