In analyze->Distribution is it possible to create a CDF plot for the data being looked at. However, is does not seem possible to using a "grouping" feature to create mutiple trendlines on the same CDF graph, similar to what is possible in Analyze->Fix Y by X.

Does anyone know how do to this? Thanks!

Arrange your data so that the values for all groups are in one column (say, Data) with the group name identifying each row in a second column (Say ID). (If you have a bunch of columns in a table, use Tables>Stack to get the data in this form). Then do Fit Y by X with Data-->Y and ID-->X. From the resulting platform output click on the red triangle for Data and select CDF Plot.
