[Scilab-users] An error occurred during export: Unable to create export file, not enough memory. Decreasing the number of elements or the size of the figure should fix this error

[Federico Miyara]

Heinz,

The first thing I would consider is if really it is relavant to plot 155 
000 data points, taking into account that neither the screen nor any 
printing system can present such a resolution.

If you have 155 000 points they aremost likelycontaminated with noise. 
You could approximate them with a lsq_splin using few break points, 
probably around 20, and then use this spline to obtain about 1000 points 
or less.

If you need, instead, to show in your plot the noise you can do this: 
divide the domain of the function in a number of bins of a width more or 
less equivalent to the pixel or printed dot (there will be in general no 
more than about 1000 bins), then find the min and max within each bin 
and retain them, then plot again.

Finally, you can export using svg and as was suggested some time ago 
(sorry I don't recall by whom), open it in Inkscape, a free open source 
software (there is also a portable version, so no need to install it). 
Then export it as wmf (Windows metafile). Then you can paste in word 
processors and you retain the full quality, the fonts are fonts, not 
just a bundle of random pixels. It tried this and works very well.

You can also edit the image within the word processor, if a final touch 
up is convenient (change font tyope or size, line color, etc.).

Regards,

Federico Miyara
