Re: [PyX-devel] graph.data.points and iterables

[André W. <wo...@us...>]

Gert,

Thank you for the suggestion. You're right, and we should probably rethink the data handling. It is rather old code, and its design probably predates the Python 2.2 release, where iterators have been introduced. At least it was working on older Python versions for many years. I'm making myself a note and we can probably address this in one of the next releases.

Best,


André
