Class PlotOptionsTreemap

  • All Implemented Interfaces:

    Serializable

    public class PlotOptionsTreemap
extends AbstractPlotOptions

    The size of the point shape is determined by its value relative to its siblings values. Requires the module heatmap.js as well, if functionality such as the colorAxis is to be used.

    • Method Detail

      • setAllowDrillToNode

        public void setAllowDrillToNode​(Boolean allowDrillToNode)

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

        Defaults to: false

      • 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

      • 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

      • 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)

      • 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.

      • setBorderColor

        public void setBorderColor​(Color borderColor)

        The color of the border surrounding each tree map item.

        Defaults to: #e6e6e6

      • setBorderWidth

        public void setBorderWidth​(Number borderWidth)

        The width of the border surrounding each column or bar.

        In styled mode, the stroke width can be set with the .highcharts-point rule.

        Defaults to: 1

      • setClassName

        public void setClassName​(String className)

        A class name to apply to the series' graphical elements.

      • 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

      • setColorByPoint

        public void setColorByPoint​(Boolean colorByPoint)

        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

      • 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}.

      • 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:

        setColors(Color...)

      • removeColor

        public void removeColor​(Color color)

        Removes first occurrence of color in colors array

        Parameters:

        color - to remove

        See Also:

        setColors(Color...)

      • 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

      • 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

      • 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.

      • setDataLabels

        public void setDataLabels​(DataLabels dataLabels)

      • 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

      • 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

      • 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

      • 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.

      • setGetExtremesFromAll

        public void setGetExtremesFromAll​(Boolean getExtremesFromAll)

        Whether to use the Y extremes of the total chart width or only the zoomed area when zooming in on parts of the X axis. By default, the Y axis adjusts to the min and max of the visible data. Cartesian series only.

        Defaults to: false

      • setIgnoreHiddenPoint

        public void setIgnoreHiddenPoint​(Boolean ignoreHiddenPoint)

        Whether to ignore hidden points when the layout algorithm runs. If false, hidden points will leave open spaces.

        Defaults to: true

      • setInteractByLeaf

        public void setInteractByLeaf​(Boolean interactByLeaf)

        This option decides if the user can interact with the parent nodes or just the leaf nodes. When this option is undefined, it will be true by default. However when allowDrillToNode is true, then it will be false by default.

      • 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.

      • setLayoutStartingDirection

        public void setLayoutStartingDirection​(TreeMapLayoutStartingDirection layoutStartingDirection)

        Defines which direction the layout algorithm will start drawing. Possible values are "vertical" and "horizontal".

        Defaults to: vertical

      • setLevelIsConstant

        public void setLevelIsConstant​(Boolean levelIsConstant)

        Used together with the levels and allowDrillToNode options. When set to false the first level visible when drilling is considered to be level one. Otherwise the level will be the same as the tree structure.

        Defaults to: true

      • setLevels

        public void setLevels​(Level... levels)

        Set options on specific levels. Takes precedence over series options, but not point options.

        The id of another series to link to. Additionally, the value can be ":previous" to link to the previous series. When two series are linked, only the first one appears in the legend. Toggling the visibility of this also toggles the linked series.

      • setMaxPointWidth

        public void setMaxPointWidth​(Number maxPointWidth)

        The maximum allowed pixel width for a column, translated to the height of a bar in a bar chart. This prevents the columns from becoming too wide when there is a small number of points in the chart.

        Defaults to: null

      • setOpacity

        public void setOpacity​(Number opacity)

        The opacity of a point in treemap. When a point has children, the visibility of the children is determined by the opacity.

        Defaults to: 0.15

      • setShowCheckbox

        public void setShowCheckbox​(Boolean showCheckbox)

        If true, a checkbox is displayed next to the legend item to allow selecting the series. The state of the checkbox is determined by the selected option.

        Defaults to: false

      • setShowInLegend

        public void setShowInLegend​(Boolean showInLegend)

        Whether to display this series type or specific series item in the legend.

        Defaults to: false

      • setSkipKeyboardNavigation

        public void setSkipKeyboardNavigation​(Boolean skipKeyboardNavigation)

        If set to True, the accessibility module will skip past the points in this series for keyboard navigation.

      • setSortIndex

        public void setSortIndex​(Number sortIndex)

        The sort index of the point inside the treemap level.

      • setStates

        public void setStates​(States states)

        A wrapper object for all the series options in specific states.

      • 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.

        Defaults to: true

      • setTurboThreshold

        public void setTurboThreshold​(Number turboThreshold)

        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

      • setVisible

        public void setVisible​(Boolean visible)

        Set the initial visibility of the series.
