Highcharts, button to redraw stackedcolumn - highcharts

Question

I am bringing in to my chart json objects, indexed two different ways.
I have a button to flip my index, and it works in the sense that my catagories will flip back and forth, but my new data does not...
var $chart_data = data[1];
$button = $('#button');
var chart_ops_support_times = new Highcharts.Chart({
chart: {
renderTo: 'chart_ops_support_times',
type: 'column'
},
title: {
useHTML: true,
text: '',
align: 'left'
},
subtitle: {
text: ' '
},
xAxis: {
categories: [
'priority 1',
'priority 2',
'priority 3'
]
},
yAxis: {
min: 0,
max: 60,
title: {
text: 'Total Actual Hours by Type',
style: {
fontSize: '8px',
fontWeight: 'normal'
}
},
stackLabels: {
enabled: false,
style: {
fontWeight: 'bold'
}
}
},
legend: {
align: 'center',
x: 0,
verticalAlign: 'top',
y: 0,
floating: true,
borderColor: '#CCC',
borderWidth: 1,
shadow: false,
symbolHeight: 10,
symbolWidth: 10
},
credits: {
enabled: false
},
tooltip: {
formatter: function () {
return '<b>' + this.x + '</b><br/>' +
this.series.name + ': ' + this.y + '<br/>' +
'Total: ' + this.point.stackTotal;
}
},
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: false,
style: {
textShadow: '0 0 3px black'
}
}
}
},
exporting: {
enabled: false
},
series: $chart_data
});
$button.click(function() {
if (!flipxAxis) {
console.log('flip to priority x axis');
chart_ops_support_times.xAxis[0].categories = priority_bkts ;
chart_ops_support_times.series[0].update({
dataLabels: {
enabled: true
},
series: data[0]
});
chart_ops_support_times.redraw();
} else {
console.log('flip to time span x axis');
chart_ops_support_times.xAxis[0].categories = time_span_bkts;
chart_ops_support_times.series[0].update({
dataLabels: {
enabled: false
},
series: data[1]
});
chart_ops_support_times.redraw();
}
flipxAxis = !flipxAxis;
});
}
I have put in the swap of datalabels just to test if the update is firing, and it is...
