Whenever I change the old value of the highchart with a new value, the highchart still displays the old value.
Each time I need to refresh before new value has been added and displayed to the highchart but I dont know why. Can someone help me how to solve this?
Following is my jQueryportion of code for displaying the chart that uses the Highcharts plugin.
//charts
// JavaScript Document
$(function() {
var chart;
$(document).ready(function() {
$.getJSON("../php/termocouple/line_temp1.php", function(json) {
chart = new Highcharts.Chart({
chart: {
renderTo: 'chart1',
type: 'line'
},
title: {
text: 'Termocouple Graph Result'
},
subtitle: {
text: ''
},
xAxis: {
title: {
text: 'Sensor'
},
categories: ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function() {
return '<b>' + this.series.name + '</b><br/>' +
this.x + ': ' + this.y;
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 120,
borderWidth: 0
},
series: json
});
});
});
});
and here is the PHP backend code that processes and provides data to Highcharts
