The same width problem happens for me with Ubuntu 13.10 "saucy" on LXPanel 0.6.1 -- The graphs are unreadable and with fixed width no matter how I change "System monitor width" within indicator-multiload preferences. Changing the width there seems to only change the "virtual size" of the applet, but the actually displayed size is fixed, like a mask.
