Two problems here : * There is no polygon attribute "set_xy"; it is a method, so you need to call it like "poly.set_xy(xy_new)". In general this is True for all matplotlib set_* methods. There is also an "xy" attribute which you can access like "poly.xy = xy_new". These two approaches do the same thing * The _update_transforms call was a hack I did on CirclePolygon to work around a broken method. it is not a method of Polygon or Patch which is why you are not finding it. For normal usage, the methods that start with underscores are not meant to be called or used at the user level, but because there was breakage in the CirclePolygon set_xy method, I had to hack around it in the example I posted for you. For Polygon, simply setting the xy attribute should be sufficient.
