<script type='text/javascript' src='https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js'></script>
<script type='text/javascript' src='https://www.google.com/jsapi'></script>
<script type='text/javascript'>

// set your channel id here
var channel_id = xxxxxxx;
// set your channel's read api key here if necessary
var api_key = 'xxxxxxx';
// maximum value for the gauge
var max_gauge_value = 1060;
// name of the gauge
var gauge_name = 'P [mBar]';

// global variables
var chart, charts, data;

// load the google gauge visualization
google.load('visualization', '1', {packages:['gauge']});
google.setOnLoadCallback(initChart);

// display the data
function displayData(point) {

data.setValue(0, 0, gauge_name);
data.setValue(0, 1, point);
chart.draw(data, options);
}

// load the data
function loadData() {

// variable for the data point
var p;

// get the data from thingspeak
$.getJSON('https://api.thingspeak.com/channels/' + channel_id + '/feed/last.json?api_key=' + api_key, function(data) {

// get the data point
