How to include Filling or shadow the un-observed times to the observed time of a phenomena?

Hello everyone,

I have observed some phenomena on differernt days of year and at differrent time. To plot this observations against time and days of year, I have used the plot command

plot([194 194],[3 5],'r','linewidth',3);  %  194 is the day of  year and 3 and 5 shows the start and end time of observation in hours.

We got the figure below

The phenomena is not observed at time in hours from [1 2] and [7 9] on the same day.

How can show the un-observed times of the phenomena along the line of observed time?

Any help will be appreciated.

THANKS

You are showing from day 193 to 195. I presume 194 means midnight plus one second on day 194. You can see that nothing is plotted at day 194+1/24 through 194+2/24, and from 194+7/24 through 194+9/24. So how do you want to indicate that there is an observation, or no observation, on your plot? The correct time window is showing - we just need to know how observations or no observations are to be indicated.

Sir, i want to plot the unobserved time [1 2 ] and [7 9] in hour on the same line of the observation time.

onservation time means at which the phenomena (PMSE) is observed.

unobserved time means the time at which the radar ran but the phenomena is not observed. I want to get the plot as below.

Thanks

In my first figure, it is shown that PMSE phenomena is observed at time interval of [3 5] in hours on day number 194.
