Routine Descriptions

PROCEDURE:   eva_ctime,time,y,z
INPUT:
    time: Named variable in which to return the selected time (seconds
          since 1970)
    y:    Named variable in which to return the y value
    z:    Named variable in which to return the z value
KEYWORDS:
    PROMPT:  Optional prompt string
    NPOINTS: Max number of points to return
    PSYM:    If set to a psym number, the cooresponding psym is plotted at
             selected points
    SILENT:  Do not print data point information
    PANEL:   Set to a named variable to return an array of tplot panel numbers
             coresponding to the variables points were chosen from.
    XNORM:   Set to a named variable to return an array of normalized x
             coordinates of each button-click.
    YNORM:   Set to a named variable to return an array of normalized y
             coordinates of each button-click.
    APPEND:  If set, points are appended to the input arrays,
             instead of overwriting the old values.
    VNAME:   Set to a named variable to return an array of tplot variable names,
             cooresponding to the variables points were chosen from.
    COLOR:   An alternative color for the crosshairs.  0<=color<=!d.n_colors-1
    SLEEP:   Sleep time (seconds) between polling the cursor for events.
             Defaults to 0.1 seconds.  Increasing SLEEP will slow eva_ctime down,
             but will prevent eva_ctime from monopolizing cpu time.
    INDS:    Return the indices into the data arrays for the points nearest the
             recorded times to this named variable.
    VINDS:   Return the second dimension of the v or y array.
             Thus  TIME(i) is  data.x(INDS(i))           and
                   Y(i)    is  data.y(INDS(i),VINDS(i))  and
                   V(i)    is  data.v(VINDS(i)) or data.v(INDS(i),VINDS(i))
             for get_data,VNAME(i),data=data,INDS=INDS,VINDS=VINDS
    EXACT:   Get the time,y, and (if applicable) z values from the data
             arrays.  If on a multi-line plot, get the value from the line
             closest to the cursor along y.
    NOSHOW:  Do not show the plot window.
    DEBUG:   Avoids default error handling.  Useful for debugging.
    DAYS, HOURS, MINUTES, SECONDS: Sets time granularity.  For example
             with MINUTES=1, eva_ctime will find nearest minute to cursor
             position.
PURPOSE:
   Interactively uses the cursor to select a time (or times)
NOTES:       If you use the keyword EXACT, eva_ctime may run noticeablly slower.
         Reduce the number of time you cross panels, especially with
         tplots of large data sets.
