HighchartsTreegraphSeriesDataOptions class

An array of data points for the series. For the treegraph series type, points can be given in the following ways:

  1. The array of arrays, with keys property, which defines how the fields in array should be interpreted data: { id: 'Category1' }, { id: 'Category1', parent: 'Category2', }

An array of data points for the series. For the treegraph series type, points can be given in the following ways:

Properties

accessibility ↔ HighchartsTreegraphSeriesDataAccessibilityOptions?
Accessibility options for a data point.
getter/setter pair
className ↔ String?
An additional, individual class name for the data point's graphic representation. Changes to a point's color will also be reflected in a chart's legend and tooltip.
getter/setter pair
collapseButton ↔ dynamic
Options used for button, which toggles the collapse status of the node.
getter/setter pair
collapsed ↔ bool?
If point's children should be initially hidden
getter/setter pair
color ↔ String?
The color of the point. In heat maps the point color is rarely set explicitly, as we use the color to denote the value. Options for this are set in the colorAxis configuration.
getter/setter pair
colorIndex ↔ double?
A specific color index to use for the point, so its graphic representations are given the class name highcharts-color-{n}. In styled mode this will change the color of the graphic. In non-styled mode, the color is set by the fill attribute, so the change in class name won't have a visual effect by default.
getter/setter pair
colorValue ↔ double?
Serves a purpose only if a colorAxis object is defined in the chart options. This value will decide which color the point gets from the scale of the colorAxis.
getter/setter pair
custom ↔ Map<String, dynamic>?
A reserved subspace to store options and values for customized functionality. Here you can add additional data for your own event callbacks and formatter callbacks.
getter/setter pair
dataLabels ↔ HighchartsTreegraphSeriesDataDataLabelsOptions?
Highcharts Options Widget.
getter/setter pair
description ↔ String?
A description of the point to add to the screen reader information about the point.
getter/setter pair
dragDrop ↔ HighchartsTreegraphSeriesDataDragDropOptions?
Point specific options for the draggable-points module. Overrides options on series.dragDrop.
getter/setter pair
drilldown ↔ String?
The id of a series in the drilldown.series array to use for a drilldown for this point.
getter/setter pair
events ↔ HighchartsTreegraphSeriesDataEventsOptions?
The individual point events.
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
id ↔ String?
An id for the point. This can be used after render time to get a pointer to the point object through chart.get().
getter/setter pair
labelrank ↔ double?
The rank for this point's data label in case of collision. If two data labels are about to overlap, only the one with the highest labelrank will be drawn.
getter/setter pair
marker ↔ HighchartsTreegraphSeriesDataMarkerOptions?
Highcharts Options Widget.
getter/setter pair
name ↔ String?
The name of the point as shown in the legend, tooltip, dataLabels, etc.
getter/setter pair
parent ↔ String?
Only for treemap. Use this option to build a tree structure. The value should be the id of the point which is the parent. If no points has a matching id, or this option is undefined, then the parent will be set to the root.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
selected ↔ bool?
Whether the data point is selected initially.
getter/setter pair
