  • Enclosing class:
    XYChart<X,Y>


    public static final class XYChart.Data<X,Y>
    extends Object
    A single data item with data for 2 axis charts
    Since:
    JavaFX 2.0
    • Property Detail

      • node

        public final ObjectProperty<Node> nodeProperty
        The node to display for this data item. You can either create your own node and set it on the data item before you add the item to the chart. Otherwise the chart will create a node for you that has the default representation for the chart type. This node will be set as soon as the data is added to the chart. You can then get it to add mouse listeners etc. Charts will do their best to position and size the node appropriately, for example on a Line or Scatter chart this node will be positioned centered on the data values position. For a bar chart this is positioned and resized as the bar for this data item.
