I have a data set with stress and strain for 4 different samples as shown above in an excel document titled Dataset #2.1.

Using matlab plot 2 plots - each plot will contain 2 curves, 1 for each sample tested in that group. I wasn't able to upload the full data set so please just show the code that would be used, no need to show real graphs.
