SVG Synoptic Display Editor

[htoraby]

In the SVG Synoptic Display Editor there are Special Codes like !DCRxxx (returns the point description) , is there a way to get the time of last channel connect or dis-connect like this? Or there is a way to get data from realtimeData collection ?

No, there no direct possibility to obtain any additional info from realtimeData.
This is an important feature that I intend to add eventually. Also management of string, array, date/time, geo and structured object values are a necessity.
Currently the only way is to create an additional tag and update its value using custom scripting, for example by customizing the cs_custom_processor template.

I have added a GraphQL server that can return data from some collections.
Can be accessed by
http://127.0.0.1/apollo

I will expand the data available and study how to retrieve this data from the SVG.

How it can be access from SVG Synoptic Display Editor, you think? If adding new Special Codes so why added GraphQL server?

[riclolsen]

I won't add codes for now. I think it is better indeed to request graphql query directly.
I have put an example in the knh2.svg display.

Yes, I see example, actually it is so complicated task in this level, although it can be usable for some special cases, but I prefer to use Special Codes like !DCRxxx
Anyway, adding the GraphQL is a good feature.
