    • getAllowPointSelect

      public Boolean getAllowPointSelect()
      See Also:

    • setAllowPointSelect

      public void setAllowPointSelect(Boolean allowPointSelect)
      Allow this series' points to be selected by clicking on the markers, bars or pie slices.

      Defaults to: false

    • getAnimation

      public Boolean getAnimation()
      See Also:

    • setAnimation

      public void setAnimation(Boolean animation)

      public Number getAnimationLimit()
      See Also:

      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

      public Number getColorIndex()
      See Also:

    • setColorIndex

      public void setColorIndex(Number colorIndex)

      public String getColorKey()
      See Also:

    • setColorKey

      public void setColorKey(String colorKey)
      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'.

      Defaults to value.

    • 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:

    • getColsize

      public Number getColsize()
      See Also:

    • setColsize

      public void setColsize(Number colsize)
      The column size - how many X axis units each column in the heatmap should span.

      Defaults to: 1

    • 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: 50

    • getCursor

      public Cursor getCursor()
      See Also:

    • setCursor

      public void setCursor(Cursor cursor)

    • getDataLabels

      public DataLabels getDataLabels()
      See Also:

    • setDataLabels

      public void setDataLabels(DataLabels dataLabels)

      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 and .highcharts-data-label class names (see example).

    • getDescription

      public String getDescription()
      See Also:

    • setDescription

      public void setDescription(String description)

      Requires Accessibility module

      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

      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.

      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.
