(random thoughts) It initially felt strange to me to bind
style
todataStreams
, since styles are metadata and not streamed. I see that it follows the synchro-chart API though, and these are essentiallyDataStreamStyles
. Would we ever want to swap out synchro-charts as a viz library? If not then this approach seems fine.There was a problem hiding this comment.

how we bind
styleSettings
will be component specific, right nowiot-connector
is a bit specific to Synchro Charts, but we can refactor it as necessary as the need arises asiot-connector
is purely an internal helper and not intended to be used as part of the offerings of the library
