Changelog

pyobsplot 0.5.2-dev

Plot.plot() performance should now be equivalent to the one of a generator object
New shortcut syntax Plot.line(...).plot() is now available (#18, thanks @harrylojames)
Bugfix: typst error with certain decimal padding values.

The plot generator API has been changed. Generators are no more defined with a renderer argument, a format is specified instead. This format can either be widget, html, svg or png. So renderer="widget" is replaced by format="widget" (which is the default), whereas renderer="jsdom" is replaced by format="html" or one of the new format="svg" and format="png".
The “kwargs” alternative syntax is now deprecated and will generate errors. Plots must be defined either by passing a specification dictionary, or a call to a Plot.xxx method.

Plots can now be generated in “svg” and “png”, and saved as “svg”, “png” or “pdf”. This is done by converting figures using typst. Many thanks to @wirhabenzeit and @harrylojames for the idea, the underlying code and the feedback.
