Confidence intervals on estimated marginal means profileplot

Postby liame7 » Sat Apr 05, 2014 3:07 pm

Hello,

I have run a mixed repeated measures anova, comparing the effects of a drug to placebo, on symptom severity, over three study days. I would like to present the estimated marginal means profile plot, as it shows the drug and placebo lines diverging very nicely on the symptom measure. However, I cannot add confidence intervals to the markers. The "Show error bars" button on chart editor is greyed out.
This is with the latest version of SPSS.

Any help would be greatly appreciated.

Thanks
