Hi,

I have a graph in grafana which shows me the filling of a salt container.  
It works great but watch my screenshot. There was a time where there are no values available and the line do not connect to the next available value. What do I have to do to make sure, that the graph always connects to the next value also if the value appears a few days later than the last one? (normaly two values a day but sometimes longer interval).  
The only thing I have activated since now is "Null value: connected"

Thanks a lot

Isn't the data just running out of the scale ?
