Line chart not showing line

[bgeiger]

I'm trying to make a line chart with an xml store. Everything almost works, except I don't get a line. My axes are changing based on the data in my xml (so, for example, if my y variable goes from 0 to 25, it will show a different axis range than if my data goes from 0 to 100). So I know the store is working properly. I presume that the problem is in my line series, but I can't quite get it to do what I want.

Here's a snippet from my view code:

                           items: [
                                {
                                    xtype: 'chart',
                                    height: 250,
                                    id: 'TelemetryChart',
                                    width: 400,
                                    animate: true,
                                    insetPadding: 20,
                                    store: 'TelemetryHistoryStore',
                                    axes: [
                                        {
                                            type: 'Numeric',
                                            fields: [
                                                'speed'
                                            ],
                                            position: 'left',
                                            title: 'Speed'
                                        },
                                        {
                                            type: 'Time',
                                            fields: [
                                                'time'
                                            ],
                                            position: 'bottom',
                                            title: 'Time',
                                            dateFormat: 'H:i',
                                            step: [
                                                'mi',
                                                5
                                            ],
                                            groupBy: 'day,hour,minute'
                                        }
                                    ],
                                    series: [
                                        {
                                            type: 'line',
                                            title: 'SpeedSeries',
                                            xField: 'time',
                                            yField: [
                                                'speed'
                                            ]
                                        }
                                    ]
                                }
                            ]
                        },

And here's what I'm seeing:

Hopefully I'm just doing something done. I've tried several variations on the xField and yField, which seem like they'd be the culprits, but nothing's quite worked yet.

Thanks for any help,

Brian

So, no thoughts on this? Change a 0 to a 1? Missing a semicolon? Anything?
