Element Detail
Ticks
Ticks are markers on straight line elements or curves.
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "ticks".

Possible parent array combinations are:
{JXG.Line|JXG.Curve} line

The parents consist of the line or curve the ticks are going to be attached to.


{Number|Array} distance

Number defining the distance between two major ticks or an array defining static ticks. In case a number is specified, the ticks are equidistant, in case of an array, a fixed number of static ticks is created at user-supplied positions. Alternatively, the distance can be specified with the attribute "ticksDistance". For arbitrary lines (and not axes) a "zero coordinate" is determined which defines where the first tick is positioned. This zero coordinate can be altered with the attribute "anchor". Possible values are "left", "middle", "right" or a number. The default value is "left".


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create an axis providing two coordinate pairs.
  var p1 = board.create('point', [0, 3]);
  var p2 = board.create('point', [1, 3]);
  var l1 = board.create('line', [p1, p2]);
  var t = board.create('ticks', [l1], {ticksDistance: 2});

				
                
Attribute Detail
{String} anchor
Determine the position of the tick with value 0. 'left' means point1 of the line, 'right' means point2, and 'middle' is equivalent to the midpoint of the defining points. This attribute is ignored if the parent line is of type axis.
Defined in: options.js.
Default Value:
'left'

{Boolean} beautifulScientificTickLabels
Format tick labels that were going to have scientific notation like 5.00e+6 to look like 5•10⁶.
Defined in: options.js.
var board = JXG.JSXGraph.initBoard("jxgbox", {
    boundingbox: [-500000, 500000, 500000, -500000],
    axis: true,
    defaultAxes: {
        x: {
            scalable: true,
            ticks: {
                beautifulScientificTickLabels: true
          },
        },
        y: {
            scalable: true,
            ticks: {
                beautifulScientificTickLabels: true
          },
        }
    },
});


					
					

						
						
						
						
							
Default Value:
false

{Number} digits
If a label exceeds Ticks#maxLabelLength this determines the number of digits used to shorten the tick label.
Defined in: options.js.
See:
Ticks#maxLabelLength
Default Value:
3

{Boolean} drawLabels
Draw labels yes/no
Defined in: options.js.
Default Value:
false

{Boolean} drawZero
Draw the zero tick, that lies at line.point1?
Defined in: options.js.
Default Value:
false

{function} generateLabelText
A function that expects two JXG.Coords, the first one representing the coordinates of the tick that is to be labeled, the second one the coordinates of the center (the tick with position 0). The third parameter is a null, number or a string. In the latter two cases, this value is taken. Returns a string.
Defined in: options.js.

{function} generateLabelValue
A function that expects two JXG.Coords, the first one representing the coordinates of the tick that is to be labeled, the second one the coordinates of the center (the tick with position 0).
Defined in: options.js.
Deprecated:
Use JGX.Options@generateLabelText

{Boolean} ignoreInfiniteTickEndings
If true, ignore the tick endings attribute for infinite (full height) ticks. This affects major and minor ticks.
Defined in: options.js.
See:
Ticks#tickEndings
Ticks#majorTickEndings
Default Value:
true

{Boolean} includeBoundaries
Whether line boundaries should be counted or not in the lower and upper bounds when creating ticks.
Defined in: options.js.
Default Value:
false

{Boolean} insertTicks
If the distance between two ticks is too big we could insert new ticks. If insertTicks is true, we'll do so, otherwise we leave the distance as is. This option is ignored if equidistant is false. In the example below the distance between two ticks is given as 1 but because insertTicks is set to true many ticks will be omitted in the rendering process to keep the display clear.
Defined in: options.js.
// Create an axis providing two coord pairs.
  var p1 = board.create('point', [0, 0]);
  var p2 = board.create('point', [50, 25]);
  var l1 = board.create('line', [p1, p2]);
  var t = board.create('ticks', [l1, 1], {
     insertTicks: true,
     majorHeight: -1,
     label: {
         offset: [4, -9]
     },
     drawLabels: true
 });
