VB6 里MSCHART 画两条曲线
一条曲线的代码如下：
Dim MyData(12, 1) As Double
'-----x轴坐标值-----Y轴坐标值----------
MyData(0, 0) = 0: MyData(0, 1) = 180 '本句代表了：第一点数据的X轴坐标为0，Y轴坐标为180
MyData(1, 0) = 1: MyData(1, 1) = 960
MyData(2, 0) = 2: MyData(2, 1) = 60
MyData(3, 0) = 3: MyData(3, 1) = 0
MyData(4, 0) = 4: MyData(4, 1) = 0
MyData(5, 0) = 5: MyData(5, 1) = 60
MyData(6, 0) = 6: MyData(6, 1) = 60
MyData(7, 0) = 7: MyData(7, 1) = 0
MyData(8, 0) = 8: MyData(8, 1) = 60
MyData(9, 0) = 9: MyData(9, 1) = 60
MyData(10, 0) = 10: MyData(10, 1) = 0
MyData(11, 0) = 11: MyData(11, 1) = 0
MyData(12, 0) = 12: MyData(12, 1) = 60
'波形图外观设置

MSChart1.ChartData = MyData '数据
End With
我想再添加一条蓝色的谁能给下代码！急！！
代码如下所示。用！开头的注释是我加入的主要解释。实现所需效果。
Dim MyData(12, 2) As Double '！加入1维就是增加一条线
'-----x轴坐标值-----Y轴坐标值----------
MyData(0, 0) = 0: MyData(0, 1) = 180 '本句代表了：第一点数据的X轴坐标为0，Y轴坐标为180
MyData(1, 0) = 1: MyData(1, 1) = 960
MyData(2, 0) = 2: MyData(2, 1) = 60
MyData(3, 0) = 3: MyData(3, 1) = 0
MyData(4, 0) = 4: MyData(4, 1) = 0
MyData(5, 0) = 5: MyData(5, 1) = 60
MyData(6, 0) = 6: MyData(6, 1) = 60
MyData(7, 0) = 7: MyData(7, 1) = 0
MyData(8, 0) = 8: MyData(8, 1) = 60
MyData(9, 0) = 9: MyData(9, 1) = 60
MyData(10, 0) = 10: MyData(10, 1) = 0
MyData(11, 0) = 11: MyData(11, 1) = 0
MyData(12, 0) = 12: MyData(12, 1) = 60
'！为新加入的一条线赋值
Dim i As Integer
For i = 0 To 12
MyData(i, 2) = 0.3 * MyData(i, 1)
Next
'波形图外观设置
With MSChart1
.TitleText = "值"
' '设置图线的外观
.Plot.SeriesCollection(1).Pen.Width = 30
.Plot.SeriesCollection(1).Pen.Style = VtPenStyleSolid
'！设置第二条线的外观
.Plot.SeriesCollection(2).Pen.Width = 30
.Plot.SeriesCollection(2).Pen.Style = VtPenStyleSolid
' '设置XY轴

MSChart1.Plot.UniformAxis = False
MSChart1.chartType = VtChChartType2dLine'！必须为线图，二维散点图只有一条线，用来表示散点分布情况
'MSChart1.chartType = VtChChartType2dXY '设置图形为二维散点图MSChart1.ChartData = MyData '数据
End With
效果如下：成功加入了一条蓝色的。
多出来的红线是什么意思呢？
横坐标的R1,R2...这些怎更改呢?
拖一个mschart1到窗体上
代码如下，全部粘贴覆盖。

红蓝两条线。
