; @keyword COLORS {type=vector}
; A vector, the same size as VALUES, containing the color index
; to be used for each bar.  If not specified, the colors are
; selected based on spacing the color indices as widely as
; possible within the available colors (specified by D.N_COLORS).

; @keyword COLORS {type=integer}
; I gives color of all colorbars. (contrarily to colors
; which is a vector giving the color of each colorbar).

@common
; 1) I reinitialize the graphic environment (variables !x, !y and !p):
   if NOT keyword_set(NOREINITPLT) then reinitplt, _extra = ex
; 2) I place the drawing on the screen like on the postscript
   IF chkstru(ex, 'overplot')EQ 0 THEN placedessin, 'autre', _extra = ex
; 3) Drawing
   if n_elements(COLORS) NE 0 then BEGIN
      if n_elements(COLORS) EQ n_elements(Values) then col = colors $
       ELSE col = replicate(colors[0], n_elements(Values))
   ENDIF ELSE col = congrid(indgen(!d.n_colors < 256), n_elements(Values))
;
   bar_plot, Values, background = !p.background, colors = col $
             , xstyle = 1, ystyle = 1, _extra = ex
; 4) End of drawing
   terminedessin, _extra=ex
