   * @class Ext.chart.axis.Numeric
   * @extends Ext.chart.axis.Axis
   *
   * An axis to handle numeric values. This axis is used for quantitative data as
   * opposed to the category axis. You can set minimum and maximum values to the
   * axis so that the values are bound to that. If no values are set, then the
   * scale will auto-adjust to the values.
   *
   *     @example
   *     Ext.create({
   *        xtype: 'cartesian', 
   *        renderTo: document.body,
   *        width: 600,
   *        height: 400,
   *        store: {
   *            fields: ['name', 'data1', 'data2', 'data3'],
   *            data: [{
   *                'name': 1,
   *                'data1': 10,
   *                'data2': 12,
   *                'data3': 14
   *            }, {
   *                'name': 2,
   *                'data1': 7,
   *                'data2': 8,
   *                'data3': 16
   *            }, {
   *                'name': 3,
   *                'data1': 5,
   *                'data2': 2,
   *                'data3': 14
   *            }, {
   *                'name': 4,
   *                'data1': 2,
   *                'data2': 14,
   *                'data3': 6
   *            }, {
   *                'name': 5,
   *                'data1': 27,
   *                'data2': 38,
   *                'data3': 36
   *            }]
   *        },
   *        axes: {
   *            type: 'numeric',
   *            position: 'left',
   *            minimum: 0,
   *            fields: ['data1', 'data2', 'data3'],
   *            title: 'Sample Values',
   *            grid: {
   *                odd: {
   *                    opacity: 1,
   *                    fill: '#F2F2F2',
   *                    stroke: '#DDD',
   *                    'lineWidth': 1
   *                }
   *            }
   *        },
   *        series: {
   *            type: 'area',
   *            subStyle: {
   *                fill: ['#0A3F50', '#30BDA7', '#96D4C6']
   *            },
   *            xField: 'name',
   *            yField: ['data1', 'data2', 'data3']
   *        }
   *     });
   *
   * In this example we create an axis of Numeric type. We set a minimum value so that
   * even if all series have values greater than zero, the grid starts at zero. We bind
   * the axis onto the left part of the surface by setting _position_ to _left_.
   * We bind three different store fields to this axis by setting _fields_ to an array.
   * We set the title of the axis to _Number of Hits_ by using the _title_ property.
   * We use a _grid_ configuration to set odd background rows to a certain style and even rows
   * to be transparent/ignored.
