This is the high chart graph code.

Answer 1

You can use this Plugin that I believe will do what you want to.

$(function() {

    $.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json&callback=?', function(data) {
        $('#container').highcharts('StockChart', {

            title : {
                text : 'AAPL Stock Price'
            },

            subtitle: {
                text: 'From may 15, 2006 to May 10, 2013'
            },
            
            xAxis: {
                ordinal: false
            },

            yAxis: {
                title : {
                    text : 'Price'
                }
            },

            legend: {
                enabled: true,
                layout: 'vertical',
                align: 'right',
                verticalAlign: 'middle',
                borderWidth: 0
            },
            
            series : [{
                name: 'Stock Price',
                type : 'line',
                id: 'primary',
                data : data
            }, {
                name: 'Linear Trendline',
                linkedTo: 'primary',
                showInLegend: true,
                enableMouseTracking: false,
                type: 'trendline',
                algorithm: 'linear'
            }]
        });
    });

});
