I wrote some code that represents this figure:
The code is this:
%% errori relativi
% tau1
figure(2)
sgtitle('ERRORI RELATIVI ')
subplot(1,3,1)
pcolor(a1/l1, y/l1, delta_tau1./abs(tau1)*100);
contourf(a1/l1, y/l1, delta_tau1./abs(tau1)*100)
title('$\Delta \tau_{\%} \ [\%]$');
colorbar('southoutside')
xlabel('$\frac{x}{l}$')
ylabel('$\frac{y}{l}$')
axis equal
xlim([min(min(a1/l1)), max(max(a1/l1))]);
ylim([min(min(y/l1)), max(max(y/l1))]);
grid on
% Q1
subplot(1,3,2)
pcolor(a1/l1, y/l1, delta_Q./abs(Q)*100);
contourf(a1/l1, y/l1, delta_Q./abs(Q)*100)
title('$\Delta Q_{\%} \ [\%]$');
colorbar('southoutside')
xlabel('$\frac{x}{l}$')
ylabel('$\frac{y}{l}$')
axis equal
xlim([min(min(a1/l1)), max(max(a1/l1))]);
ylim([min(min(y/l1)), max(max(y/l1))]);
grid on
% Ek1
subplot(1,3,3)
pcolor(a1/l1, y/l1, delta_Ek./abs(Ek)*100);
contourf(a1/l1, y/l1, delta_Ek./abs(Ek)*100)
title('$\Delta E_{k\%} \ [\%]$');
colorbar('southoutside')
xlabel('$\frac{x}{l}$')
ylabel('$\frac{y}{l}$')
axis equal
xlim([min(min(a1/l1)), max(max(a1/l1))]);
ylim([min(min(y/l1)), max(max(y/l1))]);
grid on
I want to overlay the three graphs and make evident the common area under the 10% error (dark blue area). How can I do this?
