.item
class: ItemOptions
- class ItemOptions(**kwargs)[source]
General options to apply to all Item series types.
An item chart is an infographic chart where a number of items are laid out in either a rectangular or circular pattern. It can be used to visualize counts within a group, or for the circular pattern, typically a parliament.
The circular layout has much in common with a pie chart. Many of the item series options, like
center
,size
and data label positioning, are inherited from thePlotOptions.pie()
series and don’t apply for rectangular layouts.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. IfNone
, will create a new instance and populate it with properties copied fromself
. Defaults toNone
.overwrite (
bool
) – ifTrue
, properties inother
that are already set will be overwritten by their counterparts inself
. Defaults toTrue
.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.

Return a Python object representation of a Highcharts JavaScript object literal.
- Parameters:
as_str_or_file (
str
) – The JavaScript object literal, represented either as astr
or as a filename which contains the JS object literal.allow_snake_case (
bool
) – IfTrue
, interpretssnake_case
keys as equivalent tocamelCase
keys. Defaults toTrue
._break_loop_on_failure (
bool
) – IfTrue

- 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.
- to_js_literal(filename=None, encoding='utf-8', careful_validation=False) str | None
Return the object represented as a
str
containing the JavaScript object literal.- Parameters:
along the way using the esprima-python library. Defaults to

.Warning
Setting this value to
True
will significantly degrade serialization performance, though it may prove useful for debugging purposes.
- to_json(filename=None, encoding='utf-8', for_export: bool = False)
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 abytes
object depending on the JSON serialization library you are using. For example, if your environment has orjson, the result will be abytes
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'

toNone
instead.- Return type:
numeric or
None
- property center: List[str | int | float | Decimal | EnforcedNullType] | None
The center of the pie chart relative to the plot area.

The id of another series to link to.
Hint
The value can be
':previous'
to link to the previous series. When two series are linked, only the first one appears in the legend. Toggling the visibility of this also toggles the linked series.Note
If the master series uses data sorting and linked series does not have its own sorting definition, the linked series will be sorted in the same order as the master one.
- property marker: Marker | None
Options for the point markers of line-like series.
Properties like
fill_color
,line_color
andline_width
define the visual appearance of the markers. Other series types, like column series, don’t have markers, but have visual options on the series level instead.- Return type:
Marker
orNone

.Note
If
GenericTypeOptions.show_checkbox()
isTrue
, then the checkbox will be checked ifselected

- property size: str | int | None
The diameter of the pie relative to the plot area, expressed as a percentage or pixel value given as an integer.
If
None
, scales the pie to the plot area and gives room for data labels within the plot area.Note
PieOptions.sliced_offset()
is also included in the default size calculation. As a consequence, the size of the pie may vary when points are updated and data labels more around. In that case it is best to set a fixed value, for example"75%"
.
If

When
True
, the (JavaScript)mouseOut
event on a series is not triggered until the mouse moves over another series, or out of the plot area.When
False
, the (JavaScript)mouseOut
event on a series is triggered when the mouse leaves the area around the series’ graph or markers. This also implies the tooltip when not shared.When
False
andPlotOptions.tooltip.shared()
is alsoFalse
, the tooltip will be hidden when moving the mouse between series.Defaults to
True
for line and area type series, but toFalse
for columns, pies, etc.Note
The boost module will force this option because of technical limitations.

0
orNone
to disable.Defaults to
1000
.Note
In boost mode, turbo threshold is forced. Only array of numbers or two dimensional arrays are allowed.
