allows direct zooming and panning with the mouse in 2D plots.
Default mouse button functions (can be customized, see below):
Scroll wheel: zoom in/out
Left Mouse Button: select an ROI rectangle to zoom in
Middle Mouse Button: pan view
Right Mouse Button: reset view to default view
SYNTAX:
akZoom
akZoom(___, handles, ___)
akZoom(___, mButtons_ZoomPanReset, ___)
akZoom(___, zoom_direction, ___)
Note: all input arguments are optional and can be given in arbitrary
order.

DESCRIPTION:
akZoom() activates mouse control for all axes-objects in the current
figure with default settings.

akZoom(___, handles, ___)
activates mouse control only for the axes given by the handles
argument which can be:
a) a single axis handle.
b) an array of axis handles. In this case all axes will be linked,
i.e. panning and zooming in one of the axes will affect the others as well.
c) a cell array consisting of axis handles and/or arrays of axis
handles. In this case mouse control is activated for all axes inside
the cell but linking is only activated for axes in a common array.
d) one of the following strings:
i) 'all': activates mouse control for all axes in all open figures.
The axes will not be linked except for axes belonging to the same
plotyy-plot or yyaxis-axes
ii) 'all_linked': activates mouse control for all axes in all open
figures and links all axes.

akZoom(___, mButtons_ZoomPanReset, ___)
will use akZoom with customized mouse buttons.
mButtons_ZoomPanReset can be:
lmr, lrm”、“高”、“推广”,“那么使用rlm”或“rml”
where the letters stand for the left, middle and right mouse buttons
So 'lmr' means: left=ROI-zoom, middle=pan and right=reset.
Note: If you want to use a certain mouse button pattern as default,
just change mButtons_ZoomPanReset_default in the "Settings" section
below.

akZoom(___, zoom_direction, ___)
will use akZoom with zooming only along the specified direction.
zoom_direction can be: 'x', 'y', or 'xy'
Note: If you want to use a certain zoom direction as default, just
change zoom_direction_default in the "Settings" section below.

For further customization check the "Settings" section in the code.

EXAMPLES:
%% Simple Plot
figure
plot(10:24,rand(1,15));
akZoom();

%% Subplots (independent zooming for the axes)
figure
for k = 1:4
y = rand(1,15);
subplot(2, 2, k);
情节(y);
end
akZoom();

%% Subplots (mixture of linked and independent zomming for the axes)
figure
ax = NaN(4,1);
for k = 1:4
y = rand(1,15);
ax(k) = subplot(2, 2, k);
情节(y);
end
akZoom({[ax(1),ax(3)],ax(2),[ax(3),ax(4)]});

%% Different figures (linked)
figure;
imshow(imread('peppers.png'));
ax1 = gca;
figure
imshow(rgb2gray(imread('peppers.png')));
ax2 = gca;
akZoom([ax1,ax2]);

%% Zoom only along the x-axis
figure
plot(log(1:150),rand(1,150));
akZoom('x');
