如何使用刷新

标签： php jquery json highcharts

每当我使用新值更改高图的旧值时，高图仍会显示旧值。

每次我需要在新值添加并显示到高图之前刷新，但我不知道为什么。有人可以帮我解决这个问题吗？

以下是我的jQuery部分代码，用于显示使用Highcharts插件的图表。

//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
            });
        });
    });
});

这里是PHP后端代码，用于处理和向Highcharts提供数据

我现在得到了答案。 我只需要调用图形两个函数。 使用php的第一个函数，只是在没有where子句的情况下调用display函数 用php调用display子函数的第二个函数用where子句

我只是在脚本上调用redraw来显示高图。
