You don't need to make separate series. If each point you plot is an average
of a set of numbers and you also have the corresponding standard deviation
values in a parallel range, you can add the standard deviation values as
custom error bars. I show how to do this in Excel 2003 here:

It's somewhat more tortuous to accomplish this in 2007, because of the
unexpected changes they've made to the user interface. I don't have 2007
handy right now, but I think you add error bars from the middle chart tools
contextual tab, then you have to delete the X error bars, and customize the
values of the Y error bars.

It sounds like you need to do this:
Select the series you want to show the deviation for
Go to the Chart tools > Layout Ribbon
Choose "Error Bars" drop-down list (in the Analysis group near the right
hand end)
choose the type of bars you need, or go for more options

Cheers Adam, Ive managed to work it out. I am stucj or something else
if you could help. I need to make the them seperate series, so that I
can enter different standard deviations on the chart. How do i lay out
my results so that I can get different series.
