What type of chart (XY/scatter; Line; column) ?
Can you give us some of the data you used?

I'm attempting to add a trendline to a series of data points in Excell
2007.
But the trendline button is not highlighted and therefore not useful. Is
there a problem with the spreadsheet or has anybody encountered this and
knows of a fix?
