      When enabled the user can click on a point which is a parent and zoom in on its children.

      Defaults to: false

    • getAllowPointSelect

      Defaults to: false

    • getAlternateStartingDirection

      public Boolean getAlternateStartingDirection()
      See Also:

    • setAlternateStartingDirection

      public void setAlternateStartingDirection(Boolean alternateStartingDirection)
      Enabling this option will make the treemap alternate the drawing direction between vertical and horizontal. The next levels starting direction will always be the opposite of the previous.

      Defaults to: false

    • getAnimation

      public Boolean getAnimation()
      See Also:

    • setAnimation

      public void setAnimation(Boolean animation)
      Enable or disable the initial animation when a series is displayed. Please note that this option only applies to the initial animation of the series itself. For other animations, see ChartModel.setAnimation(Boolean)

    • getAnimationLimit

      public Number getAnimationLimit()
      See Also:

    • setAnimationLimit

      public void setAnimationLimit(Number animationLimit)
      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 to Infinity.

    • getBorderColor

      public Color getBorderColor()
      See Also:

    • setBorderColor

      public void setBorderColor(Color borderColor)

      See Also:

    • setBorderWidth

      public void setBorderWidth(Number borderWidth)

      See Also:

    • setClassName

      public void setClassName(String className)
      A class name to apply to the series' graphical elements.

    • getColor

      public Color getColor()
      See Also:

    • setColor

      public void setColor(Color color)
      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

      public Boolean getColorByPoint()
      See Also:

    • setColorByPoint

      public void setColorByPoint(Boolean colorByPoint)

      Defaults to: false

    • getColorIndex

      public Number getColorIndex()
      See Also:

    • setColorIndex

      public void setColorIndex(Number colorIndex)
      Styled mode only. A specific color index to use for the series, so its graphic representations are given the class name highcharts-color-{n}.

    • getColors

      public Color[] getColors()
      See Also:

    • setColors

      public void setColors(Color... colors)
      A series specific or series type specific color set to apply instead of the global colors when colorByPoint is true.

    • addColor

      public void addColor(Color color)
      Adds color to the colors array
      Parameters:
      color - to add
      See Also:

    • removeColor

      public void removeColor(Color color)
      Removes first occurrence of color in colors array
      Parameters:
      color - to remove
      See Also:

    • getCrisp

      public Boolean getCrisp()
      See Also:

    • setCrisp

      public void setCrisp(Boolean crisp)
      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 to false may look better, even though each column is rendered blurry.

      Defaults to: true

    • getCropThreshold

      public Number getCropThreshold()
      See Also:

    • setCropThreshold

      public void setCropThreshold(Number cropThreshold)
      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: 300

    • getCursor

      public Cursor getCursor()
      See Also:

    • setCursor

      public void setCursor(Cursor cursor)
      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

      public DataLabels getDataLabels()
      See Also:

    • setDataLabels

      public void setDataLabels(DataLabels dataLabels)

      A description of the series to add to the screen reader information about the series.

      Defaults to: undefined

    • getEnableMouseTracking

      public Boolean getEnableMouseTracking()
      See Also:

    • setEnableMouseTracking

      public void setEnableMouseTracking(Boolean enableMouseTracking)
      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.

      Defaults to: true

    • getExposeElementToA11y

      public Boolean getExposeElementToA11y()
      See Also:

    • setExposeElementToA11y

      public void setExposeElementToA11y(Boolean exposeElementToA11y)

      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

      public Dimension getFindNearestPointBy()
      See Also:

    • setFindNearestPointBy

      public void setFindNearestPointBy(Dimension findNearestPointBy)

      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.

      Defaults to: false

    • getIgnoreHiddenPoint

      public Boolean getIgnoreHiddenPoint()
      See Also:

      See Also:

    • setKeys

      public void setKeys(String... keys)
      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.

      See Also:

    • setStickyTracking

      public void setStickyTracking(Boolean stickyTracking)
      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, the mouseOut event on a series is triggered when the mouse leaves the area around the series' graph or markers. This also implies the tooltip. When stickyTracking is false and tooltip.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.

      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
