In what way didn't it work - it worked for me as far as "Next" is
concerned.

To cater for next / previous ensure your previous button is named
"Previous"
(case sensitive) and include the following in my previous example

dim x as long
If Application.Caller = "Previous" Then
x = -1
Else
x = 1
End If

'code

If x = -1 Then
If serHighlit <= 1 Then serHighlit = scol.Count
Else
If serHighlit = scol.Count Then serHighlit = 0
End If
serHighlit = serHighlit + x

'code

If you only want one series on the chart at any one time, forget about all
the re-formatting stuf and change the .Values property (ie Y-Values) of
seriescollection(1). This would be column of your range values say Offset
from the leftmost column by the static variable serHighlit

Thanks Peter for your reply!

I tried your sollution, but unfortunatly it didn't do the job.

What I want is this:

Case:
The user pushes a commandbutton called "next".

Sollution:
The chart shows the next column of data.

The same thing with the "Previous" button, but of course this time the
previous column.

The number of columns in the worksheet varies. It can be from 10 to 250.

Column A is the X- values, Column B - are the logdata that I want the
user
to view through.

Not sure if you want to only want one series at any one time on the
chart,
or merely highlight the next of your series of the 5. This does the
latter.

Sub Test()
Dim sr As Series
Dim scol As SeriesCollection
Static serHighlit As Long

On Error GoTo errH
Application.ScreenUpdating = False

If TypeOf ActiveSheet Is Worksheet Then
'' Worksheet chart
Set scol = ActiveSheet.ChartObjects(1).Chart.SeriesCollection
Else
'' chart-sheet
Set scol = ActiveSheet.SeriesCollection
End If

If serHighlit = scol.Count Then serHighlit = 0

serHighlit = serHighlit + 1

For Each sr In scol
sr.Border.Weight = 1
sr.Border.ColorIndex = xlNone 'xlAutomatic
Next

scol(serHighlit).Border.ColorIndex = xlAutomatic '3
scol(serHighlit).Border.Weight = 4

errH:
Application.ScreenUpdating = True
If Err.Number Then
MsgBox "error"
End If

End Sub


If you want all 5 series visible on the chart, change the pair of
colorindex
values to the commented pair.

I want a chart to update so that I can se either next column or
previous
column in the chart. I want the user to push a commandbutton (next
column
or
previous column) to see data from one column at the time. The first
column
is
the x- values and the rest is the y- values.

FYI: The X- values are the time axis. The rest of the columns are
logdata.
The point is to see how the logdata varies.
