% ozeegplot() - Scroll (horizontally and/or vertically) through multichannel data.
%             Allows vertical scrolling through channels and manual marking
%             and unmarking of data stretches or epochs for rejection.
% Usage:
%           >> eegplot(data, 'key1', value1 ...); % use interface buttons, etc.
%      else
%           >> eegplot('noui', data, 'key1', value1 ...); % no user interface;
%                                                         % use for plotting
% Menu items:
%    "Figure > print" - [menu] Print figure in portrait or landscape.
%    "Figure > Edit figure" - [menu] Remove menus and buttons and call up the standard
%                  Matlab figure menu. Select "Tools > Edit" to format the figure
%                  for publication. Command line equivalent: 'noui'
%    "Figure > Accept and Close" - [menu] Same as the bottom-right "Reject" button.
%    "Figure > Cancel and Close" - [menu] Cancel all editing, same as the "Cancel" button.
%    "Display > Marking color" > [Hide|Show] marks" - [menu] Show or hide patches of
%                  background color behind the data. Mark stretches of *continuous*
%                  data (e.g., for rejection) by dragging the mouse horizontally
%                  over the activity. With *epoched* data, click on the selected epochs.
%                  Clicked on a marked region to unmark it. Called from the
%                  command line, marked data stretches or epochs are returned in
%                  the TMPREJ variable in the global workspace *if/when* the "Reject"
%                  button is pressed (see Outputs); called from pop_eegplot() or
%                  eeglab(), the marked data portions are removed from the current
%                  dataset, and the dataset is automatically updated.
%     "Display > Marking color > Choose color" - [menu] Change the background marking
%                  color. The marking color(s) of previously marked trials are preserved.
%                  Called from command line, subsequent functions eegplot2event() or
%                  eegplot2trials() allow processing trials marked with different colors
%                  in the TMPREJ output variable. Command line equivalent: 'wincolor'.
%     "Display > Grid > ..." - [menu] Toggle (on or off) time and/or channel axis grids
%                  in the activity plot. Submenus allow modifications to grid aspects.
%                  Command line equivalents: 'xgrid' / 'ygrid'
%     "Display > Show scale" - [menu] Show (or hide if shown) the scale on the bottom
%                  right corner of the activity window. Command line equivalent: 'scale'
%     "Display > Title" - [menu] Change the title of the figure. Command line equivalent:
%                  'title'
%     "Settings > Time range to display"  - [menu] For continuous EEG data, this item
%                  pops up a query window for entering the number of seconds to display
%                  in the activity window. For epoched data, the query window asks
%                  for the number of epochs to display (this can be fractional).
%                  Command line equivalent: 'winlength'
%     "Settings > Number of channels to display" - [menu] Number of channels to display
%                  in the activity window.  If not all channels are displayed, the
%                  user may scroll through channels using the slider on the left
%                  of the activity plot. Command line equivalent: 'dispchans'
%     "Settings > Channel labels > ..."  - [menu] Use numbers as channel labels or load
%                  a channel location file from disk. If called from the eeglab() menu or
%                  pop_eegplot(), the channel labels of the dataset will be used.
%                  Command line equivalent: 'eloc_file'
%     "Settings > Zoom on/off" - [menu] Toggle Matlab figure zoom on or off for time and
%                  electrode axes. left-click to zoom (x2); right-click to reverse-zoom.
%                  Else, draw a rectange in the activity window to zoom the display into
%                  that region. NOTE: When zoom is on, data cannot be marked for rejection.
%     "Settings > Events" - [menu] Toggle event on or off (assuming events have been
%                  given as input). Press "legend" to pop up a legend window for events.
%
% Display window interface:
%    "Activity plot" - [main window] This axis displays the channel activities.  For
%                  continuous data, the time axis shows time in seconds. For epoched
%                  data, the axis label indicate time within each epoch.
%    "Cancel" - [button] Closes the window and cancels any data rejection marks.
%    "Event types" - [button] pop up a legend window for events.
%    "<<" - [button] Scroll backwards though time or epochs by one window length.
%    "<"  - [button] Scroll backwards though time or epochs by 0.2 window length.
%    "Navigation edit box" - [edit box] Enter a starting time or epoch to jump to.
%    ">"  - [button] Scroll forward though time or epochs by 0.2 window length.
%    ">>" - [button] Scroll forward though time or epochs by one window length.
%    "Chan/Time/Value" - [text] If the mouse is within the activity window, indicates
%                  which channel, time, and activity value the cursor is closest to.
%    "Scale edit box" - [edit box] Scales the displayed amplitude in activity units.
%                  Command line equivalent: 'spacing'
%    "+ / -" - [buttons] Use these buttons to +/- the amplitude scale by 10%.
%    "Reject" - [button] When pressed, save rejection marks and close the figure.
