Element Detail
Chart
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "chart".

Possible parent array combinations are:
{Array} x

Array of x-coordinates (default case, see below for alternatives)


{Array} y

Array of y-coordinates (default case, see below for alternatives)

The parent array may be of one of the following forms:

  1. Parents array looks like [number, number, number, ...]. It is interpreted as array of y-coordinates. The x coordinates are automatically set to [1, 2, ...]
  2. Parents array looks like [[number, number, number, ...]]. The content is interpreted as array of y-coordinates. The x coordinates are automatically set to [1, 2, ...]x coordinates are automatically set to [1, 2, ...] Default case: [[x0,x1,x2,...],[y1,y2,y3,...]]
The attribute value for the key 'chartStyle' determines the type(s) of the chart. 'chartStyle' is a comma separated list of strings of the possible chart types 'bar', 'fit', 'line', 'pie', 'point', 'radar', 'spline'.


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
