Hi,

On the Y Error Bars tab of the format dialog is the option to define
custom +/- values. These can be linked directly to the computed values
you already have.

See Jon Peltier's explanation.

certainly computer standard errors for my data, but how does one connect the
two? That is how can one display computed standard error bars above and below
data points?
