Enclosing class:

MHG

public class MHG.Axes

extends java.lang.Object

the wrapper class responsible to transform world-coordinates to FIG coordinates at 2400 dpi. We follow the Matlab convention and create a default figure of size 8x6 inches (aspect 4:3). The default transformation maps the axis (xmin,ymin) origin to relative position (0.13, 0.11), that is (0.13*8*2400,0.11*6*2400) or (2496,1584) in absolute FIG coordinates. Similarly, (xmax,ymax) is mapped to (0.13+0.775,0.11+0.815) or (17376, 13320).
