Properties

accessibility → HCSeriesAccessibilityOptionsObject?
(Highcharts, Highmaps) Accessibility options for a series.
final
allowPointSelect → bool?
(Highcharts, Highmaps) Allow this series' points to be selected by clicking on the graphic (columns, point markers, pie slices, map areas etc).
final
animation → dynamic
(Highcharts, Highmaps) Enable or disable the initial animation when a series is displayed. The animation can also be set as a configuration object. Please note that this option only applies to the initial animation of the series itself. For other animations, see chart.animation and the animation par
final
borderColor → dynamic
(Highcharts, Highmaps) The color of the border surrounding each slice. When null, the border takes the same color as the slice fill. This can be used together with a borderWidth to fill drawing gaps created by antialiasing artifacts in border-less pies.
final
borderRadius → dynamic
(Highcharts, Highmaps) The corner radius of the border surrounding each slice. A number signifies pixels. A percentage string, like for example 50%, signifies a size relative to the radius and the inner radius.
final
borderWidth → num?
(Highcharts, Highmaps) The width of the border surrounding each slice.
final
center → dynamic
(Highcharts, Highmaps) The center of the pie chart relative to the plot area. Can be percentages or pixel values. The default behavior (as of 3.0) is to center the pie so that all slices and data labels are within the plot area. As a consequence, the pie may actually jump around in a chart with dyna
final
className → String?
(Highcharts, Highmaps) An additional class name to apply to the series' graphical elements. This option does not replace default class names of the graphical element. Changes to the series' color will also be reflected in a chart's legend and tooltip.
final
clip → bool?
(Highcharts) Disable this option to allow series rendering in the whole plotting area.
final
color → dynamic
(Highcharts, Highmaps) The color of the pie series. A pie series is represented as an empty circle if the total sum of its values is 0. Use this property to define the color of its border.
final
colorAxis → dynamic
(Highcharts, Highstock, Highmaps) When using dual or multiple color axes, this number defines which colorAxis the particular series is connected to. It refers to either the axis id or the index of the axis in the colorAxis array, with 0 being the first. Set this option to false to prevent a series f
final
colorIndex → num?
(Highcharts, Highmaps) Styled mode only. A specific color index to use for the series, so its graphic representations are given the class name highcharts-color-{n}.
final
colorKey → String?
(Highcharts, Highstock, Highmaps) Determines what data value should be used to calculate point color if colorAxis is used. Requires to set min and max if some custom point property is used or if approximation for data grouping is set to 'sum'.
final
colors → List?
(Highcharts, Highmaps) A series specific or series type specific color set to use instead of the global colors.
final
crisp → bool?
(Highcharts, Highstock, Gantt) When true, each point or column edge is rounded to its nearest pixel in order to render sharp on screen. In some cases, when there are a lot of densely packed columns, this leads to visible difference in column widths or distance between columns. In these cases, settin
final
cursor → String?
(Highcharts, Highmaps) You can set the cursor to "pointer" if you have click events attached to the series, to signal to the user that the points and lines can be clicked.
final
custom → HCDictionary?
(Highcharts, Highmaps) 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.
final
dataLabels → dynamic
(Highcharts, Highstock, Highmaps, Gantt) Options for the series data labels, appearing next to each data point.
final
dataMapping → HCDataMappingOptionsObject?
(Highcharts, Highmaps) The mapping between the data table and the series data points. This is used in conjunction with the dataTable option (on chart or series level) to map columns from the data table to the properties of the data points. The keys of the dataMapping object correspond to the pro
final
depth → num?
(Highcharts) The thickness of a 3D pie.
final
description → String?
(Highcharts, Highmaps) Deprecated. Use plotOptions.series.accessibility.description instead.
final
enableMouseTracking → bool?
(Highcharts, Highmaps) Enable or disable the mouse tracking for a specific series. This includes point tooltips and click events on graphs and points. For large datasets it improves performance.
final
endAngle → num?
(Highcharts, Highmaps) The end angle of the pie in degrees where 0 is top and 90 is right. Defaults to startAngle plus 360.
final
events → HCSeriesEventsOptionsObject?
(Highcharts, Highmaps) General event handlers for the series items. These event hooks can also be attached to the series at run time using the Highcharts.addEvent function.
final
fillColor → dynamic
(Highcharts, Highmaps) If the total sum of the pie's values is 0, the series is represented as an empty circle . The fillColor option defines the color of that circle. Use pie.borderWidth to set the border thickness.
final
gapSize → num?
(Highcharts, Highstock) Defines when to display a gap in the graph, together with the gapUnit option.
final
gapUnit → String?
(Highcharts, Highstock) Together with gapSize, this option defines where to draw gaps in the graph.
final
hashCode → int
The hash code for this object.
no setterinherited
ignoreHiddenPoint → bool?
(Highcharts, Highmaps) Equivalent to chart.ignoreHiddenSeries, this option tells whether the series shall be redrawn as if the hidden point were null.
final
inactiveOtherPoints → bool?
(Highcharts, Highmaps) Highlight only the hovered point and fade the remaining points.
final
includeInDataExport → bool?
(Highcharts, Highmaps) When set to false will prevent the series data from being included in any form of data export.
final
innerSize → dynamic
(Highcharts, Highmaps) The size of the inner diameter for the pie. A size greater than 0 renders a donut chart. Can be a percentage or pixel value. Percentages are relative to the pie size. Pixel values are given as integers. Setting overridden by thickness.
final
joinBy → dynamic
(Highmaps) What property to join the mapData to the value data. For example, if joinBy is "code", the mapData items with a specific code is merged into the data with the same code. For maps loaded from GeoJSON, the keys may be held in each point's properties object.
final
keys → List<String>?
(Highcharts, Highmaps) An array specifying which option maps to which key in the data point array. This makes it convenient to work with unstructured data arrays from different sources.
final
legendSymbol → String?
(Highcharts, Highmaps) What type of legend symbol to render for this series. Can be one of areaMarker, lineMarker or rectangle.
final
legendSymbolColor → dynamic
(Highcharts, Highstock, Highmaps) Defines the color of the legend symbol for this series. Defaults to undefined, in which case the series color is used. Does not work with styled mode.
final
linecap → String?
(Highcharts, Highmaps) The line cap used for line ends and line joins on the graph.
final
minSize → dynamic

final
nullInteraction → bool?
(Highcharts, Highstock) Whether or not data-points with the value of null should be interactive. When this is set to true, tooltips may highlight these points, and this option also enables keyboard navigation for such points. Format options for such points include nullFormat and `nullFormatter

final
relativeXValue → bool?
(Highcharts, Highstock) When true, X values in the data set are relative to the current pointStart, pointInterval and pointIntervalUnit settings. This allows compression of the data for datasets with irregular X values.
final
runtimeType → Type
A representation of the runtime type of the object.
