NAME: tclip PURPOSE: Wrapper for xclip.pro allowing input of tplot variable names. IMPORTANT NOTE: The Y values of the tplot variable are cliped using tclip, Not Time. TO clip the time range of a tplot variable, use the program TIME_CLIP.PRO. CALLING SEQUENCE: tclip, varnames, amin, amax, _extra=_extra INPUT: varnames = an array (or scalar) of tplot variable names amin, amax = the minumum and maximum values KEYWORDS: flag = the value that clipped data are set to, the default is -0.0/0.0 (NaN) newname = if set,give these names to the clipped data, the default is to append '_clip' to the input names and pass out the names in the newname variables, Unless /overwrite is set. This will not work for wild card input. overwrite = if set, write the new data back to the old tplot variables, do not set this with newname display_object = Object reference to be passed to dprint for output.
