hi

I wrote this code to help me to plot a normal distribuion curve.

Sub Plot()
Dim mu As Single
Dim segma As Single
Dim xFirst As Single
Dim xLast As Single
Dim X As Single
Dim Y As Single
Dim lngRow As Long
Dim StepValue As Single
Dim Steps As String

xFirst = Sheets(1).Range("B1")
xLast = Sheets(1).Range("B2")
Steps = Sheets(1).Range("B3")
mu = Sheets(1).Range("B4")
segma = Sheets(1).Range("B5")

StepValue = (xLast - xFirst) / (Steps - 1)
lngRow = 0
X = xFirst

With Sheets(1).Range("A10")
Do While X <= xLast
.Offset(lngRow, 0) = X
Y = Application.WorksheetFunction.NormDist(X, mu, segma,
False)
.Offset(lngRow, 1) = Y
X = X + StepValue
lngRow = lngRow + 1
Loop
End With

End Sub

As you can see that the procedure generates points in columns A and B to be
used to create the chart. Is it possible to generate the graph without
seeing these points on the sheet. I mean that you have an array.

Plz help!!
