Namespace Detail
JXG.Options
Options Namespace These are the default options of the board and of all geometry elements.
Field Detail
{Object} layer
Default ordering of the layers. The numbering starts from 0 and the highest layer number is numlayers-1. The default values are

    JXG.Options.layer: {
      numlayers: 20, // only important in SVG
      text: 9,
      point: 9,
      glider: 9,
      arc: 8,
      line: 7,
      circle: 6,
      curve: 5,
      turtle: 5,
      polygon: 3,
      sector: 3,
      angle: 3,
      integral: 3,
      axis: 2,
      ticks: 2,
      grid: 1,
      image: 0,
      trace: 0
    }

{Object} navbar
Options that are used by the navigation bar. Default values are

    JXG.Option.navbar: {
      strokeColor: '#333333',
      fillColor: 'transparent',
      highlightFillColor: '#aaaaaa',
      padding: '2px',
      position: 'absolute',
      fontSize: '14px',
      cursor: 'pointer',
      zIndex: '100',
      right: '5px',
      bottom: '5px'
    },

These settings are overruled by the CSS class 'JXG_navigation'.

{Object} precision
Precision options, defining how close a pointer device (mouse, finger, pen) has to be to an object such that the object is highlighted or can be dragged. These values are board-wide and can be overwritten for individual elements by changing their precision attribute. The default values are

    JXG.Options.precision: {
      touch: 30,
      touchMax: 100,
      mouse: 4,
      pen: 4,
      epsilon: 0.0001,
      hasPoint: 4
    }

See:
  JXG.GeometryElement#precision

{Object} shortcuts
Abbreviations of attributes. Setting the shortcut means setting abbreviated properties to the same value. It is used in JXG.GeometryElement#setAttribute and in the constructor JXG.GeometryElement. Attention: In Options.js abbreviations are not allowed.
