  • Field Details

    • NONE

      public static final SkyAxisLabeller NONE
      Labeller implementation that does no drawing.
    • LAME

      public static final SkyAxisLabeller LAME
      Basic labeller implementation. Grid lines are drawn OK, but not much effort is made to position axis labels sensibly.
    • EXTERNAL

      public static final SkyAxisLabeller EXTERNAL
      Labeller implementation that draws labels outside the plot bounds.
    • INTERNAL

      public static final SkyAxisLabeller INTERNAL
      Labeller implementation that draws labels inside the plot bounds.
    • EXTSYS

      public static final SkyAxisLabeller EXTSYS
      Labeller implementation like EXTERNAL but with sky system labels.
    • INTSYS

      public static final SkyAxisLabeller INTSYS
      Labeller implementation like INTERNAL but with sky system labels.
    • HYBRID

      public static final SkyAxisLabeller HYBRID
      Labeller implementation that draws labels outside the plot bounds unless they don't appear, in which case it draws them inside. Doesn't necessarily end up looking as sensible as it sounds.
  • Method Details

    • labelCaption

      public static Caption labelCaption(String label)
      Turns a sky grid line label into a Caption. Some manipulation of the text for better LaTeX rendering is done.
      Parameters:
      label - grid line label
      Returns:
      caption object
    • getKnownLabellers

      public static SkyAxisLabeller[] getKnownLabellers()
      Returns a list of the known SkyAxisLabeller instances. The first element is null, which is interpreted as auto mode.
      Returns:
      list of sky axis labellers
    • getAutoLabeller

      public static SkyAxisLabeller getAutoLabeller(boolean skyFillsBounds)
      Returns the axis mode to use if choosing one automatically based on plot characteristics.
      Parameters:
      skyFillsBounds - true if the sky region of the plane fills all or most of the plotting region; false if there are significant non-sky parts
      Returns:
      suitable axis labeller
