问题


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
