plotly v3.4.0 Release Notes

Release Date: 2018-11-02 // over 5 years ago

  • ⚡️ 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)
