How can I introduce the break in the plot?

I am using ThingSpeak platform to acquire the data from a temperature sensor. During night time, I do not acquire the data and starting the acquisition on the next day in the morning. When I plot data of last, say 200 acquisitions which includes yesterday's as well as today's data, using Matlab, l see a continuity between the last acquired data and the first data of today. Ideally, there should be break between the last acquired data and the first data of today. How can I introduce the break in the plot? The plot is attached as a reference.

Introduce NaN when you want a line to break.

figure; plot([1 2 3 NaN 5 6 7],'-o');
