class: MenuObject

class MenuObject(dict=None, /, **kwargs)

Special dict class used to construct a Highcharts menu configuration. Each key represents the identifier of a menu item, while the object is a configuration of that menu item’s settings.

Keys are validated to be valid variable names, while each value is validated to be a MenuItem.

Class Inheritance

clear() → None.  Remove all items from D.

classmethod from_dict(as_dict)

Construct an instance of the class from a dict object.

Parameters:

as_dict (dict) – A dict representation of the object.

Returns:

A Python object representation of as_dict.

Return type:

JavaScriptDict

classmethod from_json(as_json)

Construct an instance of the class from a JSON string.

Parameters:

as_json (str or bytes) – The JSON string for the object.

Returns:

A Python objcet representation of as_json.

Return type:

HighchartsMeta

get(k[, d]) → D[k] if k in D, else d.  d defaults to None.

items() → a set-like object providing a view on D's items

keys() → a set-like object providing a view on D's keys

pop(k[, d]) → v, remove specified key and return the corresponding value.

If key is not found, d is returned if given, otherwise KeyError is raised.

popitem() → (k, v), remove and return some (key, value) pair

as a 2-tuple; but raise KeyError if D is empty.

setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D

to_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 'utf8'.

Returns:

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

Return type:

str or bytes

update([E, ]**F) → None.  Update D from mapping/iterable E and F.

If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v

values() → an object providing a view on D's values

class: MenuItem

class MenuItem(**kwargs)

Configuration for an item that appears in a context menu.

Class Inheritance

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

get_required_modules(include_extension=False) → List[str]

Return the list of URLs from which the Highcharts JavaScript modules needed to render the chart can be retrieved.

Parameters:

include_extension (bool) – if True, will return script names with the '.js' extension included. Defaults to False.

Return type:

list

to_dict() → dict
