    • animate

      protected void animate​(Animation animation)
      Play the given animation on every frame of the animation the chart will be relayed out until the animation finishes. So to add a animation to a chart, create a animation on data model, during layoutChartContent() map data model to nodes then call this method with the animation.
      Parameters:
      animation - The animation to play

    • requestChartLayout

      This is used to check if any given animation should run. It returns true if animation is enabled and the node is visible and in a scene.
      Returns:
      true if animation is enabled and the node is visible and in a scene

    • layoutChartChildren

      Called to update and layout the chart children available from getChartChildren()
      Parameters:
      top - The top offset from the origin to account for any padding on the chart content
      left - The left offset from the origin to account for any padding on the chart content

    • computeMinHeight

      protected double computeMinHeight​(double width)
      Charts are sized outside in, user tells chart how much space it has and chart draws inside that. So minimum height is a constant 150.

      computeMinHeight in class Region
      Parameters:
      width - the width that should be used if min height depends on it
      Returns:
      the computed minimum height for this region

    • computeMinWidth

      protected double computeMinWidth​(double height)
      Charts are sized outside in, user tells chart how much space it has and chart draws inside that. So minimum width is a constant 200.
      Overrides:
      computeMinWidth in class Region
      Parameters:
      height - the height that should be used if min width depends on it
      Returns:
      the computed minimum width of this region

    • computePrefWidth

      protected double computePrefWidth​(double height)
      Charts are sized outside in, user tells chart how much space it has and chart draws inside that. So preferred width is a constant 500.
      Overrides:
      computePrefWidth in class Region
      Parameters:
      height - the height that should be used if preferred width depends on it
      Returns:
      the computed preferred width for this region

    • computePrefHeight

      protected double computePrefHeight​(double width)
      Charts are sized outside in, user tells chart how much space it has and chart draws inside that. So preferred height is a constant 400.
      Overrides:
      computePrefHeight in class Region
      Parameters:
      width - the width that should be used if preferred height depends on it
      Returns:
      the computed preferred height for this region

    • getClassCssMetaData

      public static List<CssMetaData<? extends Styleable,​?>> getClassCssMetaData()
      Returns:
      The CssMetaData associated with this class, which may include the CssMetaData of its superclasses.
      Since:
      JavaFX 8.0

    • getCssMetaData

      public List<CssMetaData<? extends Styleable,​?>> getCssMetaData()
      This method should delegate to Node.getClassCssMetaData() so that a Node's CssMetaData can be accessed without the need for reflection.
      Specified by:
      getCssMetaData in interface Styleable
      Overrides:
      getCssMetaData in class Region
      Returns:
      The CssMetaData associated with this node, which may include the CssMetaData of its superclasses.
