## TPLOT_WINDOW

[List of Routines]

    NAME:
     tplot_window
    PURPOSE:
     Allowd various widget-like features in a tplot window, this is
     accomplished by setting up the window as a draw widget.
    CALLING SEQUENCE:
     tplot_window, tplot_vars
    DESCRIPTION:
     Called just like tplot, e.g.,

       tplot_window, tplot_variable_names

     (The variable names are optional, if left out, then the previous set
     of tplotted variables are used)

     Once tplot_window is called, the all succeeding "tplot" commands are
     sent to that first window, unless tplot is called using the WINDOW
     keyword. (To get a new widget, call tplot_window again.)

     Tplot_window makes the tplot window a draw widget, and enables
     keyboard commands, e.g.,
          'z' for zoom in by 50%;
          'o' for zoom out by200%;
          'r' for reset to initial time range;
          't' for interactive tlimit, which allows you to set
              the plotted time range by clicking same as in a regular
              window;
          'b' for shift back by 25%;
          'f' for shift forward by 25%;
          'c' centers the plot on the cursor, without zooming
     Arrow keys work too, up zooms in, down zooms out, left shifts back,
     right shifts forwards.

     All tplot keywords are allowed except window and wshow. The draw widget
     does not respond to click events, so that calling tlimit, ctime, etc..
     from the command line still works.

     Note that the widget has no 'memory' so if you zoom out right after
     zooming in, you don't necessarily return to the same time range, unless
     you are careful about where on the window you start.
     The zoom in commands key on the cursor position on the plot, while the zoom
     out commands zoom out from the center of the current plot.

     Note that all issues with multiple windows have not been sorted
     out. To return control of tplot to a given window, call
     tplot with no arguments except for the appropriate value using the
     window keyword, e.g.,
        tplot, window = 32 will return control to the original
        tplot_window.
    INPUT:
     tplot_vars = tplot variable names or numbers
    OUTPUT:
     no explicit output, just plots and keywords
    KEYWORDS:
     Same as tplot.pro, excluding WINDOW:
       TITLE:    A string to be used for the title. Remembered for future plots.
       ADD_VAR:  Set this variable to add datanames to the previous plot.  If set
             to 1, the new panels will appear at the top (position 1) of the
             plot.  If set to 2, they will be inserted directly after the
             first panel and so on.  Set this to a value greater than the
             existing number of panels in your tplot window to add panels to
                 the bottom of the plot.
       LASTVAR:  Set this variable to plot the previous variables plotted in a
             TPLOT window.
       PICK:     Set this keyword to choose new order of plot panels
                 using the mouse.
       VAR_LABEL:  String [array]; Variable(s) used for putting labels along
         the bottom. This allows quantities such as altitude to be labeled.
       VERSION:  Must be 1,2,3, or 4 (3 is default)  Uses a different labeling
       scheme.  Version 4 is for rocket-type time scales.
       OVERPLOT: Will not erase the previous screen if set.
       NAMES:    The names of the tplot variables that are plotted.
       NOCOLOR:  Set this to produce plot without color.
       TRANGE:   Time range for tplot.
       NEW_TVARS:  Returns the tplot_vars structure for the plot created. Set
             aside the structure so that it may be restored using the
                 OLD_TVARS keyword later. This structure includes information
                 about various TPLOT options and settings and can be used to
                 recreates a plot.
       OLD_TVARS:  Use this to pass an existing tplot_vars structure to
         override the one in the tplot_com common block.
       GET_PLOT_POSITION: Returns an array containing the corners of each
         panel in the plot, to make it easier to overplot and annotate plots
       HELP:     Set this to print the contents of the tplot_vars.options
             (user-defined options) structure.
