Hi

When I plot colorbar, it reduces the size of my actual plot. I have 5 subplot and each has a separate colorbar. How to fix this issue?

I want to plot colorbar for each subplot and next to subplot. how can i solve it?

how can I adjust the ticks on colorbar (interval between colorbar ticks)?

One option would be to stretch the figure by adjusting the 'Position' property. It is possible to re-position it and stretch (or compress) it vertically as well, depending on what you want as the result. See the documentation on the Position property for a full description and details.

Example —

x = 0:999;

y = (1:5:25).'+sin((1:5:25).'*2*pi*x/20);

figure

for k = 1:5

subplot(1,5,k)

plot(x, y(k,:))

xlim([0 20])

colorbar

end

sgtitle('Original')

figure

for k = 1:5

subplot(1,5,k)

plot(x, y(k,:))

xlim([0 20])

colorbar

end

pos = get(gcf, 'Position');

set(gcf,'Position',pos+[-50 0 250 0]) % Shift Slightly Left & Stretch To Right

sgtitle('Stretched Width')

@Star Strider Here is my code to obtain Prob_vp0, Prob_vs0, Prob_rho0.....and are plotted against VD as:

x2 = [1500:50:6000]';

Prob_vp0 = zeros(length(VD), length(x2));

x3 = [800:50:3800]';

Prob_vs0 = zeros(length(VD), length(x3));

x4 = [2000:10:2800]';

Prob_rho0 = zeros(length(VD), length(x4));

x5 = [20:1:64]';

Prob_qp0 = zeros(length(VD), length(x5));

x6 = [10:1:40]';

Prob_qs0 = zeros(length(VD), length(x6));

for i=1:length(VD)

Prob_vp0(i,:) = ksdensity(vp0(i,:),x2);

Prob_vp0(i,:) = Prob_vp0(i,:)/sum(Prob_vp0(i,:));

Prob_vs0(i,:) = ksdensity(vs0(i,:),x3);

Prob_vs0(i,:) = Prob_vs0(i,:)/sum(Prob_vs0(i,:));

Prob_rho0(i,:) = ksdensity(rho0(i,:),x4);

Prob_rho0(i,:) = Prob_rho0(i,:)/sum(Prob_rho0(i,:));

Prob_qp0(i,:) = ksdensity(qp0(i,:),x5);

Prob_qp0(i,:) = Prob_qp0(i,:)/sum(Prob_qp0(i,:));

Prob_qs0(i,:) = ksdensity(qs0(i,:),x6);

Prob_qs0(i,:) = Prob_qs0(i,:)/sum(Prob_qs0(i,:));

end

The Online Run feature has some (necessary) constraints, so you will likely get slightly different results than appear here when you plot it. Make appropriate adjustments to get the result you want.

The only change I made to your original posted code was to remove the ‘set(gcf,'position',...)’ calls for each figure, since they are not necessary here.
