Package: gnuplot
Version: 4.0.0-2.1
Severity: minor

When drawing a vector plot, arrows that leave the viewport will have
their arrowheads reversed. See attached sample plot; the same data is
plotted twice, but in the first situation, the arrow is entirely in the
yrange, in the second case it is not - and suddenly the arrowhead
appears on the wrong end.
