No, the code you provided has a few issues in adding legends.

Here's the corrected version of the code:

x = categorical({'Present', 'all'});
y = [2363; 2090];
z = [0.19154; 0.17777];
nil = [0; 0];

yyaxis left
bar(x, [y nil], 'grouped')
ylabel('Static Temperature')

yyaxis right
bar(x, [nil z], 'grouped')
ylabel('Mass CO2')

grid on
grid minor

TestL = {'Static Temperature', 'Mass CO2'};
hB = bar(x, [y z], 'grouped');
hLg = legend(hB, TestL, 'Location', 'northwest'); % Use hB instead of X and Y

• With these changes, the legend should appear correctly on your plot. The TestL variable contains the legend labels, and the hLg variable stores the handle to the legend object, which can be used to further customize the legend if needed.

Thank you so much, however, how can I chnage the color of the legend itself to be simialr to the color of the y-axis ?

figure
plot(magic(5))
h = legend("Line "+(1:5));

Here's how you can alter the (background, text, edge) color of a legend:

h.Color = [0.5 0 0.5];
h.TextColor = [1 0.5 0];
h.EdgeColor = 'c';
