[3.4.0] - 2018-11-02

Updated

  • Updated Plotly.js to version 1.42.2. Select highlights included below, see
    the plotly.js CHANGELOG for more information.

Added

  • Default figure properties may now be customized using figure
    templates (themes) and 7 new predefined templates are bundled with
    plotly.py
    (#1224)
  • Added Parallel Categories (parcats) trace type for the visualization
    of multi-dimensional categorical datasets
    (plotly/plotly.js#2963)
  • Added LaTeX typesetting support for figures displayed in the Jupyter
    Notebook using plotly.offline.iplot and plotly.graph_objs.FigureWidget.
    Note: There are still outstanding issues with MathJax rendering in FireFox,
    but it is now working well in Chrome.
    (#1243)
  • Added include_mathjax argument to plotly.offline.plot to support
    the creation of HTML files with LaTeX typesetting
    (#1243)
  • Added new plotly.offline.get_plotlyjs function that returns the
    contents of the bundled plotly.js library as a string
    (#637,
    #1246)
  • Added new plotly.offline.get_plotlyjs_version function that returns
    the version of the bundled plotly.js library
    (#1246)
  • HTML div strings returned by plotly.offline.plot now contain logic
    to automatically resize the figure responsively. This logic was previously
    only added for html files.
    (#1043,
    #1234)
  • Figures displayed using plotly.offline.iplot in the classic Jupyter
    Notebook will now resize responsively
    (#1234)
  • Added 'cdn', 'directory', and path string include_plotlyjs options
    in plotly.offline.plot
    (#1234)
    • When 'cdn', the resulting html file/div includes a script tag reference
      to the plotlyjs cdn.
    • When 'directory', the resulting html file/div includes a script tag
      reference to a plotly.min.js bundle in the same directory as the html file.
      If output_type is 'file' then this plotly.min.js bundle is created in
      the output directory if it doesn't already exist.
    • When a string ending with '.js', the resulting html file/div includes
      a script tag that references this exact path. This can be used to point
      to a plotly.js bundle from an alternative CDN.
  • Added a new color_threshold argument to the create_dendrogram figure
    factory to control the dendrogram clustering cutoff
    (#995,
    #1075,
    #1214)
  • Added support for autorange='reversed' in 3D axes
    (#803,
    plotly/plotly.js#3141)
  • Added new gl3d tick and title auto-rotation algorithm that limits text
    overlaps
    (plotly/plotly.js#3084,
    plotly/plotly.js#3131)
  • Added modebar layout style attributes:
    orientation, bgcolor, color and activecolor
    (plotly/plotly.js#3068,
    plotly/plotly.js#3091)
  • Added title, titleposition and titlefont attributes to pie traces
    (plotly/plotly.js#2987)
  • Added hoverlabel.split attribute to ohlc and candlestick traces to
    split hover labels into multiple pieces
    (plotly/plotly.js#2959)
  • Added support for line.shape values 'hv', 'vh', 'hvh'
    and 'vhv' in scattergl traces
    (plotly/plotly.js#3087)
  • Added trace, node and link hoverinfo for sankey traces
    (#3096,
    #3150)
  • Added per-sector textfont settings in pie traces
    (#3130)

Changed

Fixed

  • Plotly's use of MathJax for LaTeX typesetting no longer interferes with
    the Jupyter Notebook's use of MathJax
    (#445,
    #360)
  • Fixed several issues with the use of reversescale=True in the
    create_annotated_heatmap figure factory
    (#1251)
  • Fixed case where plotly.offline.iplot would fail to render in the classic
    Jupyter Notebook if the notebook contained a Markdown headline with the text
    "Plotly"
    (#816)
  • None values in a scatter.hovertext list are now omitted from the
    hover label rather than being displayed as the string "None"
    (#1244)
  • Subplot titles created by plotly.tools.make_subplots are now positioned
    properly when custom row_width/column_width arguments are specified
    (#1229)
  • The bar.width property may now be specified as a numpy array or a pandas
    series
    (#1231,
    plotly/plotly.js#3169)
  • Error bars are now scaled correctly for logarithmic scatter3d traces
    (#1139)
  • Use uuid.uuid4 rather than uuid.uuid1 to work around an upstream
    Python bug
    (#1235,
    #1236)
  • The layout.grid.subplots property may now be specified as a 2D list of
    subplot identifiers
    (#1220,
    #1240)
  • Fixed scatter3d text alignment
    (#1055,
    plotly/plotly.js#3180)
