I have a process that runs through thousands of records over several hours.

There is a web page that uses AJAX calls to update a table and some charts 
with the details of the progress, refreshing every 15 seconds.  If I have 
the charts commented out, while the page is waiting for the timer to kick 
off another refresh, the CPU utilized by that instance of IE is almost 
nothing.  However, when the code to populate the charts is enabled, the CPU 
goes to 18%, then within a few minutes it's at 50% and stays there.

This is a sample of one of the charts.  There are two pie charts and a bar 
chart.  The only thing I changed is that the data is hard coded, but is 
sampled from the actual page.

Do I need to delete the DOM object and recreate it before each refresh or 
something?  This has been really confused and looking to change charting 
tools, but generally I like everything about Google.

Thanks for any help.
