Question

I am looking into using High Charts, but I want to populate the data dynamically with PHP and MySQL.
Looking for an easy way to get data from the DB into the jQuery functions.
This is how the points are created with jQuery (sorry for the big chunk of code).

<script type="text/javascript">

            var chart;
            $(document).ready(function() {
                chart = new Highcharts.Chart({
                    chart: {
                        renderTo: 'container',
                        defaultSeriesType: 'line',
                        marginRight: 130,
                        marginBottom: 25
                    },
                    title: {
                        text: 'Monthly Average Temperature',
                        x: -20 //center
                    },
                    subtitle: {
                        text: 'Source: WorldClimate.com',
                        x: -20
                    },
                    xAxis: {
                        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 
                            'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
                    },
                    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 +'°C';
                        }
                    },
                    legend: {
                        layout: 'vertical',
                        align: 'right',
                        verticalAlign: 'top',
                        x: -10,
                        y: 100,
                        borderWidth: 0
                    },
                    series: [{
                        name: 'Tokyo',
                        data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
                    }, {
                        name: 'New York',
                        data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
                    }, {
                        name: 'Berlin',
                        data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
                    }, {
                        name: 'London',
                        data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
                    }]
                });


            });

        </script>

The Highcharts documentation is excellent, I would start there. This is likely the type of graph you want:

http://www.highcharts.com/demo/dynamic-update

And you want to mess with the Point object:

http://www.highcharts.com/ref/#point-object

You are going to want to add the data using jQuery .post or .get commands to get the data from the server.
