Hi everyone,
I would like to make one Colorbar for a 2x2 subplot on right hand side. I have read the answer of a similar question: https://uk.mathworks.com/matlabcentral/answers/144453-how-to-make-one-colorbar-for-all-subplots
But I couldn't see the tick of the colorbar as well as the title. Could you please help?
Thanks
Here is my code:
subplot(2,2,1)
[C,h]=contour(f_mat,sig_mat,real(L_lossy_mat).'*1e9,'LineWidth',2);
h.LevelList = [-1 -0.5 -0.2 -0.05 0.0 0.03 0.04 0.05 0.06];
clabel(C,h,'LabelSpacing',100,'FontSize',14,'FontWeight','bold','FontSmoothing','on','Interpreter','Latex')
ylabel('$\sigma^{(\textbf{I})}$ (S/m)','Interpreter','Latex')
xlabel('$f$ (MHz)','Interpreter','Latex')
title('$R=\infty$','Interpreter','Latex','Color',[125/255 30/255 125/255])
ax=gca;
ax.YDir = 'reverse';
ax.YScale = 'log';
ax.YMinorGrid = 'off';
ax.TickLabelInterpreter = 'latex';
xticks([37 46 55])
yticks([0.01 0.1 1 10])
yticklabels({'0.01','0.1','1','10'})
subplot(2,2,2)

The problem is with the location and size of the colorbar. By changing the Position of the colobar to the left i.e., reduce the left value of the position: [left bottom width height] you can see the complete colorbar but on the top of subplots 2 & 4.
For this particular problem I would suggest you to make a subplot grid of 2x3 instead of 2x2 so that you can make use of the space of 3 & 6 subplots and change the Position property of the colorbar accordingly. The following code will help you
