Try the Matlab onramp course. It will teach you all the basics you need to get yourself started.

Once you've done that, the documentation will be your best friend for all things Matlab. If you want to learn how to plot two variables against each other, google "matlab plot" and the top result is the manual on how to use the function, the inputs it can take and multiple examples.

Agreed. Ch 9 of MATLAB Onramp introduces plotting in MATLAB.

Btw, you have not shared your data with us. Your mat file is actually a function for importing a mat file.

>> load('tidegauge.mat')
Error using load
Unable to read MAT-file C:\Users\clapierr\OneDrive - MathWorks\MATLAB Answers\tidegauge.mat. Not a binary MAT-file. Try load -ASCII to read
as text.
 
>> load('tidegauge.mat','-ascii')
Error using load
Unable to read file 'tidegauge.mat'. Input must be a MAT-file or an ASCII file containing numeric data with same number of columns in each
row.
 
>> type('tidegauge.mat')
function importfile(fileToRead1)
%IMPORTFILE(FILETOREAD1)
%  Imports data from the specified file
%  FILETOREAD1:  file to read
%  Auto-generated by MATLAB on 14-Jan-2021 09:39:26
% Import the file
newData1 = load('-mat', fileToRead1);
% Create new variables in the base workspace from those fields.
vars = fieldnames(newData1);
for i = 1:length(vars)
    assignin('base', vars{i}, newData1.(vars{i}));
end
