How to adjust the position of a title in a subplot

So I have the following subplot:

With the following code:

figure
subplot(1,2,1)
imagesc(im);
axis equal;
axis off;
hold on;
plot(position(:,1),position(:,2),'o','MarkerEdgeColor','r','LineWidth',1.5,'MarkerSize',10);
title('Detected Particles', 'FontSize',14); 

histpos = [0.5703,0.2707,0.3347,0.4897];
subplot('position',histpos)
hist(FWHM, 6)
colormap default
xlabel('FWHM', 'FontSize',16) 
ylabel('Frequency', 'FontSize',16) 
set(gca,'FontSize',14);
title('Histogram of FWHM Values', 'FontSize',16); 

As you can see, the title for the first subplot is in an odd position and I can't figure out why. It doesn't do that when I have it as a regular figure and not a subplot.

Any suggestions for how to fix it?

Thanks

It's the axis equal that does it -- take out the axis off afterwards and you'll see the position of the title isn't all that funny after all.

The side-by-side subplot is squished horizontally; when you make axis equal that shrinks the image in the y direction but doesn't change the overall axis size.

To fix, make the following changes--

...
xlm=xlim;                                                                   % retrieve x axis limits
title('Detected Particles','Position',[mean(xlm) xlm(1)],'FontSize',14);    % use for title positioning

The axis equal leaves y axis scaled to make the same range as x-axis in center so postioning the title at center and start of x axis moves it to the top edge of the scale image. It's the left edge instead of right since images have origin at upper left instead of LL as a regular plot.

Works perfectly. Thank you!
