I have a large set with several variables, some records have missing data for some of the variables. I am trying to generate a histogram (by group) but I get an extra histogram for the missing data (missing data in the group variable). Here is a small example code of what I have. I want to know if there is any way to ignore the missing data in the Group.
Thanks,
