[reportlab-users] HorizontalBarChart(), align, categoryAxis.categoryNames

[Robin Becker]

Hi Helga,

you can try something like this


> from reportlab.graphics.charts.barcharts import HorizontalBarChart

> from reportlab.graphics.shapes import Drawing, _DrawingEditorMixin

>

> 	def __init__(self,width=400,height=200,*args,**kw):

> 		Drawing.__init__(self,width,height,*args,**kw)

> 		self._add(self,HorizontalBarChart(),name='chart',validate=None,desc=None)

> 		self.chart.y                = 20

> 		self.chart.x                = 100

> 		self.chart.width            = self.width -self.chart.x -10

> 		self.chart.height           = self.height -self.chart.y -10

> 		self.chart.categoryAxis.style='stacked'

> 		self.chart.categoryAxis.categoryNames        = 'AAAA','BBBBBBBBBBB','CC','DDDDDDDDDDDDDDD'

> 		self.chart.categoryAxis.labels.fontName         = 'Helvetica'

> 		self.chart.categoryAxis.labels.fontSize         = 6

> 		self.chart.categoryAxis.labels.boxTarget='lo'

> 		self.chart.categoryAxis.labels.boxAnchor='w'

> 		self.chart.categoryAxis.labels.dx               = -90

effectively we turn the boxAnchor the wrong way and then adjust the anchor 
position with the generic label dx
