Re: Mingw Octave 3.4.2 - blank gnuplot printouts

[Nit Nit]

Here is the output:

graphics_toolkit('gnuplot')
plot(fft(eye(37)))
print(gcf,'test.png','-dpng','-debug');

Ghostscript command: 'C:\Octave\Octave3.4.2_gcc4.5.2\gs\gs9.02\bin/gswin32c.exe -dQUIET -dNOPAUSE -dBATCH-dSAFER -sDEVICE=png16m -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r150x150 -dEPSCrop -sOutputFile=test.png C:\Users\owner\AppData\Local\Temp\oct-3.eps'

gnuplot-pipeline: 'C:\Octave\Octave3.4.2_gcc4.5.2\gs\gs9.02\bin/gswin32c.exe -dQUIET -dNOPAUSE -dBATCH -dSAFER -sDEVICE=png16m -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r150x150 -dEPSCrop -sOutputFile=test.png C:\Users\owner\AppData\Local\Temp\oct-3.eps & del C:\Users\owner\AppData\Local\Temp\oct-3.eps'

I have dbstop in __gnuplot_print__ and catched the oct-3.eps file and it seems to me that it doesn't contain the actual plot information !

You can add "-debug" to the print command. That will display some detail as to what is being done.
