Nice find. I've run into some inexplicable garbage collection issues where canvas elements in an early version of flot ended up never getting released. I could figure out no way to clear these, but I remember the flot code made heavy use of closures. I should go revisit the code and see if this might explain it. I ended up simply hanging on to the elements and reusing them, had to patch flot to achieve this.
