    See Also:
    
    setColor(Color)
  - 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(Boolean)
  - setColorByPoint

```
public Number getColorIndex()
```
    See Also:
    
    setColorIndex(Number)
  - 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}.

    Defaults to value.
  - getColors
```
public Color[] getColors()
```
    See Also:
    
    setColors(Color...)

  - addColor
```
public void addColor(Color color)
```
    Adds color to the colors array
    
    Parameters:
    
    color - to add
    
    See Also:
    
    setColors(Color...)
  - removeColor
```
public void removeColor(Color color)
```
    Removes first occurrence of color in colors array
    
    Parameters:
    
    color - to remove
    
    See Also:
    
    setColors(Color...)
  - getColsize
```
public Number getColsize()
```
    See Also:
    
    setColsize(Number)
  - 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(Boolean)
  - 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(Number)
  - 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(Cursor)
  - 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(DataLabels)
  - 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(String)
  - setDescription
```

```
public Boolean getEnableMouseTracking()
```
    See Also:
    
    setEnableMouseTracking(Boolean)
  - 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.

  - 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(Dimension)
  - 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.

```
public Boolean getGetExtremesFromAll()
```

    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.
