Hi,

Apologies if my question appears basic or I don't include relevant info!

I've been asked to plot a sigmoid curve to plot the sales cycle of a
product. I don't know if a sigmoid curve is alway a certain shape (like the
product life cycle ) or if it depends on the data I enter? Either way, how
would I go about plotting one in Excel 2003?

I then need to plot several points along this curve - is this also doable?

Thanks in advance,
Claire
