When using the Graph Builder, I like to use the smoother when plotting a Y variable against date as the X variable with multiple Y's for each X value. How do I get the smoother to work when I change the Summary Statistic from Mean to N? Currently, when I change to N, the smoother for Mean stays on the chart and I want the smoother for N instead.

The smoother in the Graph Builder platform is based upon all of the data that is being included within the graph, not just the calculated points such as the mean. As illustrated below, here are 2 Graph Builders, where one has all of the raw data that the smoother is calculated on, and the second is calculated on just the mean values. The Lambda values are the same for both graphs. The first graph appears to be based upon the mean, because with the larger number of data points, the smoother is a better estimator.

So if you want the smoother to be based upon the N, you will need to calculate the N for each of your groupings before you enter into Graph Builder, and then ask for the smoother for those data.

I see the option of cubic splines is available in JMP at graph builder when you test the moderating effect of a categorical variable on the effect of a categorical variable to the outcome which happens to be... you guessed it...also categorical variable. Does this make sense? Is that possible?
