Graph Builder: plotting geometrical mean with 95% confidence intervalI'm using JMP 16.2. I need to plot the geometric mean (with error bars indicating 95%CI) of a biological outcome for two groups of patients over four time-points. When selecting line I can choose Geometric Mean as Summary Statistic, but when I select Confidence Interval as Error Interval nothing happens. I presume this is because this would be Confidence Interval for means, not geometric means. Any idea how to get the desired result? Any help would be greatly appreciated.
Data Exploration and VisualizationRe: Graph Builder: plotting geometrical mean with 95% confidence intervalHello @arnaudsteyaert ,
To use the confidence interval for the geometric mean for graphing, you need to first create a column in your data table with the formula. You can see the details of the calculation on the following page.

Once you have created the column, you can create a graph by following these steps.
--Select Graph --> Graph Builder
--Select Y and drag it to the left of the Y axis.
--Select Time and drag it to the bottom of the X axis.
--Select Group and drag it to the Overlay Zone
--Select Columns with Lower and Upper Confidence Interval Formula and drag them to the Interval zone.
--Select "Geometric Mean" in the "Summary Statistics" section.
Please see the attached sample data for your information. I hope it helps.
