I want to make a line graph that ranges from 0 to 20 and has 200 data points. This whole chart thing is confusing to me. I can make a chart that displays vertical data but I cannot seem to be able to integrate the horizontal data into the chart.
I know this is an inadequate descritption, but I'm having a hard time explaining the problem.
If you can help me based upon the sketchy description I've given, you are a better man than I...
Thanks!
Bill

Thanks for the info, I've been that far already. What I meant was that I know how to display the data as 0-200 (okay, I lied - it actually has 201 data points - sorry!), but what I want to do is have the range be 0-20 with 201 data points in between.
I know I'm not explaining this clearly. Please keep doing what you're doing. By sorting out what I do know from what I don't know, eventually we'll get to the bottom of this. :)

Not sure if this is what you mean?
Option Explicit
Private garray(0 To 200, 1 To 1) As Single
Private Sub Form_Load()
Dim i As Long
Randomize Timer
For i = 0 To 200
garray(i, 1) = Rnd * 10 + 5
Next i
'
With MSChart1
.chartType = VtChChartType2dLine
With .Plot.Axis(VtChAxisIdY).Va
.Auto = False
.Minimum = 0
.Maximum = 20
.MajorDivision = 10
End With
.Plot.Axis(VtChAxisIdX).Ax
.ChartData = garray
End With
Me.WindowState = vbMaximized
End Sub
Private Sub Form_Resize()
MSChart1.Move Me.ScaleLeft, Me.ScaleTop, Me.ScaleWidth, Me.ScaleHeight
End Sub
Maybe you meant this way...
Option Explicit
Dim garray(0 To 200, 1 To 2) As Single
Dim serx As Series
Private Sub Form_Load()
Dim i As Long
Randomize Timer
For i = 0 To 200 ' datapoints
garray(i, 1) = i / 10
garray(i, 2) = Rnd * 0.5 + 0.5
Next i
'
With MSChart1
.chartType = VtChChartType2dXY
.Plot.Axis(VtChAxisIdY).Va
.Plot.Axis(VtChAxisIdY).Va
.Plot.Axis(VtChAxisIdY).Va
.Plot.UniformAxis = False
End With
'
MSChart1 = garray ' populate data grid
Me.WindowState = vbMaximized
End Sub
Private Sub Form_Resize()
MSChart1.Move Me.ScaleLeft, Me.ScaleTop, Me.ScaleWidth, Me.ScaleHeight
End Sub
Just a comment to let you know that I haven't forgotten this thread. I just haven't been able to work on this problem lately. Programming is a minor part of my work and right now I've been overloaded with other stuff. I hate it when someone asks a question and then just drops off the face of the earth.

To change the chart from Vertical bars to Line all you need to do is to set the ChartType property to 2 dimentional lune:
si if your chart is named MsChart1
then add this line of code:
MSChart1.chartType = VtChChartType2dLine
If you need more help , just ask.
