Improve highcharts performance for large amounts of data

Question

I am trying to get a larger amount of data. Sample data is below

1850/01   -0.845   -0.922   -0.748   -1.038   -0.652   -1.379   -0.311   -1.053   -0.636   -1.41         


        

Answer 1

I'd use underscore.js.

 var result = _.map(lines, function (row) {
    return { type: 'line', series: _.map(row.data, function (item, index) {
      if (index >= 1)
        return parseFloat(item);
    }), name: row.data[0]}
  });
