I have two sets like
SINRo=[3.16455696202532 4.74683544303798 6.32911392405063 7.91139240506329 9.49367088607595 11.0759493670886 12.6582278481013 14.2405063291139 15.8227848101266 17.4050632911392 18.9873417721519 20.5696202531646 22.1518987341772 23.7341772151899 25.3164556962025 26.8987341772152 28.4810126582278 30.0632911392405 31.6455696202532]

Add a "hold on" statment which basically will make the two plots combined. I have modified your code below:

Look at the axes function (https://www.mathworks.com/help/matlab/ref/axes.html) I put together a quick example below with your data. You could also try normalizing your data or resampling it to make it line up. All depends on what your analysis requires.
