Hi All,

I can add lots of different trend lines to my Excel charts... except one...
I need to reflect seasonal fluctuations, so that whilst during the summer
months work levels tend to fall, the overall trend of the business is
increasing & I'd like to see a trend line showing the future expected growth,
but which still shows a drop-off during the summer.

Is this possible with a trend line, or do I need to use a function to create
the trend figures & then chart them?

Thanks in advance for your help

Regards
Colin Foster
