error bars for non-programmer

I need to add error bars, but creating a curve (+SE/-SE) for each point on several curves "uses up" too many curves. If this cannot be done another simple way, I am willing to try a command line solution, if you give me precise instructions on how to do it.

Thank you.

You don't need to create a new curve for every point, just a new curve for every curve for which you want error bars. If the positive and negative errors are the same you can get by w/ one new curve; if they're different you need 2 new curves.

The n'th amplitude from the curve used as the error source is used as the error value for the n'th point in the curve for which you want error bars.

I hope this clears it up a bit; if not please let me know.
