Please help extract variables from mat files and plot

Please help,

I have two .mat files (sit1.1 & site1.2 attached) containing different variables., rhoxy, rhoyx, zxy, zyx, freq, etc.

I want to load this two files and plot, for example extract values for rhoxy vs freq from each file and plot in a single plot.

Thanks!

load('site1.2.mat');
site2 = site;

figure;
plot(site1.freq, site1.zxy, 'DisplayName', 'Site 1'); hold on;
plot(site2.freq, site2.zxy, 'DisplayName', 'Site 2');
xlabel('Freq');
ylabel('zxy');
legend show;

I would add one small improvement. By specifying what variable(s) to load, you minimize the risk of loading a bunch of unneeded variables that could overwrite existing variables.

site1Struc = load('site1.1.mat', 'site');
site1 = site1Struc.site;
site2Struc = load('site1.2.mat', 'site');
site2 = site2Struc.site;
