  🔄 Changed

  • 💥 [breaking change] New Geocoding API!

  Since Lets-Plot v2.0.0 the peviouse Geocoding API is no longer working (hence we bumped the version to 2.0.0).

  The old version of the Geocoding backend remains on-line for a couple of release cycles to continue support of prior versions of Lets-Plot.

  To learn more about Geocoding API see: Geocoding.

  • ⬆️ The project upgraded to Kotlin v1.4.21 (was v1.4.10).

  🛠 Fixed

  • Kernel density estimate computation is too slow.
  • 🚑 Serialize NaN and other special values as None (CRITICAL for the "Lets-Plot in SciView" PyCharm plugin) [#282].
  • 🏗 Error in plot building: 'trans' parameter not compatible with None values in data [#287].
  • LOESS smoothing fails on small (<3) number points.
  • Facet grid truncated in jupyter [#28].
  • The reverse parameter on discrete scale with 'limits' [#303].
  • Geocoder's allow_ambiguous() doesn't prevent "ValueError: Multiple objects.." [#174].
  • 🛠 Fix tooltip for overlapping objects [#230].
  • 🛠 Fix duplicate values in tooltip [#280].
  • geom_histogram should not try to handle geometries in GeoDataFrame [#281].
  • 🏗 Error building plot: Layer 'MAP' is not supported on Live Map. [#285].
  • Align title to the left of the plot geom area [#289].
  • Tooltip on geom_ribbon().

• v1.5.6 Changes

  December 23, 2020

  🛠 Fixed

  • 🍎 “Symbol not found: _NSGenericException” error on macOS [#276].

• v1.5.5 Changes

  December 18, 2020

  ➕ Added

  • Correlation plot.

  See: The 'bistro' Package.

  • 'No Javascript' mode.

  Support for notebook renderers that don't execute Javascript.

  See: 'No Javascript' mode

  • In tooltip customization API:
    • options: center and middle (anchor).
    • option 'minWidth'.

  See: Tooltip Customization.

  • 'na_text' parameter in 'geom_text'

  🔄 Changed

  • Tooltip customization API:
    • The anchor option moved from theme to layer: python geom_xxx(tooltips=layer_tooltips().anchor(anchor_value)) where anchor_value: ['top_right'|'top_center'|'top_left'|'bottom_right'|'bottom_center'|'bottom_left'|'middle_right'|'middle_center'|'middle_left'].

  See: Tooltip Customization.

  🛠 Fixed

  • Tooltip should appear when the mapped data is continuous [#241]
  • Tooltip 'null' displayed for undefined vals [#243]
  • Y-tooltip should be aligned with a tile center [#246]
  • With facet_grid tooltip shows data from last plot on all plots [#247]

• v1.5.4 Changes

  November 19, 2020

  🔄 Changed

  • 💥 [breaking change] In functions format(field, format) and line(template) in 🏗 tooltip builder, the '$' symbol is no longer used in aesthetic reference. It was replaced by the '^' (hat) symbol 👀 (see the udated doc: Tooltip Customization).

• v1.5.3 Changes

  November 05, 2020

  ➕ Added

  • 👀 Facilities for customization of tooltip contents and its position (see Tooltip Customization).
  • attribution and other new parameters in the maptiles_zxy() function.
  • label_format parameter in the geom_text() function.
  • scale_x_discrete_reversed() / scale_y_discrete_reversed()
  • ggsave() function (only SVG, HTML)

  🛠 Fixed

  • Mercator's projection computes coordinates incorrectly (geom_map(), coord_map())
  • 🛠 Handling of xlim,ylim in coord_fixed(), coord_map()
  • Colorbars: take in account limits defined in continuous color/fill scales.
  • scale_color_hue incorrectly interprets chroma range [#206].
  • scale_color_brewer shouldn't fail if 'type' is not specified [#203].

  • 0️⃣ Default discrete color scheme is now ColorBrewer's Set2 (was Dark2)

  🗄 Deprecated

  • Function gg_image_matrix(). The new function is: image_matrix() in the lets_plot.bistro.im module. The new function is not any longer displaying matrix by itself but returns a GGBunch object instead. Unlike the depricated gg_image_matrix() function, it is not imported by from lets_plot import * statement.

  Usage:

     from lets_plot.bistro.im import image_matrix
     image_matrix()
