Can I improve the efficiency of space use while saving my figures?

2 views (last 30 days)
Hello everyone. I am currently using matlab to generate some figures. I am using the following code:
figure
subplot(3,1,1)
contourf(Y,X, stdRVTotal3D)
hold on
axesm mercator;
plot(coastlon,coastlat,'k', 'LineWidth', 1.5)
axis([-20 -10 23 32])
c2 = colorbar;
caxis([0, 2.8]);
xlabel('Longitude(^o)')
ylabel('Latitude(^o)')
title('4 RV')
subplot(3,1,2)
contourf(Y,X, stdRV3RV3D)
hold on
axesm mercator;
plot(coastlon,coastlat,'k', 'LineWidth', 1.5)
axis([-20 -10 23 32])
c2 = colorbar;
caxis([0, 2.8]);
xlabel('Longitude(^o)')
ylabel('Latitude(^o)')
title('3 RV')
subplot(3,1,3)
contourf(Y,X, stdRV2RV3D)
hold on
axesm mercator;
plot(coastlon,coastlat,'k', 'LineWidth', 1.5)
axis([-20 -10 23 32])
c2 = colorbar;
caxis([0, 2.8]);
xlabel('Longitude(^o)')
ylabel('Latitude(^o)')
title('2 RV')
sgtitle('STD wind velocity in the Y direction (m/s) nodes')
However, the resulting figure has a lot of empty space.
Can someone please give me some advice on how to get bigger subplots inside of the same figure?
Best regards.
Jaime.

You can try increasing the height of the figure, e.g., by dragging the edge of it, or by setting its Position in your code.
f1 = figure('Color','g');
make_subplots();
f2 = figure('Color','g','Position',[0 0 577 900]);
make_subplots();
f2 = figure('Color','g','Position',[0 0 577 1800]);
make_subplots();
function make_subplots()
subplot(3,1,1)
axesm mercator;
subplot(3,1,2)
axesm mercator;
subplot(3,1,3)
axesm mercator;
sgtitle('STD wind velocity in the Y direction (m/s) nodes')
end
