A formula trace does not get immediately added to the databrowser and also does not immediately updated #2703

Closed rjwills28 closed 2 years ago

rjwills28 commented 2 years ago

We came across an issue when users were adding formula traces to the data browser that they did not appear immediately in the plot. Equally if a user updates the formula, the changes do not get immediately displayed. The fomula only gets re-evaluated when the samples change, i.e. if the live PV variable changes or the received archived data changes.

I have created a fix for this issue which identifies when the formula has been updated and registers this change causing the formula to be re-evaluated.
