Could you be a little more specific? Was the trendline generated with
Excel's trendline option or did you create it in another area of the
worksheet and then plot it as another series? What type of chart, etc. -
more info will help.
Thanks for answering my question. I have solved the problem.
It was a x/y-graph with dates in the y-axis. There were some false dates in
the colum date' through wich the trendline disappaered outside the screen.
