For some series, there is a limit that shuts down initial 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 doesn't run if there is more than 250 points totally. To disable this cap, set
animationLimit
toInfinity
. -
getBorderColor

See Also:
-
setClassName
A class name to apply to the series' graphical elements.
-
getClip
See Also:
-
setClip
Disable this option to allow series rendering in the whole plotting area. Note that clipping should be always enabled when chart.zoomType is set.
Defaults to
true
. -
getColor
See Also:
-
setColor
The main color of the series. In heat maps this color is rarely used, as we mostly use the color to denote the value of each point. Unless options are set in the colorAxis, the default value is pulled from the options.colors array.
Defaults to: null
-
getColorByPoint
See Also:
-
setColorByPoint
When using automatic point colors pulled from the
options.colors
collection, this option determines whether the chart should receive one color per series or one color per point.Defaults to: false
-
getColorIndex
See Also:
-
setColorIndex
Styled mode only. A specific color index to use for the series, so its graphic representations are given the class name
highcharts-color-{n}
. -
getColorKey
See Also:
-
setColorKey
Determines what data value should be used to calculate point color if
colorAxis
is used. Requires to setmin
andmax
if some custom point property is used or if approximation for data grouping is set to'sum'
.Defaults to
value
. -
getColors
See Also:
-
setColors
A series specific or series type specific color set to apply instead of the global colors when colorByPoint is true.
-
addColor
Adds color to the colors array
Parameters:
color
- to addSee Also:
-
removeColor
Removes first occurrence of color in colors array
Parameters:
color
- to removeSee Also:
-
getColsize
See Also:
-
setColsize
The column size - how many X axis units each column in the heatmap should span.
Defaults to: 1
-
getCrisp
See Also:
-
setCrisp
When true, each 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, setting
crisp
tofalse
may look better, even though each column is rendered blurry.Defaults to: true
-
getCropThreshold
See Also:
-
setCropThreshold
When the series contains less points than the crop threshold, all points are drawn, event 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 the other hand, when the series contains more points than the crop threshold, the series data is cropped to only contain points that fall within the plot area. The advantage of cropping away invisible points is to increase performance on large series. .
Defaults to: 50
-
getCursor
See Also:
-
setCursor
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.
-
getDataLabels
See Also:
-
setDataLabels
Options for the series data labels, appearing next to each data point.
In styled mode, the data labels can be styled wtih the
.highcharts-data-label-box

Defaults to: true
-
getExposeElementToA11y
See Also:
-
setExposeElementToA11y
By default, series are exposed to screen readers as regions. By enabling this option, the series element itself will be exposed in the same way as the data points. This is useful if the series is not used as a grouping entity in the chart, but you still want to attach a description to the series.
Requires the Accessibility module.
Defaults to: undefined
-
getFindNearestPointBy
See Also:

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 hovering over all points.Applies only to series types using nearest neighbor search (not direct hover) for tooltip.
-

See Also:
-
setStickyTracking
Sticky tracking of mouse events. When true, the
mouseOut
event on a series isn't triggered until the mouse moves over another series, or out of the plot area. When false, themouseOut
event on a series is triggered when the mouse leaves the area around the series' graph or markers. This also implies the tooltip. WhenstickyTracking
is false andtooltip.shared
is false, the tooltip will be hidden when moving the mouse between series. Defaults to true for line and area type series, but to false for columns, pies etc.Defaults to: true

setTurboThreshold
When a series contains a data array that is longer than this, only one dimensional arrays of numbers, or two dimensional arrays with x and y values are allowed. Also, only the first point is tested, and the rest are assumed to be the same format. This saves expensive data checking and indexing in long series. Set it to
0
disable.Defaults to: 1000

option (view live demo). -
