- Update to version 3.5.0
+ Updated
* Updated Plotly.js to version 1.43.1. See the
plotly.js CHANGELOG](https://github.com/plotly/plotly.js/blob/master/CHANGELOG.md#1431----2018-12-21)
or more information.
+ Changed
* Plotly.js 1.43 converted `title` properties (e.g. `layout.title`) from
trings into compound objects that contain the text as the `text` property
long with new title placement attributes `x`, `y`, `xref`, `yref`, `xanchor`,
yanchor` and `pad`. Plotly.py 3.5.0 follows the new schema, but still
upports specifying `title` as a string, in which case the string is assigned
o the `title.text` property
[#1302](https://github.com/plotly/plotly.py/issues/1302))
* Plotly.js 1.43 also moved existing `title*` properties
e.g. `layout.titlefont`) under the `title` object (e.g. `layout.title.font`).
lotly.py 3.5.0 follows the new schema, but still
upports the legacy `title*` properties by mapping them to the corresponding
title.*` property
[#1302](https://github.com/plotly/plotly.py/issues/1302))
* The `update` method on `graph_objs` now returns the updated object in order
o support chaining multiple update operations together
[#1379](https://github.com/plotly/plotly.py/issues/1379))
* The `show_link` option has been set to `False` by default in the offline
plot` and `iplot` functions. Now that the "send data to cloud" button has
een disabled by default in plotly.js 1.43.0, no buttons/links will be
isplayed by default that result in data being sent off of the local machine
[#1304](https://github.com/plotly/plotly.py/issues/1304))
* `config` options that are not known by plotly.py result in a warning but are
till passed along to plotly.js. Prior to this change these unknown options
ere dropped silently
[#1290](https://github.com/plotly/plotly.py/issues/1290))
* Built-in themes now specify colorscales using the new global
layout.colorscale` properties. Previously the colorscales were defined for
ach trace type individually. This reduces the size of the resulting theme
iles
[#1303](https://github.com/plotly/plotly.py/issues/1303))
* Increased the maximum retry time of the orca integration from 8s to 30s
[#1297](https://github.com/plotly/plotly.py/issues/1297))

* Fix orca error when the `ELECTRON_RUN_AS_NODE` environment variable is set
[#1293](https://github.com/plotly/plotly.py/issues/1293))
* The `'responsive'` config key was being silently blocked
[#1290](https://github.com/plotly/plotly.py/issues/1290))
* Fixed error when using unicode characters in string properties on Python 2
[#1289](https://github.com/plotly/plotly.py/issues/1289))
* Removed invalid calls to non-existent `validate` and `strip_style` `Figure`
ethods in matplotlylib conversion logic
[#1128](https://github.com/plotly/plotly.py/issues/1128))
- Update to version 3.4.2
+ Fixed
* `config` options are now supported when using `plotly.offline.iplot` to
isplay a figure in JupyterLab. Requires version 0.18.1 of the
@jupyterlab/plotly-extension` extension.
[#1281](https://github.com/plotly/plotly.py/pull/1281),

+ JupyterLab Versions
For use with JupyterLab, the following versions of the following packages
must be installed:
* Python Packages
> plotly==3.3.0
> ipywidgets>=7.2
> notebook>=5.3
> jupyterlab==0.34
* JupyterLab Extensions
> plotlywidget@0.4.0
> @jupyter-widgets/jupyterlab-manager@0.37
> @jupyterlab/plotly-extension@0.17
- Update to version 3.2.1
This is a patch release that fixes a few bugs and reintroduces a few
version 2 features that were not supported in version 3.
The bundled version of plotly.js remains at 1.40.1
+ JupyterLab Versions
For use with JupyterLab, the following versions of the following packages
must be installed:
* Python Packages
> plotly==3.2.1
> ipywidgets>=7.2
> notebook>=5.3
> jupyterlab==0.34
* JupyterLab Extensions
> plotlywidget@0.3.0
> @jupyter-widgets/jupyterlab-manager@0.37
> @jupyterlab/plotly-extension@0.17
+ Added
* An optional `skip_invalid` argument has been added to the `Figure` and
FigureWidget` constructors. By default, `skip_invalid` is `False` and invalid
igure properties will result in an exception (this is identical to the
revious behavior). When `skip_invalid` is set to `True`, invalid properties
ill instead be silently ignored. This argument replaces the `_raise`
rgument that was available in version 2, and makes it possible to import
igure definitions from different plotly versions, where incompatible
roperties are ignored rather than causing an exception.
* A `to_ordered_dict` method has been added to the `Figure` and `FigureWidget`
lasses. This method returns a representation of the figure as a nested
tructure of `OrdererdDict` and `list` instances where the keys in each
OrderedDict` are sorted alphabetically. This method replaces the
get_ordered` method that was available in version 2, and makes it possible
o traverse the nested structure of a figure in a deterministic order.
+ Fixed
* Pandas `Series` and `Index` objects storing `datetime` values were
incorrectly cast to numeric arrays
([plotly/plotly.py#1160](https://github.com/plotly/plotly.py/issues/1160),
[plotly/plotly.py#1163](https://github.com/plotly/plotly.py/pull/1163))
* Numpy arrays with `uint64` datatype caused a `FigureWidget` error,
and no figure was displayed
([plotly/plotly.py#1155](https://github.com/plotly/plotly.py/issues/1155),
[plotly/plotly.py#1163](https://github.com/plotly/plotly.py/pull/1163))

Note: This release's installation was broken. It has been removed from PyPI
- Update to version 3.0.0
This is a major version with many exciting updates.
+ JupyterLab plotlywidget version: 0.1.1
+ Plotly.js version: 1.38.3
+ Added
* Full Jupyter ipywidgets integration with the new `graph_objs.FigureWidget` class
* `FigureWidget` figures can be updated interactively using property assignment syntax
* The full trace and layout API is generated from the plotly schema to provide a great experience for interactive use in the notebook
* Support for setting array properties as numpy arrays. When numpy arrays are used, ipywidgets binary serialization protocol is used to avoid converting these to JSON strings.
* Context manager API for animation. Run `help(go.Figure().batch_animate)` for the full doc string.
* Perform automatic retries when communicating with plot.ly services. This introduces a new required dependency on the [retrying](https://pypi.org/project/retrying/) library.
* Improved data validation covering the full API with clear, informative error messages. This means that incorrect properties and/or values now always raise a `ValueError` with a description of the error, the invalid property, and the available properties on the level that it was placed in the graph object. Eg. `go.Scatter(foo=123)` raises a validation error. See https://plot.ly/python/reference/ for a reference to all valid properties and values in the Python API.
* Error message for `plotly.figure_factory.create_choropleth` is now helpful to Anaconda users who do not have the correct modules installed for the County Choropleth figure factory.
