plotutils bug

[John Moses]

I may have found a bug in in plotutils, in graph.  I'm using version 2.4
on an intel linux box, redhat 6.2, helixgnome, kernel 2.2.17.  Using
graph with the grid option 2 produces grid lines through the origin.  My
understanding is that this is the behavior one should get with grid
option 4.  Options 2 and 4 produce identical results.  Here's my input
line:

graph -T ps -F Times-Roman  -h .25 -w .4 -X "DISPLACEMENT (\*mm)" -x -14
14 -y -.1 1.1 -Y "RELATIVE H\sp-\ep COUNT"   -S 4 -m 0 scannc -g 2 -m 1
