style with the opposite color, to further increase the contrast. This can be overridden by setting thetext-outline
style tonone
in theDataLabel.style()
setting.
- property crop: bool | None

- property null_formatter: CallbackFunction | None
JavaScript callback function to format the text of the data label for visible null points.
Note
Works analogously to

- Return type:
CallbackFunction
orNone

Configuration on how to handle a data label that overflows outside of the plot area. Defaults to

To display data labels outside the plot area, set
overflow
to'allow'
andDataLabel.crop()
toFalse

.Accepts:
'rect'
'square'
'circle'
'diamond'
'triangle'
'callout'
- 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"
. WhenDataLabel.use_html()
isTrue
, thetextOutline
will not be picked up. In this, case, the same effect can be acheived through thetext-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.
- 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.
- property use_html: bool | None

, will use SVG or WebGL as applicable.Defaults to
False
.
- 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'
- property x: int | float | Decimal | None
The x position offset of the label relative to the point. Defaults to
0
