本文介绍了动态highcharts使用JSON数据的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我米试图弄清楚这是有可能使JSON数据动态获取从数据库PHP和MySQL的帮助下,可与highcharts太动态自动更新绘制?任何帮助将是AP preciated。

下面的$ C $词都试过,不正常工作,要落实到网站为10行。

                移= series.data.length> 20; //如果偏移的系列
                                                 //长于2

            变种系列2 = chart.series [1],
                移= series2.data.length> 20; //如果偏移的系列
                                                 //长于20

            //添加点
            chart.series [1] .addPoint(点,真实,移);

            //一秒钟后再次调用它

         ***实况服务器data.php是如下:
    < PHP
//设置JSON头
标题(内容类型:文本/ JSON);

// x值是当前的JavaScript的时间,这是Unix时间乘以
// 1000。
$ X =时间()* 1000;
// y值是随机数
$ Y =兰特(48,52);
//创建一个PHP数组和回声它作为JSON
$ RET =阵列($ X,$ Y);
回声json_en code($ RET);
?>
 

解决方案

您可以使用

尝试

  VAR选项= {
        图表: {
            renderTo:图表,
        },
        学分:{
            启用:假的
        },
        标题: {
            文本:林pression /点击概览,
            X:-20
        },
        x轴:{
            类别:[{}]
        },
        提示:{
            格式:函数(){
                VAR S ='< B>+ this.x +'< / B>';

                $每个(this.points,功能(我,点){
                    S + ='< BR />+ point.series.name +:+ point.y;
                });

                返回S;
            },
            共享:真
        },
        系列: [{},{}]
    };

    $阿贾克斯({
        网址:json.php
        数据:'秀= IM pression',
        类型:'后',
        数据类型:JSON,
        成功:功能(数据){
            options.xAxis.categories = data.categories;
            options.series [0]。名称='林pression';
            options.series [0] .DATA = data.im pression;
            options.series [1]。名称='点击';
            options.series [1] .DATA = data.clicks;
            VAR图=新Highcharts.Chart(选件);
        }
    });
 

I m trying to figure it out that is it possible to make the json data fetched dynamically from a database with the help of php and mysql and can be plotted with highcharts that too dynamic auto updating? Any help would be appreciated.

following the code i have tried and is not working properly and want to implement to the the website for 10 lines.

    $.ajax({
        url: 'live-server-data.php',
        success: function(point) {
            var series = chart.series[0],
                shift = series.data.length > 20; // shift if the series is 
                                                 // longer than 2

            chart.series[0].addPoint(point, true, shift);

            // call it again after one second
            setTimeout(requestData1, 1000);

        cache: false,

    });

}

         *** the live-server-data.php is as followed:
    <?php

header("Content-type: text/json");

// The x value is the current JavaScript time, which is the Unix time multiplied 
// by 1000.
$x = time() * 1000;
// The y value is a random number
$y = rand(48,52);
// Create a PHP array and echo it as JSON
$ret = array($x, $y);
echo json_encode($ret);
?>

解决方案

You can try with

var options = {
        chart: {
            renderTo: 'chart',
        },
        credits: {
            enabled: false
        },
        title: {
            text: 'Impression/Click Overview',
            x: -20
        },
        xAxis: {
            categories: [{}]
        },
        tooltip: {
            formatter: function() {
                var s = '<b>'+ this.x +'</b>';

                $.each(this.points, function(i, point) {
                    s += '<br/>'+point.series.name+': '+point.y;
                });

                return s;
            },
            shared: true
        },
        series: [{},{}]
    };

    $.ajax({
        url: "json.php",
        data: 'show=impression',
        type:'post',
        dataType: "json",
        success: function(data){
            options.xAxis.categories = data.categories;
            options.series[0].name = 'Impression';
            options.series[0].data = data.impression;
            options.series[1].name = 'Click';
            options.series[1].data = data.clicks;
            var chart = new Highcharts.Chart(options);          
        }
    });
