octave: Bar Series

 
 15.4.6.3 Bar Series
 ...................
 
 Bar series objects are created by the ‘bar’ or ‘barh’ functions.  Each
 ‘hggroup’ element contains a single patch object.  The properties of the
 bar series are
 
 ‘showbaseline’
 ‘baseline’
 ‘basevalue’
      The property ‘showbaseline’ flags whether the baseline of the bar
      series is displayed (default is "on").  The handle of the graphics
      object representing the baseline is given by the ‘baseline’
      property and the y-value of the baseline by the ‘basevalue’
      property.
 
      Changes to any of these properties are propagated to the other
      members of the bar series and to the baseline itself.  Equally,
      changes in the properties of the base line itself are propagated to
      the members of the corresponding bar series.
 
 ‘barwidth’
 ‘barlayout’
 ‘horizontal’
      The property ‘barwidth’ is the width of the bar corresponding to
      the WIDTH variable passed to ‘bar’ or BARH.  Whether the bar series
      is "grouped" or "stacked" is determined by the ‘barlayout’ property
      and whether the bars are horizontal or vertical by the ‘horizontal’
      property.
 
      Changes to any of these property are propagated to the other
      members of the bar series.
 
 ‘linewidth’
 ‘linestyle’
      The line width and style of the edge of the patch objects making up
      the bars.  SeeLine Styles.
 
 ‘edgecolor’
 ‘facecolor’
      The line and fill color of the patch objects making up the bars.
      SeeColors.
 
 ‘xdata’
      The nominal x positions of the bars.  Changes in this property and
      propagated to the other members of the bar series.
 
 ‘ydata’
      The y value of the bars in the ‘hggroup’.
 
 ‘xdatasource’
 ‘ydatasource’
      Data source variables.
