I have a Perspective Time Series Chart with five series’ on it (2 plots with some limit lines). I am trying to get “Realtime” functionality like the Easy Chart. To achieve this I have set a 60 second polling rate on the data binding for each series array element - which are tied to Named queries.
This sometimes does the trick for a bit, but eventually pens stop polling, and eventually the whole chart goes stale.
In the below example you can see a gap at the end of the top plot, and the whole chart was > 30 minutes old (time when screencap was taken was 12:25).
Any idea why the query polling just stops working?
- The named queries return the “last N hours” of records
- N number of hours comes from the value of a numeric entry field on the View
