There is a flaw in the gauge chart in which, if you don't specify a fixed size container, repeated redraws will shrink the height and width by 4px each time. The problem involves the cellpadding on the table which is 2px. We can remove it, but I'd like to move the padding to another place where it won't have this effect.
