I have tried the same page on Firefox Ver 44, Chrome 48 and after update on Chrome 49. They all display the same. No Charts and the increasing "None Events".
I have checked the events list and there are no "None Events" listed. The number of "None Events" far exceeds my total number of events.
I have checked the events table and the level zero events are recent ones from the last few days and is called "Maximum Alarm Level Changed", I assume this is when I was changing alarm levels for testing. Again the level zero events in the table only number at 8158, far less than the 100K plus I saw on the data point details page.
When I look at the event handlers page, under system events there is a line with out a flag called "Maximum Alarm Level Changed". I have now set that to "Do Not Log" in the system settings page.
I opened the developers console on Chrome as you suggested and this is what was shown on the console when the data points details page was opened:

I am not a programmer so am not sure what any of this means.
Do I need to update java?
Thanks for your help.
