please help me plot

[David Forel]

Hello - I just installed Cygwin on an XP Home laptop.  Below are the two Octave commands I entered and the result.



octave:1> x = 1:1:5;
octave:2> plot(x);
octave:3>
gnuplot> set terminal aqua 1 enhanced
                      ^
         line 0: unknown or ambiguous terminal type; type just 'set terminal' for a list


gnuplot> plot "-" using ($1):($2) axes x1y1 title "" with lines linestyle 1 ;
              ^
         line 0: use 'set term' to set terminal type first


gnuplot> 1 1
         ^
         line 0: invalid command


gnuplot> 2 2
         ^
         line 0: invalid command
