Now I'm using DragNode charts to show a topology. The default label is smaller than what I expected. In docs,It seems that  "baseFont" and"baseFontSize" work. but when I define "baseFontSize" in my xml, the toolTexts change,but the  labels remain, the followed is my xml code. 
  
------------------------------------------------------------------------------------- 
  
 
 
      chart palette='2' xAxisMinValue='0' xAxisMaxValue='100'
yAxisMinValue='0' yAxisMaxValue='100' showformbtn='0' viewMode='1'
allowDrag='0' showToolTip='0' baseFont='Verdana' baseFontSize='12'>
dataset plotBorderAlpha='1' showPlotBorder='1' showformbtn='0'
	allowDrag='0'>
	set x='70' y='20' label='database' color='FFFFFF' id='db1'    width='80'	height='88' imageNode='1' imageWidth='40' ageHeight='40'
		imageurl='/fusion/db.png'
		labelAlign='bottom' imageAlign='middle' alpha='0' />
 
  
------------------------------------------------------------------------------------- 
  
 I don't know  how I can change the fontsize of label.  
  
  
  
thanks for suggestion
