altair 2.2.2.1

  • adds methods repr_text() and repr_vegalite2() methods for Altair chart objects, allowing them to be rendered natively in Jupyter notebooks using IRKernel (https://irkernel.github.io) (#91, with @flying-sheep).

altair 2.2.2.0

  • new versioning system: first three version numbers follow supported Altair (Python) version

altair 0.0.6

  • adds altair_version(), returns list of versions used for Altair, Vega, Vega-Lite, etc.

  • adds as_chart(), to import a vegaspec as an Altair chart

  • removes rendering functions in favor of a separate package, vegawidget - vegawidget functions imported and exported using templating function vegawidget::use_vegawidget().

  • adds requirement to use reticulate (>=) 1.9, to avoid conflict between data-frame variable-names and python methods (#50, @aliciaschep) and to remove the need to use the r_to_py() function for data (#83)

  • updates to use Altair 2.1.0, which offers tooltips (#29, #46, @aliciaschep)

altair 0.0.5

  • adds compiled option to only_actions() to conform with new option in vega-embed (#71)

  • incorporates remaining galleries

altair 0.0.4

altair 0.0.3

altair 0.0.1.9000

  • new function to manage installation of Altair Python package: install_altair() (#1)

  • makes Vega datasets available through import_vega_data() (#25)

  • significant changes to the rendering function vegalite():

    • if the embed argument is NULL, vegalite() sets it to getOption("altair.embed_options") - if that is not defined, the vega-embed defaults are used

    • width and height arguments to vegalite() are used now to specify the total width and height of rendered charts - notes: (1) this is effective only for single-view charts, (2) width and height apply to the chart only, they do not take into account any action-links - if arguments are not set, the size of the chart is determined from the chart specification (#18)

    • vegalite() strips the style attribute from the <div/> for the htmlwidget - this has the effect of letting the rendered Vega-Lite chart determine the size of its container (#16, #18)

  • adds concatenation operators for charts: |, &, + (#22, @aliciaschep)

  • adds function vega_embed(), with friend only_actions(), to support embedding options in vegalite() (#16)

  • updates css for embedding, makes the action-links look much better (#20, @aliciaschep)

  • adds tooltip-capability to vegalite() renderer, with functions vega_tooltip(), add_fields(), and friends: vega_tooltip_encoding() and vega_tooltip_all() (#4, with @aliciaschep)

  • adds a NEWS.md file to track changes to the package

  • achieves minimal functionality
