I have a chart with a lot of y values. How do I copy just the y values from a series to an array?

I can get the y and x values with this, but it's not what I need, can't seem to figure out how to get to the y values.

VB

 For i = 0 To Chart_Manual_Instantaneous.Series(0).Points.Count - 1
     Debug.Print(Chart_Manual_Instantaneous.Series(0).Points(i).ToString)
Next

Something along the lines of

VB

Dim yArray(Chart_Manual_Instantaneous.Series(0).Points.Count) As Double

For i = 0 To Chart_Manual_Instantaneous.Series(0).Points.Count - 1
   yArray(i)=Chart_Manual_Instantaneous.Series(0).Points(i).Y

Next

might do the trick.
I haven't compiled this so there might be some syntax errors in it.

Thank you, I've tried something very simular and keep getting stuck

VB

Dim yArray(Chart_Manual_Instantaneous.Series(0).Points.Count) As Double

      For i = 0 To Chart_Manual_Instantaneous.Series(0).Points.Count - 1
          yArray(i) = Chart_Manual_Instantaneous.Series(0).Points(i).YValues

      Next

I keep getting "Value of 1-dimensional array of double cannot be converted to double", the "

VB

Chart_Manual_Instantaneous.Series(0).Points(i).YValues

is what's throwing the error.

I got it in a round about way, the xvalue works fine with the code above, there is not a yvalue, it's yvalueS, I suspect there is a bug in there code. But anyways this works

VB

Dim yArray(Chart_Manual_Instantaneous.Series(0).Points.Count) As Double
Dim temp() As Double
For i = 0 To Chart_Manual_Instantaneous.Series(0).Points.Count - 1
    temp = Chart_Manual_Instantaneous.Series(0).Points(i).YValues
    yArray(i) = temp(0)
Next
