no he defined a fixed size which i was trying to avoid also he messed up the fonts so far he hasn't responded to my talk page inquiry in the mean time i have uploaded a new version with a blue graph and a slightly increased font size and changed to font 'verdana' as per preference of fred the oyster it seems that mediawiki always opts for a px width when no fixed size is available take another look and let me know whether you want the size to be fixed
