copy(other=None, overwrite=True, **kwargs)

Copy the configuration settings from this instance to the other instance.

Parameters:

other (HighchartsMeta) – The target instance to which the properties of this instance should be copied. If None, will create a new instance and populate it with properties copied from self. Defaults to None.
overwrite (bool) – if True, properties in other that are already set will be overwritten by their counterparts in self. Defaults to True.
kwargs – Additional keyword arguments. Some special descendents of HighchartsMeta may have special implementations of this method which rely on additional keyword arguments.

Returns:

A mutated version of other with new property values

classmethod from_dict(as_dict: dict, allow_snake_case: bool = True)

Construct an instance of the class from a dict object.

Parameters:

as_dict (dict) – A dict representation of the object.
allow_snake_case (bool) – If True, interprets snake_case keys as equivalent to camelCase keys. Defaults to True.

Returns:

A Python object representation of as_dict.

Return type:

HighchartsMeta

classmethod from_js_literal(as_str_or_file, allow_snake_case: bool = True, _break_loop_on_failure: bool = False)

Return a Python object representation of a Highcharts JavaScript object literal.

Parameters:

as_str_or_file (str) – The JavaScript object literal, represented either as a str or as a filename which contains the JS object literal.
allow_snake_case (bool) – If True, interprets snake_case keys as equivalent to camelCase keys. Defaults to True.
_break_loop_on_failure (bool) – If True, will break any looping operations in the event of a failure. Otherwise, will attempt to repair the failure. Defaults to False.

Returns:

A Python object representation of the Highcharts JavaScript object literal.

Return type:

HighchartsMeta

classmethod from_json(as_json_or_file, allow_snake_case: bool = True)

Construct an instance of the class from a JSON string.

Parameters:

as_json_or_file – The JSON string for the object or the filename of a file that contains the JSON string.
allow_snake_case (bool) – If True, interprets snake_case keys as equivalent to camelCase keys. Defaults to True.

Returns:

A Python objcet representation of as_json.

Return type:

HighchartsMeta

to_dict() → dict

Generate a dict representation of the object compatible with the Highcharts JavaScript library.

Note

The dict representation has a property structure and naming convention that is intentionally consistent with the Highcharts JavaScript library. This is not Pythonic, but it makes managing the interplay between the two languages much, much simpler.

Returns:: A dict representation of the object.
Return type:: dict

to_js_literal(filename=None, encoding='utf-8') → str | None

Return the object represented as a str containing the JavaScript object literal.

Parameters:

filename (Path-like) – The name of a file to which the JavaScript object literal should be persisted. Defaults to None
encoding (str) – The character encoding to apply to the resulting object. Defaults to 'utf-8'.

Return type:

str or None

to_json(filename=None, encoding='utf-8')

Generate a JSON string/byte string representation of the object compatible with the Highcharts JavaScript library.

Note

This method will either return a standard str or a bytes object depending on the JSON serialization library you are using. For example, if your environment has orjson, the result will be a bytes representation of the string.

Parameters:

filename (Path-like) – The name of a file to which the JSON string should be persisted. Defaults to None
encoding (str) – The character encoding to apply to the resulting object. Defaults to 'utf-8'.

Returns:

A JSON representation of the object compatible with the Highcharts library.

Return type:

str or bytes

static trim_dict(untrimmed: dict, to_json: bool = False) → dict

Remove keys from untrimmed whose values are None and convert values that have .to_dict() methods.

Parameters:

untrimmed (dict) – The dict whose values may still be None or Python objects.
to_json (bool) – If True, will remove all keys from untrimmed that are not serializable to JSON. Defaults to False.

Returns:

Trimmed dict

Return type:

dict

static trim_iterable(untrimmed, to_json=False)

Convert any EnforcedNullType values in untrimmed to 'null'.

Parameters:

untrimmed (iterable) – The iterable whose members may still be None or Python objects.
to_json (bool) – If True, will remove all members from untrimmed that are not serializable to JSON. Defaults to False.

Return type:

iterable

property enabled: bool | None

If True, markers are enabled. If False, markers are disabled. If None, markers are hidden when the data is dense and shown for more widespread data points.

Defaults to None

Return type:: bool or None

property enabled_threshold: int | None

The threshold for how dense the point markers should be before they are hidden, assuming that Marker.enabled() is None. Defaults to 2.

The number indicates the horizontal distance between the two closest points in the series, as multiples of the Marker.radius(). In other words, the default value of 2 means points are hidden if overlapping horizontally.

Return type:: int or None

property fill_color: str | Gradient | Pattern | None

The fill color or gradient for the marker. Defaults to None, which causes the series’ or point’s color to be used.

Returns:: The fill color for the marker.
Return type:: str, Gradient, Pattern`, or None

property height: int | float | Decimal | None

Explicitly set the height of an image marker. Defaults to None.

Warning

Only applies to image markers. When setting this property, Marker.width() must also be set.

Return type:: numeric or None

property line_color: str | Gradient | Pattern | None

The line color or gradient for the marker’s outline. Defaults to '#ffffff'.

Returns:: The line color for the marker.
Return type:: str, Gradient, Pattern`, or None

property line_width: int | float | Decimal | None

The line width (in pixels) applied to the marker’s border. Defaults to 0.

Returns:: The line width to apply to the marker’s border.
Return type:: numeric or None

property radius: int | float | Decimal | None

The radius applied to the point marker. Defaults to 4.

Returns:: The radius to apply to the point marker.
Return type:: numeric or None

property states: States | None

States for a single point marker.

Return type:: States or None

property symbol: str | None

A predefined shape or symbol for the marker. Defaults to None.

When None, the symbol is pulled from (JavaScript) options.symbols. Other possible values are:

'circle'

'square'

'diamond'

'triangle'

'triangle-down'

Additionally, the URL to a graphic can be given using the form: 'url(graphic.png)'.

Note

For an image marker to be applied to exported charts, its URL needs to be accessible by the export server.

Return type:: str or None

property width: int | float | Decimal | None

Explicitly set the width of an image marker. Defaults to None.

Warning

Only applies to image markers. When setting this property, Marker.height() must also be set.

Return type:: numeric or None
