[scilab-Users] Plotting to file wihtout graphical window

[Calmon Martin]

Hi,

Figures can be used in buffer mode... It's ruled by the pixmap property: i.e.for a figure f, the figure is only in memory if f.pixmap="on". In this way, batch can be run in the background without interfering with other work.

And if you need to check what is on the figure: show_pixmap().

Bests,

I remember I found a way to plot using python from within scilab
somewhere on the web but I can't find it again.
It could be a workaround and I think matplotlib can plot directly to file...
