Whether to defer displaying the data labels until the initial series animation has finished. If None, behaves as if set to True.

Enable or disable the data labels. Setting to None behaves as if set to False.

Return type:

Return type:

Filter or None

property format: str | None

A format string to apply to the label. Defaults to 'point.value'.

Returns:

The format string to apply to the labels.

Note

Works analogously to DataLabel.formatter().

Warning

Can only be applied only to series which support displaying null points.

Return type:

CallbackFunction or None

property overflow: str | None

Configuration on how to handle a data label that overflows outside of the plot area. Defaults to 'justify', which aligns them inside the plot area. For columns and bars, this means the data label will be moved inside the bar.

Hint

To display data labels outside the plot area, set overflow to 'allow' and DataLabel.crop() to False.

Accepts:

  • 'justify' - which forces the label back into the plot area

  • 'allow' - which allows data labels to overflow outside of the plot area

Note

The overflow treatment is also affected by the DataLabel.crop() setting.

Returns:

Configuration of overflow setting.

Return type:

str or None

property padding: int | None

The padding within the border box when either DataLabel.border_width() or DataLabel.background_color() is set.

Defaults to 5.

Returns:

The padding to apply to the data label.

Return type:

int or None

property position: str | None

Aligns data labels relative to points. Defaults to 'center'.

Accepts the following values:

  • 'left'

  • 'right'

Note

If center is not possible, aligns to right.

Return type:

str

property rotation: int | float | Decimal | None

Warning

Due to a more complex structure, backgrounds, borders and padding will be lost on a rotated data label.

Return type:

numeric or None

property shadow: bool | ShadowOptions | None

If False, no shadow is applied.

  • 'triangle'

  • 'callout'

Returns:

The shape to use for the border around the label.

Return type:

str or None

property style: str | None

CSS styling to apply to the annotation’s label.

The default color setting is "contrast", which is a pseudo color that Highcharts picks up and applies the maximum contrast to the underlying point item, for example the bar in a bar chart.

textOutline is a pseudo property that applies an outline of the given width with the given color, which by default is the maximum contrast to the text. So a bright text color will result in a black text outline for maximum readability on a mixed background. In some cases, especially with grayscale text, the text outline doesn’t work well, in which cases it can be disabled by setting it to "none". When DataLabel.use_html() is True, the textOutline will not be picked up. In this, case, the same effect can be acheived through the text-shadow CSS property.

For some series types, where each point has an extent, like for example tree maps, the data label may overflow the point. There are two strategies for handling overflow. By default, the text will wrap to multiple lines. The other strategy is to set textOverflow to ellipsis, which will keep the text on one line plus it will break inside long words.

Return type:

str or None

property text_path: TextPath | None

Options for a label text which should follow marker’s shape.

Note

Border and background are disabled for a label that follows a path.

Return type:

str or None

property use_html: bool | None

If True, will use HTML to render the data label. If False, will use SVG or WebGL as applicable.

Defaults to False.

Returns:

Flag indicating whether to render data labels using HTML.

Return type:

bool or None

property vertical_align: str | None

The vertical alignment of the annotation’s label. Defaults to None.

If None, the alignment will depend on the data. For example, in a column chart, the label would be above positive values and below negative values.

Accepts:

  • 'bottom'

  • 'middle'

  • 'top'

  • None

Return type:

str or None

property x: int | float | Decimal | None

The x position offset of the label relative to the point. Defaults to 0.

Return type:

numeric or None

property y: int | float | Decimal | None

The y position offset of the label relative to the point. Defaults to None.

Return type:

numeric

property z: int | None

The Z index of the data labels. Defaults to 6.

If None, will be placed above the series.

Use a Z index of 2 to display it behind the series.

Return type:

numeric or None

  • 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 operator: str | None

The operator to compare by. Defaults to None.

Accepts:

  • '>'

  • '<'

  • '>='

  • '<='

  • '=='

  • '==='

Return type:

str or None

property property_: str | None

The point property to filter by. Defaults to None.

Point options are passed directly to properties, additionally there are y value, percentage.

Return type:

str or None

property value: int | float | Decimal | None

The value to compare against. Defaults to None.

Return type:

str or None
