 ### Added
 - new artists submodule `animate` as a convenient wrapper for matplotlib's `FuncAnimate`
-- `quick2Ds` and `quick1Ds`: like `quick2D` and `quick1D`, but iterator based
 - `animate.animate2D`: allows versatile conversion of data to animation.
 - `animate.animate_interact2D`: create an animation from an interact2D object.
-- `animate.animate_quick2D`: create an animation whose frames are the figures that would be created in a quick2D call
+- `Quick2DIterator`, `Quick1DIterator`: iterator classes for making figures for each object in a data chop.
+- `quick2Ds` and `quick1Ds`: like `quick2D` and `quick1D`, but wrap the iterator classes.
+- `animate.animate_quick`: create an animation whose frames are the figures that would be created in a quick1Ds/quick2Ds call.
 
 ### Changed
 - `interact2D`: replaced SimpleNamespace object with a dataclass for more explicit typing
-- `quick2D`: `__iter__` method added which modifies the same figure over and over instead of writing new figures for each chop object
+- `quick1D`, `quick2D`:  refactored for integration with iterators, animations (these functions are wrappers for the class `Quick1DLegacy`, `Quick2DLegacy`).
 
 ### Fixed
 - `Data.squeeze`: axes of output object now inherit units from axes of the input object
