I would use the max function with two output arguments, then use the index value to find the x-value:
[ymax,idx] = max(y);
xmax = x(idx);

You could use datacursortmode the axes 'ButtonDownFcn' or max() on the line's 'YData'. This is what I would do.
plot(rand(1,10));
hLine = findobj(gca,'type','line');
[~,idx] = max(hLine.YData)
hLine.XData(idx)
