I have this Highcharts timeline and I want to rename the series labels to be more descriptive (instead of displaying 'Series 1', 'Series 2', etc) in other words, a meaningful label name.
I thought it was as simple as adding brackets and calling the name property, but this fails to render. This is troublesome, since this is the only documentation I can find on naming series in Highcharts.
Here is the code:
<script>
(function(H) {
H.seriesTypes.timeline.prototype.getXExtremes = function(xData) {
var series = this;
return {
min: H.arrayMin(xData),
max: H.arrayMax(xData)
};
}
}(Highcharts));
Highcharts.dateFormats = {
q: function(timestamp) {
var date = new Date(timestamp),
quarter = (Math.floor(date.getUTCMonth() / 3) + 1);
return quarter;
}
};
Highcharts.chart('container', {
chart: {
zoomType: 'x',
type: 'timeline'
},
//xAxis: {
//type: 'datetime',
//visible: true
//},
xAxis: {

['month', [3, 6]],
['year', [1]]
],

//rotation: -30
}

Thanks for any help.
