Class figPac.fAxes 

java.lang.Object
   |
   +----figPac.fAxes
public class fAxes
extends Object
implements fElement
Draws the x and y axes, puts ticks on the axes, gives the coordinate values corresponding to the ticks and puts labels on the axes. Optionally, the clip path is also set to a rectangle through the ends of the coordinate axes (not yet implemented). Optionally, for the main Figure only (not fSubFigures) and only when the coordinate map is invertible, the limits for the x and y axes are chosen automatically, with xmin being the larger of the x coordinates of the two left hand corners of the Figure and so on. The spacing and positioning of the ticks is chosen automatically to give between 4 and 20 ticks on each axis and to have the coordinate values increase by 1, 2 or 5 in the last decimal place displayed. Axis labels that will overlap the axes or neighbouring coordinate values are skipped. As well the figure margins are adjusted so that the axis data is visible on the screen. When the figure is to be inserted in a TeX file and is to contain TeX labels (precisely, if there exists and entry in the table env with the name "outputLblFile" and value "true") the figure margins are not adjusted and no labels are output. This class does not work well when the coordinate axes are not parallel to the sides of the figure.
