Peter,

Yes, I can. It turns out that removing the charts and starting from scratch
did do the trick, but I introduced another error when I was retyping the
code, so I thought I hadn't resolved it.

The solution appears to be that it looks like the chart was corrupt.
Thanks for all your help!

As an update, I've removed all charts from the workbook, and inserted a
new
one with the same setup as before. Unfortunately, despite this, the code
still falls over on the second value when trying to update that series.

Peter,

Thanks for your reply. I've had a go (changing my XValues back to
Values
which I had originally used) and adding the X-axis, but I'm still
getting the
same error. Based on the fact that you didn't have any problems, I'm
starting to wonder if the chart is corrupt. I'll recreate it as a new
chart
and see what happens...
