public class NFAxisMap

extends NFBaseClass

implements NFCDLGenerator

The Axis map object is used to identify how each dimension of a data element is translated into screen coordinates. For example consider the X/Y coordinate (10,15). Using the NFAxisMap object, we can instruct the rendering engine that the X coordinate should be mapped to the top axis scale, and the Y axis should be mapped to the left axis scale. If top axis scale ranges from 0 - 10 and the left axis scale ranges from 0 - 100, the point will be drawn at the far right side of the chart, about 15% of the way up from the bottom axis.

The NFAxis Map object also provides developers the ability to map to multiple axes on any given side by specifying the axis and the index to the axis on a given side (from 1 - N axes per side).

Some implementations of this object also allow the use of PIXEL or PERCENT. PIXEL indicates that the dimension value should be mapped using pixels relative to the upper left corner of the drawing area. PERCENTAGE means that the dimension value should be mapped as a percentage of the overall width/height of the chart.
