Try

set datafile missing "?"

in there somewhere.  It creates more of stacked histogram for me. 
(Can't really explain why it looks the way it does or how ? is 
interpreted without that modification.)

Also, I don't think it is the case, but how is 1986/87 interpreted?  Is 
1986 a column on its own and then 87 another column?
