Shading specific regions in a plot

Hi, I have a plot as attached in the picture. I would like to shade a specific portion of the plot and add labels to it. For eg: I have to shade the regions from time 30 to 50 minutes only for the green-line(Good workshop). I tried using 'ShadedtimeSeries' function, but it makes the shading for all the values of all the individual lines in the plot. Any help to solve this will be appreciated.

Try the patch() or fill() function.
