v4.12.0

Compare Source

Added

• For add_trace, add_shape, add_annotation and add_layout_image, the row and/or col argument now also accept the string "all". row="all" adds the object to all the subplot rows and col="all" adds the object to all the subplot columns. (#​2840)
• Shapes that reference the plot axes in one dimension and the data in another dimension can be added with the new add_hline, add_vline, add_hrect, add_vrect functions, which also support the row="all" and col="all" arguments. (#​2840)
• The add_trace, add_shape, add_annotation, add_layout_image, add_hline, add_vline, add_hrect, add_vrect functions accept an argument exclude_empty_subplots which if True, only adds the object to subplots already containing traces or layout objects. This is useful in conjunction with the row="all" and col="all" arguments. (#​2840)
• For all go.Figure functions accepting a selector argument (e.g., select_traces), this argument can now also be a function which is passed each relevant graph object (in the case of select_traces, it is passed every trace in the figure). For graph objects where this function returns true, the graph object is included in the selection. (#​2844)

Added

• Better magic underscore error messages. For example, some_fig.update_layout(geo_ltaxis_showgrid=True) shows Bad property path:\ngeo_ltaxis_showgrid\n ^ and lists the valid properties for geo.

Updated

• Updated Plotly.js to version 1.57.1. See the plotly.js CHANGELOG for more information. These changes are reflected in the auto-generated plotly.graph_objects module.

Updated

• Updated Plotly.js to version 1.56.0. See the plotly.js CHANGELOG for more information. These changes are reflected in the auto-generated plotly.graph_objects module.

v4.10.0

Compare Source

Added

• Added plotly.io.full_figure_for_development() and plotly.graph_objects.Figure.full_figure_for_development() (#​2737)

Updated

• The JSON serialization of plotly figures had been accelerated by handling
  differently figures with and without NaN and Inf values (#​2880).

Updated

• Updated Plotly.js to version 1.55.2. See the plotly.js CHANGELOG for more information. These changes are reflected in the auto-generated plotly.graph_objects module.
• px.imshow has a new binary_string boolean argument, which passes the
  image data as a b64 binary string when True. Using binary strings allow for
  faster image rendering and smaller figure size. Additional optional arguments
  binary_backend, binary_format and binary_compression_level control
  how to generate the b64 string (#​2691
• px.imshow has a new contrast_rescaling argument in order to choose how
  to set data values corresponding to the bounds of the color range
  (#​2691

Fixed

• Plotly Express no longer converts datetime columns of input dataframes to UTC (#​2749)
• Plotly Express has more complete support for datetimes as additional hover_data (#​2749)
• Histogram selection behaviour with FigureWidget (#​2711) with thanks to @​meffmadd
• Behaviour of full_html() with html=False (#​2469) with thanks to @​tallamjr
• ff.distplot() now only computes traces that will be shown (#​2730) with thanks to @​akbo
• Pandas backend .hist() works with latest version of Pandas (#​2713) with thanks to @​Kerybas

v4.9.0

Compare Source

Added

• Added image export support using Kaleido. The image export backend can be configured using the new engine argument to plotly.io.to_image and plotly.io.write_image. The engine argument may be set to "kaleido", "orca", or "auto". The default is engine="auto", in which case the Kaleido backend is enabled if the kaleido package from PyPI is installed, otherwise Orca is used. (#​2613).
• plotly.express.timeline() added as an official alternative to plotly.figure_factories.create_gantt() (#​2626)
• create_hexbin_mapbox() added to Figure Factories, with thanks to @​RenaudLN for the impressive contribution!
• facet_row_spacing and facet_col_spacing added to Plotly Express cartesian 2d functions (#​2614)
• base added to Plotly Express bar and bar_polar functions (#​2626)
• px.NO_COLOR constant to override wide-form color assignment in Plotly Express (#​2614)

Fixed

• trendline traces are now of type scattergl when render_mode="webgl" in Plotly Express (#​2614)
• regression from 4.8.1 whereby "parent" was not accepted as part of path for px.sunburst() and px.treemap() (#​2640)
• create_dendrogram() figure factory now works correctly with scipy 1.5.1 (#​2627)

Updated

• Updated Plotly.js to version 1.54.6. See the plotly.js CHANGELOG for more information.
• Added all cartesian-2d Plotly Express functions, plus imshow, to Pandas backend with kind option (#​2541)
• plotly.express.imshow now uses data frame index and columns names and values to populate axis parameters by default (#​2539)
• Javascript extensions are now build using Node 12, and have an updated package-lock.json with many fewer security warnings (#​2636)

v4.8.2

Updated

• Updated Plotly.js to version 1.54.5. See the plotly.js CHANGELOG for more information.
• add_traces() now accepts bare int-like values for rows/cols as well as lists thereof (#​2546), with thanks to @​MCBoarder289 for the contribution!

Fixed

• row/col now accept int-like values, not strictly int values (#​2451), with thanks to @​MCBoarder289 for the contribution!
• Fixed special cases with px.sunburst and px.treemap with path input (#​2524)
• Fixed bug in hover_data argument of px functions, when the column name is changed with labels and hover_data is a dictionary setting up a specific format for the hover data (#​2544).
• Made the Plotly Express trendline argument more robust and made it work with datetime x values (#​2554)
• Fixed bug in px.sunburst and px.treemap: when the color and values arguments correspond to the same column, a different aggregation function has to be used for the two arguments (#​2591)
• Plotly Express wide mode now accepts mixed integer and float columns (#​2598)
• Plotly Express range_(x|y) should not impact the unlinked range of marginal subplots (#​2600)
• px.line now sets line_group=<variable> in wide mode by default (#​2599)
• Corrected some regex warnings (#​2577), with thanks to @​georgevdd for the contribution!

v4.8.1

Added

• plotly now provides a Plotly Express-backed Pandas-compatible plotting backend, which can be activated via pandas.options.plotting.backend = "plotly". Note that it is not intended to implement every Pandas plotting function, nor is it intended to replicate the behavio
