[Nicholas Wieland]

Sorry, stupid cut'n paste:
 
class Bar (_DrawingEditorMixin, Drawing):
    def __init__(self, data, width = 120, height = 50, *args, **kwds):
      apply (Drawing.__init__, (self, width, height) + args, kwds)
      self._add (self, HorizontalBarChart (), name = 'chart', validate = None, desc = None)
      self.chart.width = 200
      self.chart.height = 90
      self.chart.x = 350
      self.chart.y = 5
      self.chart.valueAxis.valueMin = -0.4
      self.chart.valueAxis.valueMax = +0.4
      self.chart.categoryAxis.categoryNames = data ['cnames']
      self.chart.data = data ['delta']
      self._add (self, 0, name = 'preview', validate = None, desc = None)
