Classpublic class BoundedValue
InheritanceBoundedValue Inheritance Object

A bounded value is used to represent a datapoint that a chart element intends to render on screen. ChartElements report BoundedValues describing their data to an Axis object that the axis computes autogenerated ranges. A BoundedValue encapsulates both the value of the datapoint in a particualr dimension, as well as a margin, in pixels, that a ChartElement needs above or below the value in order to render it. Plots on a plot chart, for example, report their data with margins to accomodate the size of the plots. A column chart might report a margin in the Y axis to accomodate a label rendered above the chart.
