Adding error bars on individual data point

Hi,

I'm trying to add error bars on each of my data points with different value that I already calculated manually before, so I just need to enter those values to get the error bars in my curve. However, I've tried and checked all of the options at the "Modify Trace Appearance" menu and I still can not figure this out. Can somebody give me some suggestions about this?

Thank you

Have you seen the 'error bars' checkbox in the 'Modify Trace Appearance' dialogue? The options for that allow you to choose a constant value, % of base, or square root of base or +/- a wave. Since you mention you have calculated the values manually, I would suggest you save the error bar values as a wave and use the +/- wave option.
