Public Class WholeAxisRange
Properties that return WholeAxisRange instances:
An instance of the WholeAxisRange class can be obtained via the AxisBase.WholeRange property, which defines the whole available range of axis values. The AxisBase.VisualRange property defines which part of the AxisBase.WholeRange should be currently visible on a chart.
So, if the VisualRange is equal to the WholeRange, no scrolling and zooming is applied to chart data. And, if the VisualRange is less than the WholeRange, chart data is zoomed in and scrolled.
