Series showing incorrectly on scatter chart
 

I am plotting scatter charts in Excel 2003. I have a diagonal line on each
chart (to show the line x=y), which I put there by adding a "dummy" series -
(0,0), (1,1), (2,2) etc. to give a straight line. However, on some of my
charts this shows up as not one but two straight lines - one showing the
correct x=y line and another one which also goes through zero but has a
different slope. I can't work out why this happens or how to fix it. If I
format the data series to show data markers, all of them lie on the correct
line and none on the incorrect line. I have made sure I haven't inadvertantly
added an extra series to my chart - the incorrect and correct diagonal lines
are definitely part of the same data series. This problem happens on only a
couple of my charts (the ones with the lowest values), even though I have
several other charts linked to the same "dummy" series.
I hope this makes sense. Has anyone got any ideas on how to fix this?

I wonder is you have a tendline added to the non-dummy values. Can you
delete the incorrect line?
Would be happy to look at chart if you send file to my private email

Hi Bernard,
Thanks for that suggestion but it doesn't seem to be a trendline. If I
delete it, it also deletes the correct line. I have emailed you my
spreadsheet - it would be great if you could take a look.
Thanks,
Amy
