MATLAB: Bounding box around image

boximshow

I'm attempting to show an image within a plot, with a bounding box around the image. However, the following results in an image without a bounding box, despite the box being explicitly asked for:
 clear
 close all
 % Create figure
 fig1 = figure;
 % Random plot
 plot( (1:10), randi(10,1,10) )
 % Create new axes within existing
 axes('pos',[.1 .6 .5 .3])
 % Load and show image
 imshow('coins.png')
 a1 = gca;
 % Try turning box on and redrawing
 a1.Box = 'on';
 drawnow;
Any suggestions as to how this might be resolved? I'm hoping there's a simpler way than having to manually draw a box over the top…

Best Answer

Try this:
% Random plot
plot( (1:10), randi(10,1,10), 'LineWidth', 2)
grid on; % Optional
% Create new axes on top of the existing plot.
axes('Position',[.1 .6 .5 .3])
% Load and show image
imshow('coins.png')
axis('on', 'image');  % This is the KEY LINE OF CODE!
