You cannot plot a mat file. You can run the following command to first load the data stored in the mat file to the workspace, and then plot the variables you want to.

load 'S01E.mat'

IF you follow your way of coding with `load`, the below code will work.

x = load('S01E.mat');
figure;plot(x.data);

or, `x.data` seems a cell of structure data,

x = load('S01E.mat');
D = cell2mat(cellfun(@(element)element.(SOME_FIELD), x.data)');
figure;plot(D);

Good luck!

For your next question on MATLAB Answers, you should paste your code in text, not in image as it's difficult for others to reproduce your code from image.
