Release 1.4.0

  • MAJOR performance gains in the .to_js_literal() method. Implementation seems to improve performance by 50 - 90%.
  • SIGNIFICANT performance gains in the .to_json() method. Implementation seems to improve performance by 30 - 90%.
  • ENHANCEMENT: Significantly simplified use of the .from_pandas() method to support:
    • creation of multiple series from one DataFrame in one method call
    • creation of series without needing to specify a full property map
    • support for creating series by DataFrame row, rather than just by DataFrame column
  • ENHANCEMENT: Added the .from_pandas_in_rows() method to support creation of charts and series from simple two-dimensional DataFrames laid out in rows.
  • ENHANCEMENT: Added one-shot chart creation and rendering from Series objects.
  • ENHANCEMENT: Added one-shot chart creation using series and data/series_type keywords.

  • BUGFIX: Fixed instability issues in Jupyter Notebooks, both when operating as a Notebook (outside of Jupyter Lab) and when saved to a static HTML file.

Release 1.3.0

  • ENHANCEMENT: Modified the way that data points are serialized to JavaScript literal objects. Now, they are serialized to a JavaScript array if their configured properties are those that Highcharts (JS) supports in JavaScript array notation. Otherwise, the code falls back to serialize the data point as a JavaScript object literal. This change is intended to improve performance and reduce the size of the serialized data. (#27)

  • ENHANCEMENT: Added __str__() method with special handling for difficult-to-read classes.

  • BUGFIX: Fixed incorrect serialization of EnforcedNull in .to_dict() and .to_json().

Release 1.2.1

  • BUGFIX: Fixed incorrect datetime serialization to SECONDS from Unix epoch. Now serializing to JS-compatible MILLISECONDS from Unix epoch.
