Can't set ticks on the yAxis for the Coordinate Grid Chart

[boesb]

In the prepareYAxis function, the yAxis is hardcoded with the default number of ticks so the number can never be changed.

My solution:

Add new variable:
var _yTicks = DEFAULT_Y_AXIS_TICKS;

Modify prepareYAxis function:
_yAxis = _yAxis.scale(_y).orient("left").ticks(_yTicks);

Add new function:
chart.yTicks = function () {
if (!arguments.length) return _yTicks;
_yTicks = _;
return _chart;
};

Thanks!
