this fails as many browsers will not display svg
and it fails as you hardcoded the ranges, its supposed to work automatically
after all ...
heres my suggestion

set size ratio 1./1.6 ; set term svg ; set output '|convert - test.gif' ; set key bottom ; set ylabel "stdout lines" ; set y2label "stderr lines" ; set xlabel "SVN revision" ; set ytics autofreq tc rgbcolor 'red' ; set y2tics autofreq tc rgbcolor 'green' ; set grid xtics ytics y2tics lc rgbcolor '#E0E0E0' ; plot 'stdlc-2.95.3.csv' using 1:2 with points pt 7 ps 0.2 axis x1y1 title 'stdout', 'stdlc-2.95.3.csv' using 1:3 with points pt 7 ps 0.2 axis x1y2 title 'stderr'


and s/;/\n/g ;)
