ixyplot控件

iXYPlotX1.Channel(0).AddNull l单独使用和

iXYPlotX1.Channel(0).AddNull、iXYPlotX1.RemoveAllChannels、iXYPlotX1.AddChannel三条语句配合使用效果是不一样的。区别在哪里？自己动手试一下吧

 

1、配合使用Dim k As SingleDim s(5) As SingleDim i, j As IntegerDim lngDispBegin As LongDim lngDispEnd As Longs(1) = 5s(2) = 7s(3) = 10s(4) = 8s(5) = 12iXYPlotX1.RemoveAllChannelsiXYPlotX1.AddChanneliXYPlotX1.Channel(0).TraceLineStyle = iplsDash For j = 1 To 1 For i = 1 To 5 iXYPlotX1.Channel(0).AddXY i, s(i) s(i) = s(i) + 5 Next iXYPlotX1.Channel(0).AddNull Next

 

绘图如下：

 

 

2、单独使用Dim k As SingleDim s(5) As SingleDim i, j As IntegerDim lngDispBegin As LongDim lngDispEnd As Longs(1) = 5s(2) = 7s(3) = 10s(4) = 8s(5) = 12iXYPlotX1.Channel(0).TraceLineStyle = iplsDash For j = 1 To 1 For i = 1 To 5 iXYPlotX1.Channel(0).AddXY i, s(i) s(i) = s(i) + 5 Next iXYPlotX1.Channel(0).AddNull Next

 

 

 

注意：iplsDash和iplsDot仅仅在TraceLineWidth = 1时候有效。

当TraceLineWidth》1时，iplsDash和iplsDot都默认成为iplsSolid
