Options null value=connected not works

Hi everyone !

I have an issue with the panel graph. I want to the graph relies each point with a line, but it doesn’t do that when I zoom to mush.

On the image, there are point before and after the time windows but it doesn’t display the line between.

Some one know how to do that please ?

Can you show the before screenshot when you have data ? What type of data you have there ?
