You have properties and/or events with the same name as class and you 
have to rename those
in Transforms\Metadata.xml
with following:

Renaming class:
   <attr
path="/api/package[@name='org.achartengine.tools']/class[@name='Pan']"
     name="managedName"
     >PanWrapper</attr>


Renaming event by adding eventName attribute:
   <attr
path="/api/package[@name='org.achartengine.tools']/class[@name='Pan']/method[@name='addPanListener']"
     name="eventName"
   >Panned</attr>


Renaming property by adding propertyName attribute:
   <attr
path="/api/package[@name='org.achartengine.tools']/class[@name='Pan']/method[@name='addPanListener']"
     name="propertyName"
   >Panned</attr>


To prevent binding of property/event - set the event/property name to 
the empty string.

If You need sample I can push AChartEngine bindign to github. I didn't 
have neought time
since I finished it, but if You need really bad it let me know.
