% TIMEAXIS Sets Axes-TickLabels in Time/Date-Format
%
% The Ticks and Labels will set depending on the actual Limit of the Axis.
% The AxisLimits will interpreted in units days !!!
%
%
% TIMEAXIS( AxeHandle , XY , Number , BaseDate )
%
% AxeHandle Handle of Axes, which TickLabels are to set
% default: gca
%
% XY 'x' | 'y' | 'z', specifies Axis
% default: 'x'
%
% Number Requested Number of Intervalls between Labels
% [ LabelNumber TickNumber ]
% default: [8], the TickNumber will set automaticly
% maximum LabelNumber: 50
%
% BaseDate BaseDate of Axis: [ YY MM DD ]
% [ YY MM DD hh mm ss ]
% default: [ 0000 01 00 00 00 00 ]
% 00-Jan-0000 00:00:00, i.e. this Date has day == 0
%
%
% [Msg,LabelAxe,LabelText] = TIMEAXIS( ... )
%
% Msg ErrorMessage from Zoom-Functionality, empty if everything Ok
%
% LabelAxe AxesHandle for a NEW created Axes, which contains the Labels.
% Take care, that the function "gca" can returns this Handle instead
% of the former "AxeHandle".
% Tag: TIMEAXIS
%
% LabelText TextHandles for NEW created AxesLabels,
% which contain the strings for Year or Date
% Tag: TIMEAXIS_LABEL
%
% Sometimes the LabelTicks and Minorticks looks unequal spaced, that occured on
% Intervalls in units days, example: 1 5 10 15 20 25 1 5 10 ...
% 1 10 20 1 10 ...
% In this case the Day 30 gets no tick !
%
% TIMEAXIS( ... , 'zoom' ) activates a ZoomFunction, the TickLabels will
% updated automaticly after each Zoom, requested m-file: AXE_ZOOM
%
% Click and Drag with Left MouseKey to zoom in
% Click with right MouseKey to zoom back
%
% DoubleClick with left MouseKey zooms to origin
%
% TIMEAXIS( AxeHandles , ... , 'xzoom' ) activates a ZoomFunction
% for multiple axes along the X-Axes, the TickLabels will
% updated automaticly after each Zoom, requested m-file: XZOOM
%
% Click and Drag with Left MouseKey to zoom in
% Click with right MouseKey to zoom back
%
% DoubleClick with left MouseKey zooms to origin
