Analytics Designer - EmptyChart messages in console causing performance issues

Hi,

in my Analytics Application I got a lot of (~150) these messages in console since I switched to "Refresh Active Widgets Only". Before that I had all my Charts set with "Always Pause" and had turned them on manually with setRefreshPaused(false). This was a lot faster, but much more code was needed.

Any idea from where they come from? I am having a lot of performance issues because of that. My Application takes 10-15seconds for these messages before starting the OnInitialization Script.
