I have seen some examples which uses an Arrow to Indicate Special Points on Excel chart like this. But i want to achieve this using VBA. For example if some point on chart is greater then 90 then it shows an arrow corresponding to that point.
Please suggest on how should I go about it in VBA. Any help would be appreciated.
Update
Apart from just changing the point color is there any other good suggestion to make that point more prominent.
Update 2
Right now i am using this code.
For Each oCell In Range("e4:e" & LastRow) 'loop
If oCell.Value < sd13 Then 'rule 13s
Range("V4").Value = "Rule 13s voilated!"
Range("V4:w4").Interior.Color = RGB(255, 0, 0)
ActiveWorkbook.Sheets("LDL-C").ChartObjects("Chart 1047").Chart.SeriesCollection(1).Points(j).MarkerBackgroundColor = RGB(255, 0, 0)
End If
Next
Not sure how to do it with an arrow but here is a way to just change the colour of the point of interest:
With ActiveSheet.ChartObjects(ChartName).Chart.SeriesCollection("NCDs")
For currentPoint = 1 To .Points.Count
If Range("G" & currentPoint + 34).Value = True Then
With .Points(currentPoint).Format
.Fill.BackColor.RGB = RGB(50, 150, 50)
.Fill.ForeColor.RGB = RGB(50, 150, 50)
.Line.ForeColor.RGB = RGB(50, 150, 50)
End With
Else
With .Points(currentPoint).Format
.Fill.BackColor.RGB = RGB(150, 50, 50)
.Fill.ForeColor.RGB = RGB(150, 50, 50)
.Line.ForeColor.RGB = RGB(150, 50, 50)
End With
End If
Next currentPoint
End With
Just change the names and the condition clause…
Also maybe the .Points(currentPoint) object has x,y location properties which you could use to position your arrow. Not sure about that though but it seems like a good starting point.

Would this help?
With ActiveChart
For i = 1 To .SeriesCollection.Count
a = .SeriesCollection(i).Values
For l = 1 To .SeriesCollection(i).Points.Count
If mymax < a(l) Then
mymax = a(l)
.SeriesCollection(i).DataLabels.Select
Selection.Format.Line.Visible = msoTrue
Selection.Format.Line.Visible = msoFalse
.SeriesCollection(i).Points(l).DataLabel.Select
.SeriesCollection(i).Points(l).Select
.SeriesCollection(i).DataLabels.Select
.SeriesCollection(i).Points(l).DataLabel.Select
With Selection.Format.Line
.Visible = msoTrue
.ForeColor.ObjectThemeColor = msoThemeColorAccent1
.ForeColor.TintAndShade = 0
.ForeColor.Brightness = 0
End With
With Selection.Format.Line
.Visible = msoTrue
.Weight = 2
End With
End If
Next l
Next
End With

Answer：
Yeah, gotta have VBA. Problem with VBA is that someone has to remember to run the procedure, or set up a Worksheet_Calculate event, or whatever, so when the data changes, which it inevitably does, the chart keeps up with the data.
So here’s my non-VBA approach, which relies on Excel formulas.
Simple data, supplied by Siddharth in his answer. I’ve added a column, which I call MAX. The formula in cell C2, copied down to C11, is
=IF(B2=MAX(B$2:B$11),B2,NA())
The first chart plots the regular series of data in a clustered column chart. The second chart has MAX added to it. In the third chart I’ve changed the Overlap to 100%, so the blue bar covers the corresponding gray bar. Next chart I’ve added data labels to the MAX series. In the last chart I’ve formatted the data label to show series name, and the font color =matches the bar color.
So here is the original data and chart (upper) and changed data with changed chart (below). The formulas did it all, no need to somehow rerun the VBA.
What’s cool is if I have a tie for first place, I get two labeled blue bars, with no extra effort.
Not a big stretch to add a third series to indicate the MIN.
Answer：
ActiveChart.FullSeriesCollection(1).Select
With Selection
.MarkerStyle = 8
.MarkerSize = 5
End With
Selection.MarkerStyle = 2
ActiveChart.ChartArea.Select
With Selection.Format.Line
