spurious horizontal lines in svg output (impulses plot)

Show all headers | View raw

Hello,

we get rendering problems with svg output of the file below. See the problem description, the input files and the svg file here:

http://en.smath.info/forum/yaf_postsm12035_Image-Region.aspx#post12035

The following part from the svg file is meant to create the vertical lines (impulses). Possibly, due to a gnuplot bug there is a small horizontal line in the end (h0.01). If that line is removed from the file, then the plots are correct in whatever viewer. Is there a way to avoid this spurious line?
