[Ext: 4.2.0 Beta2] - Creating a chart without a series

[fordprefect]

Hello,

I'm just attempting to move to 4.2 from 4.1.1 and I'm having some issues with how I've been creating charts. I have a generic chart definition (line chart for example) that includes a chart skeleton but no series like so:

Ext.define('MyApp.view.chart.charts.LineChart', {
    extend: 'Ext.container.Container',
    alias: 'widget.linechart',


    uses: [
        'Ext.data.JsonStore',
        'Ext.chart.*',
        'Ext.fx.target.Sprite',
        'Ext.layout.container.Fit'
    ],


    border: false,


    initComponent: function () {
        Ext.apply(this, {
            layout: 'fit',
            items: {
                xtype: 'chart',
                animate: false,
                store: 'ChartStore',
                border: false,
                insetPadding: 20,
                height: 375,
                legend: {
                    position: 'bottom'
                },
                axes: [{
                    type: 'Numeric',
                    position: 'left',
                    fields: [],
                    minorTickSteps: 1
                }, {
                    type: 'Category',
                    position: 'bottom',
                    fields: ['DisplayText'],
                    label: {
                        rotate: {
                            degrees: 270
                        }
                    }
                }]
            }
        });
        this.callParent(arguments);
    }
});

I would then create the chart:

var myChart = Ext.create('MyApp.view.chart.charts.LineChart');

However at this point I'm getting an error thrown:

TypeError: series[0] is undefined

I'm assuming it's no longer possible to create a chart without a series? Previously I would do the above and then iterate through the store adding any records in the store for a series, this way I wouldn't have to declare what items would be in the series since it would vary:

Ext.iterate(record, function (key, value) {
 chart.series.add({ type: 'line', axis: 'left', smooth: true, xField: 'DisplayText', yField: key, title: key});
});

Thanks

Sounds like a bug was introduced. Normally you should specify the series but not all use cases want this to be.

I have opened a bug in our bug tracker.
