Handle empty data vizualisation

[DovAlduin]

Is your feature request related to a problem? Please describe.
I have no data on a time series in line chart but a linear interpolation is applied by default so I can't see at first glance whether I have data recorded or not.

Describe the solution you'd like
Have a way (checkbox, list) to choose how no data in time series are processed : no visualisation, linear interpolation or any other suggestion

Describe alternatives you've considered

Additional context
The line chart I got with Superset :

And that is what I would like to achieve :

@DovAlduin have you tried using the new "Time-series Chart" visualization which is backed by Apache ECharts. I believe each visualization type handles rendering of missing data differently.

Is it possible to get linear interpolation somehow. I can't esem to find it. In the case of OP he wants to get rid of it, but I'm trying to find a way to get it

This is my desired outcome

Is there anyway doing this?
