Add a volume overlay to the current axes.  The closes are used to
determine the color of the bar.  -1 is missing.  If a value is
missing on one it must be missing on all

ax          : an Axes instance to plot to
width       : the bar width in points
colorup     : the color of the lines where close >= open
colordown   : the color of the lines where close <  open
alpha       : bar transparency
