how to add 2nd y-axis on give graph?

Dear community, I have written a basic code to plot the results of my findings, but I am struggling to add a second y-axis to the plot. Could anyone please help me with this small issue? Thank you! 😊 The second axis should display the values of L. Here, z represents the coordinates of each ply, starting from 0 at the center and extending symmetrically in both directions.

sigma_x = X(1, :);
sigma_y = X(2, :);
tau_12 =  X(3, :);
L1 = [zeros(1, l),90*ones(1,m)];
L = [L1,fliplr(L1)];
z =nonzeros(z)';
% Plot sigma_x versus z
plot(sigma_x, z, 'DisplayName', '\sigma_x','LineStyle','-','LineWidth',2);
hold on;

% Plot sigma_y versus z
plot(sigma_y, z, 'DisplayName', '\sigma_y','LineStyle','-','LineWidth',2);

% Plot tau_12 versus z
plot(tau_12, z, 'DisplayName', '\tau_{12}','LineStyle','-','LineWidth',2);

xlabel('Stress (MPa)');
ylabel('z (m)');
%xlim([-5e8 5e8]);

% Add legend
legend('Location', 'best','FontSize',12);

% Set limits for y-axis
ylim([min(z) max(z)]);
title("[0_{m}/90_{n}]_{s}")

on this graph I want value of L on right hand side.

Do you mean something like this - yyaxis ?

If not, then please specify the desired output.

[dharmin]

yes yyaxis, where value on Right hand side y-axis is taken from variable L which is storing the orientation data of each ply.

See the documentation for yyaxis. It should be all you need.
