st: RE: graph matrix

["Jun Xu" <mystata@hotmail.com>]

Thanks a lot.  I played around with it for a while (including getting rid of 
those missings) and found that I have to transform x2 from int to float, the 
problem solved.  However note that x3 also has int format.  Just don't know 
why this is happening.  Could anyone else give me more input on this?  
Really appreciate


One of the missing values in x2 might contain the invalid character for
a numeric variable -'-. I would check the obs reported missing.
