| "To avoid re-writing the matplotlib rendering engine in a browser compatible language (i.e. JavaScript), the nbagg backend requires a live IPython session for interactive figures. Notice however that in this static rendering of the notebook, we have a static image of the figure, akin to the existing IPython \"inline\" backend. As with the \"inline\" backend, it is only the snapshot of the figure which is preserved, rather than the figure instance itself (the ability to pickle a figure does make that a possibility though) - essentially, what this means is that we have an opportunity to interact with out data before the figure is cast in stone as an image.\n", | |
| "\n", | |
| "## Features\n", | |
| "\n", | |
| "The \"nbagg\" backend has some pretty unique features which have the potential to be built upon in the future.\n", | |
| "\n", | |
| "One interesting feature of a nbagg figure is that it can be displayed multiple times, with all views on the figure being updated simultaneously (even accross different browsers), so there is a real potential for some collaborative figure investigation when the concept of shared users becomes a reality in the notebook.\n", | |
| "\n", | |
| "I'm keen to make this backend easy to extend such that its easy to add things such as an \"export to mpld3\" button, some snapshotting functionality so that notebook viewers can see multiple views of the same figure in a slideshow and I'm sure there is a whole host of other cool functionality that could be added.\n", | |
| "\n", | |
| "Let me know what you think? Got any ideas on how to make this backend even better? Get in touch in the comments section." | |
