highcharts stockchart 1m and 3m not enabled - highcharts

Question

Please refer to http://jsfiddle.net/a6h6cLnt/. The '3m' and '1m' buttons are not working. Earlier with a smaller dataset, none of the zoom buttons were working. The url to the smaller dataset is http://jsfiddle.net/a6h6cLnt/1/
$(function () {
var seriesOptions = [],
seriesCounter = 0,
names = ['MSFT'],
// create the chart when all data is loaded
createChart = function () {
$('#container').highcharts('StockChart', {
rangeSelector: {
selected: 4
},
yAxis: {
labels: {
formatter: function () {
return (this.value > 0 ? ' + ' : '') + this.value + '%';
}
},
plotLines: [{
value: 0,
width: 2,
color: 'silver'
}]
},
plotOptions: {
series: {
compare: 'percent'
}
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b> ({point.change}%)<br/>',
valueDecimals: 2
},
series: seriesOptions
});
};
$.each(names, function (i, name) {
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=' + name.toLowerCase() + '-c.json&callback=?', function (data) {
seriesOptions[i] = {
name: name,
data: [[1346371200000,12],[1348963200000,13],[1354233600000,4],[1377907200000,12],[1380499200000,13],[1385769600000,4],[1406764800000,1],[1409443200000,15],[1412035200000,20],[1414713600000,2],[1417305600000,4]]
};
// As we're loading the data asynchronously, we don't know what order it will arrive. So
// we keep a counter and create the chart when all the data is loaded.
seriesCounter += 1;
if (seriesCounter === names.length) {
createChart();
}
});
});
});

<div id="container" style="height: 400px; min-width: 310px"></div>
The '1m' and '3m' zoom buttons/links are not working.
Please let me know how to enable them or make them work

Answer 1

You need to set minRange parameter to define minimum zoom.
