Colour coding bar of graphs

how do you create a loop where each time a different bar on a graph is coloured differently

RE: colour coding bar of graphs

To be more specific the loop needs to look through a list of items and then on each sheet colour code the same bar on a graph throughout the worksheet.

RE: colour coding bar of graphs

Hi Rhian

Hope you are well. Here's a way to colour a column chart according to the type of item (in this case fruit).

Say the data looks like this -

Fruit Quantity sold
Pears 200
Oranges 120
Apples 70
Bananas 230
Blueberries 30

Here's the vba code. See if you can adapt it for your example. It assumes the chart already exists and called Chart1.

Dim PointNo As Integer
Dim NumItems As Integer
Dim Items(20) As String ' an array variable of 20 items

Dim n As Integer
n = 1

' count number of items

NumItems = Range("A1").CurrentRegion.Rows.Count - 1

'Add list of items to an array variable
For n = 1 To NumItems
Items(n) = Range("a2").Cells(n, 1).Value
Next n

ActiveSheet.ChartObjects("Chart 1").Activate
ActiveChart.FullSeriesCollection(1).Select

'select the colours one by one
For PointNo = 1 To NumItems

ActiveChart.FullSeriesCollection(1).Point(PointNo).Select
Select Case Items(PointNo)
Case Is = "Apples"
Selection.Format.Fill.ForeColor.RGB = RGB(255, 0, 0)
Case Is = "Pears"
Selection.Format.Fill.ForeColor.RGB = RGB(0, 255, 0)
Case Is = "Oranges"
Selection.Format.Fill.ForeColor.RGB = RGB(255,192, 0)
Case Is = "Bananas"
Selection.Format.Fill.ForeColor.RGB = RGB(255, 255, 0)
Case is = "Blueberries"
Selection.Format.Fill.ForeColor.RGB = RGB(0, 0, 255)
Case Else
Selection.Format.Fill.ForeColor.RGB = RGB(255, 255, 255)

End Select

Next PointNo

Range("A1").Select
End Sub

Let me know how you get on!

Excel tip:

New to Excel 2010 - Sparklines!

Excel 2010 includes a new feature called Sparklines which are tiny charts that fit into a single cell and plot data in cells from the worksheet. There are a host of formatting and styles that can be applied to them and they are really quite interesting.

>insert
>sparklines
>Choose any style you want

You will be asked for the range and it will automatically select the cell your in to insert the sparklines.
