Re: gnuplot changes affects octave

[Dmitri A. Sergatskov]

With data file that looks like that:

address@hidden octave]$ cat a.dat
1 2
2 4
nan nan
3 6
4 8

With gnuplot 4.0
plot "a.dat" w line
plot "a.dat" using 1:2 w line
plot "a.dat" using ($1):($2) w line

all produce the same plot -- line with a break between x=2 and x=3

In gnuplot 4.1 it changed:

plot "a.day" w line
     gives an error message:
gnuplot> plot "a.dat" w line
             ^
        Bad data on line 3

plot "a.dat" using 1:2 w line
      plots a line w/o a break

plot "a.dat" using ($1):($2) w line
     plots a line w/ a break (the same as gnuplot 4.0)

So I would think the easiest change would be to get octave
issue "pl 'file' using ($1):($2) w line" ...

Sincerely,

Dmitri.
