If so, that has to be considered quite surprising.  Nor is the 
difference of behaviour really tied to using Linux vs. Win32, but rather 
to which PNG driver you're using.

Your script absuses 'replot',  which causes it to generate not one, but 
*four* pages of output.  A PNG can't really hold more than one.

These lines:

> plot filename using ($1):(((int($2)%147)/147.2*2*pi/5)-pi/5) axes x1y1 
> title 'TARGET_M1' with lines
> replot filename using ($1):(((int($3)%147)/147.2*2*pi/5)-pi/5) axes x1y1 
> title 'ACTUAL_M1' with lines
> replot filename using ($1):(((int($4)%147)/147.2*pi/5)) axes x1y1 title 
> 'ERROR_M1' with lines
> replot filename using ($1):14 axes x1y2 title 'CURRENT_M1' with lines

should be replaced with something like:

   plot \
     filename using ($1):(((int($2)%147)/147.2*2*pi/5)-pi/5) \
       axes x1y1 title 'TARGET_M1' with lines, \
     '' u 1:(((int($3)%147)/147.2*2*pi/5)-pi/5) \
       axes x1y1 title 'ACTUAL_M1' with lines, \
     '' u 1:(((int($4)%147)/147.2*pi/5)) \
       axes x1y1 title 'ERROR_M1' with lines, \
     '' u 1:14 axes x1y2 title 'CURRENT_M1' with lines

... and what happened?
