procedure stats[, brange][, erange], [/full], [/chan], [ret=variable], [/quiet] |
Procedure to display some simple statistics.
Statistics are done on the contents of buffer 0. One can specify the range over which statistics will be computed in any of several ways. To specify a begin and end x-value in the currently displayed x-axis units, use the parameters brange and erange. If no x-axis range is given, the user is prompted to specify the region of interest using the mouse.
If there is no plot displayed, then brange and erange are assumed to be in units of channel number. If either is not supplied and there is no plot displayed then the full range is used.
Use /chan if brange and range are in channels instead of the currently displayed x-axis units.
