Extracting data from a Matlab graph for further plotting in the same graph.

Hello matlab community,

I have a plot of climate data where 5 temperature lines (y) are plotted against time(x). I need to draw a shaded area between the min and max of each X for Y i.e for each year (X) there are 5 temperature values(Y) because there are 5 temperature lines. I need to find the min and max of these 5 temperature values. Like this there are 34 years, so the min and max of such values will be used to draw a shaded area. Any help in doing these will be deeply appreciated.

Thank you in anticipation

If you created the graph, just use the data that you used to create the graph. Why are you trying to extract the data from the graph?

If the question is about plotting shaded areas, attach a brief example of what you're working with.
