MATLAB: Plotting streaming data at unequal intervals

MATLABplot

I am trying to plot a data that is streamed. It is saved in my logger only when particular value is changed.
For example: 
loggedData = [1 NaN NaN 2 NaN NaN NaN 10 NaN NaN NaN]; 
actualData = [1 1 1 2 2 2 2 10 10 10 10]; 
time = [0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 10]; 
plot(time, loggedData) 
plot(time, actualData)
I would like to plot(time, loggedData) but it would not work similar to plot(time, actualData). Changing from loggedData to actualData would increase the storage unnecessarily but only option I know as of now.
If I do a scatter plot, it would not connect with lines inbetween as I wanted.
Is there any solution?

See fillmissing(): https://www.mathworks.com/help/releases/R2020a/matlab/ref/fillmissing.html 
loggedData = [1 NaN NaN 2 NaN NaN NaN 10 NaN NaN NaN];
time = [0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 10]; 
plot(time, fillmissing(loggedData, 'previous'))
