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
akZoom(___, handles, ___)
akZoom(___, mButtons_ZoomPanReset, ___)
akZoom(___, zoom_direction, ___)
Note: all input arguments are optional and can be given in arbitrary

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', 'mlr', 'mrl', 'rlm' or '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

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.

%% Simple Plot

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

%% Subplots (mixture of linked and independent zomming for the axes)
ax = NaN(4,1);
for k = 1:4
y = rand(1,15);
ax(k) = subplot(2, 2, k);

%% Different figures (linked)
ax1 = gca;
ax2 = gca;

%% Zoom only along the x-axis

updated file

* constraining the zoom to only the x- or y-axis now supported
* in xy-zoom mode the user can constrain the zoom to one axis by drawing an ROI rectangle that spreads over more than 95% of the plot height or width
* the wrappers are simplified

fix a bug that occurs when fast scrolling with mouse wheel (thanks to Anne-Sophie Girard-Guichon)

included missing file: plotyy_fixZoom.m

* solved problems with axes nested in GUIs (thanks to Benoit Botton)
* solved problems with out-of bounds logarithmic-plots
* improved error handling in wrapper functions
* bugfix for fast scrolling (could previously result in error messages )

*supports now loglog & semilog
*mouse buttons customizable
*unsensitive to data markers & legends
*checks for valid axis limits (log!)
*automatically callable for 2D plots

updated Description

-zooming: replaced patch by rectangle -> faster, visually not dependent on renderer, bug fixed that prevented scroll wheel events after zoom
-mapping of mouse buttons can be customized
-easy usage with 'all' and 'all_linked' (works now with plotyy)

*out-of-the-box functionality with subplots and (multiple) plotyy-axes
*arbitraty linking between different axes can be easily set up
