How can I produce Matlab Figure with lower memory size?

Hello all, I produced a 3 GB data file which gives me plots for some variables of interest. When I save the generated plot, it takes 200 MB, I need it to be saved in much lower size. Does anyone have a solution? I am an amateur matlab user by the way. Thanks.

How are you currently doing the saving of the plot?

when I save it in png format it is okay, around 1 MB. but when saved in .fig format, it takes 206 MB. I need to share it in editable format for other colleagues.

If your colleagues are all using R2014b or later, then use savefig() with the 'compact' option.

I made a little test

>> plot( randn(1,100) )
>> savefig(gcf,'c:\tmp\savefig')
>> print( 'c:\tmp\dsvg', '-dsvg' )
>> print( 'c:\tmp\dpsc2', '-dpsc2' )
>> print( 'c:\tmp\dpng', '-dpng' )

with a simple line plot. The savefig, -dps2 and -dsvg files were all approx. 50% larger than the -dpng file.

"editable format for other colleagues" they are all "editable" with appropriate tools. To edit with Matlab chose savefig. Any(?) browser may be used to view the svg file.
