Properties

accessibility → HCSeriesAccessibilityOptionsObject?
(Highstock) Accessibility options for a series.
final
allAreas → dynamic
Not available
final
allowPointSelect → bool?
(Highstock) Allow this series' points to be selected by clicking on the graphic (columns, point markers, pie slices, map areas etc).
final
animation → dynamic
(Highstock) 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 parameter unde
final
animationLimit → num?
(Highstock) For some series, there is a limit that shuts down animation by default when the total number of points in the chart is too high. For example, for a column chart and its derivatives, animation does not run if there is more than 250 points totally. To disable this cap, set animationLimit
final
boostBlending → String?
(Highstock) Sets the color blending in the boost module.
final
boostThreshold → num?
(Highstock) Set the point threshold for when a series should enter boost mode.
final
className → String?
(Highstock) 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?
(Highstock) Disable this option to allow series rendering in the whole plotting area.
final
color → dynamic
(Highstock) The main color of the series. In line type series it applies to the line and the point markers unless otherwise specified. In bar type series it applies to the bars unless a color is specified per point. The default value is pulled from the options.colors array.
final
colorIndex → num?
(Highstock) 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
compareStart → bool?
(Highstock) Defines if comparison should start from the first point within the visible range or should start from the last point before the range.
final
compareToMain → bool?
(Highstock) Whether to compare indicator to the main series values or indicator values.
final
connectNulls → bool?
(Highcharts, Highstock) Whether to connect a graph line across null points, or render a gap between the two points on either side of the null.
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
cropThreshold → num?
(Highcharts, Highstock) When the series contains less points than the crop threshold, all points are drawn, even if the points fall outside the visible plot area at the current zoom. The advantage of drawing all points (including markers and columns), is that animation is performed on updates. On th
final
cumulative → bool?
(Highstock) Cumulative Sum feature replaces points' values with the following formula: sum of all previous points' values + current point's value. Works only for points in a visible range. Adds the cumulativeSum field to each point object that can be accessed e.g. in the tooltip.pointFormat.
final
cumulativeStart → bool?
(Highstock) Defines if cumulation should start from the first point within the visible range or should start from the last point before the range.
final
cursor → String?
(Highstock) 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?
(Highstock) 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
dashStyle → String?
(Highstock) Name of the dash style to use for the graph, or for some series types the outline of each shape.
final
dataGrouping → HCDataGroupingOptionsObject?
(Highstock) Data grouping is the concept of sampling the data values into larger blocks in order to ease readability and increase performance of the JavaScript charts. Highcharts Stock by default applies data grouping when the points become closer than a certain pixel value, determined by the `group
final
dataLabels → dynamic
(Highcharts, Highstock, Highmaps, Gantt) Options for the series data labels, appearing next to each data point.
final
dataMapping → HCDataMappingOptionsObject?
(Highstock) 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 properties of
final
dataParser → dynamic
Not available
final
dataSorting → HCPlotDemaDataSortingOptions?
(Highcharts, Highstock) Options for series data sorting.
final
dataURL → dynamic
Not available
final
description → String?

final
findNearestPointBy → String?
(Highstock) Determines whether the series should look for the nearest point in both dimensions or just the x-dimension when hovering the series. Defaults to 'xy' for scatter series and 'x' for most other series. If the data has duplicate x-values, it is recommended to set this to 'xy' to allow
final

final
gapUnit → String?

final
label → HCSeriesLabelOptionsObject?
(Highcharts, Highstock, Gantt) Series labels are placed as close to the series as possible in a natural way, seeking to avoid other series. The goal of this feature is to make the chart more easily readable, like if a human designer placed the labels in the optimal position.

final
lastVisiblePrice → HCSeriesLastVisiblePriceOptionsObject?

final
name → String?
(Highcharts, Highstock, Highmaps, Gantt) The name of the series as shown in the legend, tooltip etc. If a dataTable and dataMapping are used, the name defaults to the id of the primary data table column. Otherwise, it defaults to "Series {n}", where n is the index of the series, starting at 1.
final
negativeColor → dynamic
(Highstock) The color for the parts of the graph or points that are below the threshold. Note that zones takes precedence over the negative color. Using negativeColor is equivalent to applying a zone with value of 0.
final

(Highcharts, Highstock) The threshold, also called zero level or base level. For line type series this is only used in conjunction with negativeColor.
final
tooltip → HCSeriesTooltipOptionsObject?
(Highstock) A configuration object for the tooltip rendering of each single series. Properties are inherited from tooltip, but only the following properties can be defined on a series level.
final
turboThreshold → num?
(Highcharts, Highstock, Gantt) When a series contains a data array that is longer than this, the Series class looks for data configurations of plain numbers or arrays of numbers. The first and last valid points are checked. If found, the rest of the data is assumed to be the same. This saves expen
