Hi,

I am trying to zoom one part in the subplot figure. For example, I want to zoom one part of the subplot(2,2,1). I use the axes 'axes('position',[0.3 0.2 0.4 0.4])' function, but it will create a zoom part for the whole figure, rather than zooming the defined subplot. Does anyone know how to zoom the defined area in subplot?

Thanks,

Best regards,

Di

在 MATLAB Online 中打开

axes('position', ...) does not zoom into the axes. It sets the position of the axes relative to the figure.

To zoom into a section of the axes you need to change the xlim and ylim properties. Also set the data aspect ratio (daspect) if you want to maintain the aspect ratio of the data when zooming.

x = rand(1,200);

y = rand(1,200);

figure()

subplot(2,1,1)

hold on

scatter(x,y)

rectangle('Position',[.6 .2 .2 .4],'EdgeColor','r', 'LineWidth',2)

daspect([1,1,1])

title('full data')

subplot(2,1,2)

hold on

scatter(x,y)

xlim([.6 .8])

ylim([.2 .6])

rectangle('Position',[.6 .2 .2 .4],'EdgeColor','r', 'LineWidth',2)

daspect([1,1,1])

title('zoomed')

Hi Adam，

Thank you for your help. But can I plot the zoomed part into the subplot figure？Do you know how to do this？

Thanks，

I don't understand what you're asking, "...into the subplot figure". My answer has 2 subplots just for demonstration purposes. The 2nd subplot contains the solution.

The two links at the bottom of my answer might be what you're looking for.
