Could you fix the template in the master sheet? Or does simply changing the
data cause the chart to change?

An alternative might be to run a macro. This will change charts in the
active workbook:

Sub FixCharts()
Dim sh As Object
Dim cht As Chart
Dim chobj As ChartObject

For Each cht In ActiveWorkbook.Charts
cht.PlotBy = xlColumns ''' or xlRows ''' ***
Next
For Each sh In ActiveWorkbook.Sheets
For Each chobj In sh.ChartObjects
chobj.Chart.PlotBy = xlColumns ''' or xlRows ''' ***
Next
Next

End Sub

In the two places highlighted by *** you need to make sure the appropriate
alignment is being specified. See this post if you aren't sure how to use
this code:

O.k. today I am at my cleints place and I have looked a bit more into it.
I
have checked last years databases and graphs appear to be o.k. for the
first
half of the year (until July / August) while those covering the rest of
the
year are skewed. They upgraded to Excel 2007 in June/July. This means,
that
old, existing graphs were not changed, but what has changed is that when
the
MASTER Sheet (= a template for entering data, which then automatically
creates a time vs value graph) is copied for recording data from a new
product batch, the x - and y - axis switch. Therefore, all graphs after
July
/ August are skewed. This problem persists to this day, meaning that every
new worksheet that is created contains skewed graphs, making the problem
(=workload) bigger.

I can correct the problem manually in the following way:
1. right click on the graph
2. Click 'Select data'
3. Click 'Switch Row / Column'
4. Click 'Switch Row / Column' again
5. Correct the format of the x-axis to its original format

However, there are many graphs, and if I am unable to solve the problem,
we
will have to ommit using graphs.

If you are able to provide me with an email address, I can send you one of
the files, and you can have a look whether the same thing happens on your
computer, and if so, work out what the problem is.

Jon, sorry for my long silence.

What you are describing is exactely what happens, i.e. that the values
on
the x-axis (horizontal) become the values on the y-axis (vertical).
This
obviously messes up the the graph.

Unfortunately I can't quite remember what manual changes I make to get
the
graph back to the way it used to be (because this problem occurs not on
my
computer but on my clients computer where I go only once a month or
so). I
think I am changing the graph back by going into the 'Source Data'
Menue,
and
then change the 'Series in' from Rows to Coloumns, or vice versa. I
will
be
going to my client again on Monday, and after I have made the change, I
will
get back to you to tell you exactely what I do.

I'm having trouble understanding "the x - axis becomes the y-axis".
How
does
the chart change its appearance? What steps do you take to "change it
back"?

Are the values that were plotted on the horizontal axis now plotted on
the
vertical axis, and the values that were plotted on the vertical axis
now
plotted on the horizontal axis? Do the axis titles switch positions?
Does
a
(vertical) column chart become a (horizontal) bar chart?

Jon
I use very simple line (mostly) and bar charts. The time line
(usually
dates, covering between a few weeks to one year) is shown on the x -
axis
and
the values, e.g. temperatures in a composting pile, are shown on the
y -
axis. The problem I am having is that the x - axis becomes the
y-axis
and
vice versa, messingup the chart and making it useless. This happened
automatically when Excel 2007 was installed, and it still happens
when
a
template (= worksheet established in Excel 2007) is copied within an
Excel
document to create a new worksheet for a new product batch.

I can manually switch the x- and y - axis back so that the graph
look
o.k.
again, but this is a frustrating way of doing it, and there must be
a
way
of
preventing this from happening.

Does this explain it better?

the
actual
data switch in the series formulas?

I am managing a database of lab results for an external company.
That
compnay
recently upgraded from Excel 2003 to Excel 2007, which resulted
in
the
automatic swap of the x - and y - axis in all time - value graphs
that
are
inbeded in each worksheet of the database. I have labouriously
reversed
many
of the automatic changes, but still have a long way to go.
However,
the
most
frustrating thing is that as soon as staff copy template
worksheets,
in
which
the x - and y - axis have been corrected so that time is whown on
the
x -
axis and values on th y - axis, to enter data for a new product
batch,
the
x
- and y - axis revert back the wrong way round. Trying to deal
with
this
problem caused by Excel 2007 has been one of the most frustrating
work
experiences I have had for a very long time. Any ideas of what
might
help?
The other thing is that I can't try your suggestions striaght
away,
as,
luckily, I don't have Excel 2007; I can only try things, when I
am
working
on
my client's system.
