Non-contiguous time series in Highcharts

Question

I would like to create a zoomable time series chart of the number of Tweets that an an account posted per day. My server returns data for the dates where Tweets occurred, that looks like this:

[

 "2009-01-12", 3 

], [

 "2009-01-15", 1 

], [

 "2009-01-16", 1 

], [

 "2009-01-30", 2 

]

I know that the ISO 8601 date can be converted with Date.parsedate() . Can I register it as a callback to convert the dates? How can I create a zoomable chart with irrigular intervals?

Answer 1

You just need to loop through your array and parse that date to get timestamp, for example:

var parsedDate = [];
for(var i = 0; i < your_array.length; i++){
    var t = your_array[i],
        d = (new Date(t[0])).getTime();
    parsedData.push([d, t[1]]);
}

And then assign to series data in options:

series: [{
    data: parsedData;
}]
