Would i be right in assuming that it would take roughly the same amount of effort as writing a new backend? ie for each motplotlib action it would need a function to store that action and a function to call that action again. > and most of us don't see a compelling need; we believe that a > better practice is to structure one's work so that plotting is separated > from data (result) generation in any cases where the latter is highly > time-consuming. It might not be essential, but it would offer an additional work flow, that a few people seem to like. I think it would be especially useful when it comes to putting plots into papers. I often find that i want to tweak something like the font size or labels. having a modifiable plot format seems the easiest way to achieve that. maybe the could even be some integration into latex so that if you were to resize your plot in your paper, it would be re-rendered with the fonts adjusted. >>> I'd like a way for saving a plot from from matplotlib, so that it can be >>> re-rendered later, possibly with a different backend, maybe to a different >>> size, and maybe with changes to the labels.
