//  File:		SubAxis.cs
//
//  Namespace:	DataVisualization.Charting
//
//	Classes:	SubAxis, SubAxisCollection
//
//  Purpose:	Each chart area contains four main axes PrimaryX, 
//              PrimaryY, SecondaryX and SecondaryY which are usually 
//              positioned on each side of the plotting area. Most of 
//              the charts use only two axes; X and Y, but for some 
//              charts even 4 axes is not sufficient. Sub-axes were 
//              introduced to provide unlimited number of axes in 
//              the chart.
//  
//              Each main axis has a collection of SubAxis which is 
//              empty by default. By adding SubAxis into this collection 
//              user can add unlimited number of sub-axis which will 
//              be positioned next to the main axis.
//
//              Each of the SubAxis have a unique name. To associate 
//              data series with a sub axis YSubAxisName and XSubAxisName 
//              properties of the Series should be used.
//
