[PATCH] fio_generate_plots with setable resolution

[PATCH] fio_generate_plots with setable resolution

[-- Attachment #1.1: Type: text/plain, Size: 467 bytes --]

Hi!

Use

fio_generate_plots somename 1600 1200

or something like that.

Just quit and dirty ATM. On interest I can make up a patch for inclusion 
in fio package *after* I finished my article ;).

Fonts tend to get small on hi resolutions. It seems gnuplot takes them as 
pixel not points/dots (related to some dots per inch).

Ciao,

Thanks, applied with usage print updated (and 1024x768 default res, the
old 800x600 is pretty small).
