You can add any number of objects to a Drawing - titles, legends, charts
etc.  Just add a String node and call it title e.g.

	d = Drawing()
	vbc = VerticalBarChart()

	#add it to the drawing.
	d.add(vbc, name='chart')
         #now refer to it...
	d.chart.x = 50

	#add a String object as the title
	d.add(String(180,180, "Profits for February"), name="title")
   	#now customize it further
	d.title.fontName = 'Helvetica-Bold'


Hope this helps,
