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

Possible parent array combinations are:

The two arrays give the initial position where the tape measure is drawn on the board.


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create a tape measure
var p1 = board.create('point', [0,0]);
var p2 = board.create('point', [1,1]);
var p3 = board.create('point', [3,1]);
var tape = board.create('tapemeasure', [[1, 2], [4, 2]], {name:'dist'});
