Hi Alex,

> Is there a way to "continue" an MP figure? Like keeping the axes, etc. and just adding code to the figure?

Buffers might be what you want. From the MetaFun manual:

> Buffers can be used to stepwise build graphics. By putting code in multiple buffers, you can selectively process this code. [p.124]

Hope that helps.
