Changing colour of a chart series based on conditions using vba - excel

Question

I am trying to code using vba so that a series on a chart is formatted based on certain criteria. My coding is as follows
Sub CreateChart()
Dim NPOINTS As Integer
Dim NVAL(1000) As Range, XVAL(1000) As Range, YVAL(1000) As Range
Dim Score(1000) As Range
Sheets("Scenario").Select
Range("B4").Select
NPOINTS = Worksheets("Scenario").Range(Selection, Selection.End(xlDown)).Rows.Count
Set Scenario = Worksheets("Scenario")
ActiveSheet.Shapes.AddChart2(240, xlXYScatter).Select
NVAL0 = "B3"
XVAL0 = "C3"
YVAL0 = "D3"
SCORE0 = "E3"
For i = 1 To NPOINTS
Set Score(i) = Cells(Range(SCORE0).Offset(i, 0).Row, Range(SCORE0).Column)
Set NVAL(i) = Cells(Range(NVAL0).Offset(i, 0).Row, Range(NVAL0).Column)
Set XVAL(i) = Cells(Range(XVAL0).Offset(i, 0).Row, Range(XVAL0).Column)
Set YVAL(i) = Cells(Range(YVAL0).Offset(i, 0).Row, Range(YVAL0).Column)
Scorei = Score(i).Value
ActiveChart.SeriesCollection.NewSeries
ActiveChart.FullSeriesCollection(i).Name = NVAL(i)
ActiveChart.FullSeriesCollection(i).XValues = XVAL(i)
ActiveChart.FullSeriesCollection(i).Values = YVAL(i)
If Scorei <= 10 >= 0 Then
ActiveChart.SeriesCollection(i).Points.Interior.Colour = _
RGB(0, 255, 0) 'Green
ElseIf Scorei <= 30 >= 11 Then
ActiveChart.SeriesCollection(i).Points.Interior.Colour = _
RGB(0, 255, 0) 'Green
ElseIf Scorei <= 60 >= 31 Then
ActiveChart.SeriesCollection(i).Points.Interior.Colour = _
RGB(0, 255, 0) 'Green
ElseIf Scorei <= 100 >= 61 Then
ActiveChart.SeriesCollection(i).Points.Interior.Colour = _
RGB(0, 255, 0) 'Green
Else
MsgBox "ERROR :- Score out of range"
End If
Next
With ActiveChart
'chart name
.HasTitle = False
'X axis name
.Axes(xlCategory, xlPrimary).HasTitle = True
.Axes(xlCategory, xlPrimary).AxisTitle.Characters.Text = "INFLUENCE"
'y-axis name
.Axes(xlValue, xlPrimary).HasTitle = True
.Axes(xlValue, xlPrimary).AxisTitle.Characters.Text = "IMPORTANCE"
.SetElement (msoElementLegendRight)
.Location Where:=xlLocationAsNewSheet, Name:="Priority Chart"
End With
End Sub
Unfortunately when I run it, it fails with "Object doesn't support this property or method and then when I press Debug it highlights the following line
ActiveChart.SeriesCollection(i).Points.Interior.Colour = _
RGB(0, 255, 0) 'Green
Where am I going wrong?
I appreciate any help.

Answer 1

just
ActiveChart.SeriesCollection(i).format.Fill.ForeColor.RGB =RGB(0, 255, 0)

Answer 2

The .Points() is a collection.
You will need to cycle through all its elements and change the color one by one.
The left most point is .Points(1), the right most point is .Points.count
as per: Change the Point Color in chart excel VBA
Also there is no such thing as interior colour for points.
There are 4 relevant options as per: https://msdn.microsoft.com/en-us/vba/excel-vba/articles/point-object-excel
MarkerBackgroundColor
MarkerBackgroundColorIndex
MarkerForegroundColor
MarkerForegroundColorIndex
As per comment from Jon Peltier it is not recommended to make use of the colorindex as this is a legacy from excel <2003
