We have many ajax calls in out app to get XML from the app server to load in some of our charts. Problem is sometimes these calls can take a bit. Is there a way to put the chart in a waiting state or have it just post a custom message anytime we want? Using setDataURL is out of the question on these BTW.
I originally had the thought to use the caption text of an empty chart to do this but that darn "no data to display" message comes up instead.
Any thoughts or ideas?
