Hi,
1. I didn't understand -- why does it matter to you if the browser retains
some information about the previous charts? Does this have any visible
symptom?
2. There are better ways to remove all elements from a div than setting
innerHTML to ''. You might have better results if you use one of those.
Regards,
VizBoy.
