On my machine, an image of 2048x2048xfloat (16 MB) displays in 2 seconds on Linux-X11-gnuplot and 3 seconds with wine-wgnuplot.exe. Drawn from Octave-Linux-X11 via imagesc(), it takes 7 seconds. I wonder why as the script obtained via drawnow() takes also 2 seconds to display. I cannot test Octave-Windows. --- PM ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
