I have a plugin to display data using Highstock charts in my channels. In order to get the data to feed the plots I am using the command $.getJSON (similar to what the Multiple series example does). The problem is that the command $.getJSON is only able to request 1000 data points (I have tried to change its input for higher values in 'results=1000' but that does not work). Any idea on how can get more than 1000 points in my graphs?

This is the code that I am using:

$(function () {
  var my_offset = new Date().getTimezoneOffset();
    $.getJSON('https://api.thingspeak.com/channels/239388/fields/2.json?results=1000&api_key=', function (data) {
    var field_name = 'field' + 2;   
  // iterate through each feed
    var chart_data = [];  

    $.each(data.feeds, function() {
         var point = new Highcharts.Point();
         var value = this[field_name];
         point.x = Date.parse(this.created_at) - (my_offset * 60000);


Thank you very much for your help!

A good way to find out about the root cause of the problem here is to use a public channel and see whether $.getJSON is able to request more than 1000 data points.

I used the Channel ID 9 to find out whether $.getJSON works with more than 1000 data points. Below is the API request:


Output -> 1100

A most probable reason for you not getting more than 1000 data points could be insufficient number of data points in your channel.

Try to find out the exact number of data points in your channel, and see whether the results parameter has a number <= the number of data points.

Do let me know if this doesn't help.
