quick question about add constant line



Dear Ferreters,
 
Does anyone know how to add straight lines to the line plots?
 
I have a series, the axis defination is as below: 
 
  define axis/t=-7:7:1 tax
  define grid/t=tax tgrd
  file/var=corr/grid=tgrd/col=15 d:\data.asc
 
Now, I need add zero line to the plot. I just can plot zero line for the range[0,7], and failed for the range [-7,0]. Can anyone give me some hints?
 
Thanks.
