How to Interrupt a serie?

How can I interrupt serie at certain point, then continue from later point? For example I have date time axis as Y, then the data exist until certain date, then there is no data and later again I have data. What I want is NOT interpolate last data point where data has been interrupted with continuation, but I want to stop the plot and continue once data still there.

In the screenshot above the linear slope is due to missing data. What I want is to avoid that line. Still I want all that interrupted data to be within the same serie.

Data is being sampled each 5 minutes. If the gap is more that, then it is considered as interruption.

Basically I need to know how to break the DateTimeAxis.
