Proposal
when the data is not grouped , we could use line with markers.
every markers correspond to the available data. if there is no marker, this would mean that the line is "just" a point to point connection.
when the data is grouped by. the cluster interval is known, therefore the line can be shown only when there is available data on that cluster.
Hi Oana
Thank you for raising this Idea and our apologies for not responding in a timely manner.
We had quite a few internal discussions about your idea and came to the conclusion that an implementation allowing to hide the line between two points when data is not available at the grouped frequency is unfortunately not feasible at the moment.
Instead, we would recommend you to build your own widget, which gives you full control. There are plenty of examples available on GitHub showing how this can be achieved. To make that even easier, with Cumulocity IoT 10.16, onwards you can utilize the new extension concept that allows you to build an extension package that can then be easily added to any Cumulocity IoT Application. You can find more details on this here.