%                  Optional input parameter 'command' is evaluated at that time.
%                  NOTE: This button's label can be redefined from the command line
%                  (see 'butlabel' below). If no processing command is specified
%                  for the 'command' parameter (below), this button does not appear.
% Required command line input:
%    data        - Input data matrix, either continuous 2-D (channels,timepoints) or
%                  epoched 3-D (channels,timepoints,epochs). If the data is preceded
%                  by keyword 'noui', GUI control elements are omitted (useful for
%                  plotting data for presentation). A set of power spectra at
%                  each channel may also be plotted (see 'freqlimits' below).
% Optional command line keywords:
%    'srate'      - Sampling rate in Hz {default|0: 256 Hz}
%    'spacing'    - Display range per channel (default|0: max(whole_data)-min(whole_data))
%    'eloc_file'  - Electrode filename (as in  >> topoplot example) to read
%                    ascii channel labels. Else,
%                   [vector of integers] -> Show specified channel numbers. Else,
%                   [] -> Do not show channel labels {default|0 -> Show [1:nchans]}
%    'limits'     - [start end] Time limits for data epochs in ms (for labeling
%                   purposes only).
%    'freqlimits' - [start end] If plotting epoch spectra instead of data, frequency
%                   limits of the display. (Data should contain spectral values).
%    'winlength'  - [value] Seconds (or epochs) of data to display in window {default: 5}
%    'dispchans'  - [integer] Number of channels to display in the activity window
%                   {default: from data}.  If < total number of channels, a vertical
%                   slider on the left side of the figure allows vertical data scrolling.
%    'title'      - Figure title {default: none}
%    'xgrid'      - ['on'|'off'] Toggle display of the x-axis grid {default: 'off'}
%    'ygrid'      - ['on'|'off'] Toggle display of the y-axis grid {default: 'off'}
%    'ploteventdur' - ['on'|'off'] Toggle display of event duration { default: 'off' }
%    'data2'      - [float array] identical size to the original data and
%                   plotted on top of it.
%
% Additional keywords:
%    'command'    - ['string'] Matlab command to evaluate when the 'REJECT' button is
%                   clicked. The 'REJECT' button is visible only if this parameter is
%                   not empty. As explained in the "Output" section below, the variable
%                   'TMPREJ' contains the rejected windows (see the functions
%                   eegplot2event() and eegplot2trial()).
%    'butlabel'   - Reject button label. {default: 'REJECT'}
%    'winrej'     - [start end R G B e1 e2 e3 ...] Matrix giving data periods to mark
%                    for rejection, each row indicating a different period
%                      [start end] = period limits (in frames from beginning of data);
%                      [R G B] = specifies the marking color;
%                      [e1 e2 e3 ...] = a (1,nchans) logical [0|1] vector giving
%                         channels (1) to mark and (0) not mark for rejection.
%    'color'      - ['on'|'off'|cell array] Plot channels with different colors.
%                   If an RGB cell array {'r' 'b' 'g'}, channels will be plotted
%                   using the cell-array color elements in cyclic order {default:'off'}.
%    'wincolor'   - [color] Color to use to mark data stretches or epochs {default:
%                   [ 0.7 1 0.9] is the default marking color}
%    'events'     - [struct] EEGLAB event structure (EEG.event) to use to show events.
%    'submean'    - ['on'|'off'] Remove channel means in each window {default: 'on'}
%    'position'   - [lowleft_x lowleft_y width height] Position of the figure in pixels.
%    'tag'        - [string] Matlab object tag to identify this eegplot() window (allows
%                    keeping track of several simultaneous eegplot() windows).
%    'children'   - [integer] Figure handle of a *dependent* eegplot() window. Scrolling
%                    horizontally in the master window will produce the same scroll in
%                    the dependent window. Allows comparison of two concurrent datasets,
%                    or of channel and component data from the same dataset.
%    'scale'      - ['on'|'off'] Display the amplitude scale {default: 'on'}.
%    'mocap'      - ['on'|'off'] Display motion capture data in a separate figure.
%                     To run, select an EEG data period in the scolling display using
%                     the mouse. Motion capture (mocap) data should be
%                     under EEG.moredata.mocap.markerPosition in xs, ys and zs fields which are
%                     (number of markers, number of time points) arrays.
%                    {default: 'off'}.
%    'selectcommand' - [cell array] list of 3 commands (strings) to run when the mouse
%                      button is down, when it is moving and when the mouse button is up.
%    'ctrlselectcommand' - [cell array] same as above in conjunction with pressing the
%                      CTRL key.
% Outputs:
%    TMPREJ       -  Matrix (same format as 'winrej' above) placed as a variable in
%                    the global workspace (only) when the REJECT button is clicked.
%                    The command specified in the 'command' keyword argument can use
%                    this variable. (See eegplot2trial() and eegplot2event()).
