Class Detail
Grid()
A grid is a set of vertical and horizontal lines to support the user with element placement. This method
draws such a grid on the given board. It uses options given in JXG.Options#grid. This method does not
take any parent elements. It is usually instantiated on the board's creation via the attribute grid set
to true.
grid = board.create('grid', []);
- Throws:
- {Error}
- If the element cannot be constructed with the given parent objects an exception is thrown.
