[4.0.2] Y-axis not generated if all values are 0

[mailisa]

Possible bug: When creating a chart (stacked column is what I was using), if all the y values for a particular y have a 0 value, the y-xis is not rendered.

Also noticed this bug in FireBug when using httpproxy and json to load data:
Unexpected value NaN parsing y attribute.
Unexpected value NaN parsing height attribute.

Example:

var dataStore = {
    fields: ['Col1', 'Col2', 'time'],
    data: [{"Col1": 0, "Col2": 0, "time": "1200"},
           {"Col1": 0, "Col2": 0, "time": "1300"},
           {"Col1": 0, "Col2": 0, "time": "1400"},
           {"Col1": 0, "Col2": 0, "time": "1500"}
    ]
};

var display = Ext.create('Ext.chart.Chart', {
    width: 600,
    height: 800,
                flex: 1,
                animate: true,
                shadow: true,
                store: dataStore,
    legend: {
        position: 'bottom'
    },
    
       axes: [{
           type: 'Numeric',
           position: 'left',
           fields: ['Col1', 'Col2'],
           title: 'Y-axis',
           grid: true
       }, {
           type: 'Category',
           position: 'bottom',
           fields: ['time'],
           grid: true,
           title: 'X-axis'
       }],
       
       series: [{
           type: 'column',
           axis: 'left',
           gutter: 80,
           xField: ['time'],
           yField: ['Col1', 'Col2'],
       }]
});

var okWindow = Ext.create('Ext.Window', {
    title: 'Window',
    width: 800,
    height: 600,
    hidden: false,
    maximizable: true,
    renderTo: Ext.getBody(),
    layout: 'fit',
    items: [display]
});

i have similar issue though I can't locate the root cause. got following two warnings in firebug every times reloading the chart's store:


Unexpected value NaN parsing y attribute.
Unexpected value NaN parsing height attribute.
