Splitting time series into segments

I'm looking to create a plot which is divided into segments.

I have a matrix that looks like 'State_ID' 'Time' 'DD' 'SR' 'H'. State_ID runs from 1-26. I'm looking to create a plot which has a DD, SR, and H values across time on the x axis but divided into different colours or line types according to what the State_ID is?

Use findgroups to segregate the state groups and plot() over those group indices.

Converting the array to a table makes things neater and simpler as can then use varfun/rowfun and friends may be helpful
