        yAxis: [{ // Primary yAxis
            labels: {
              //  format: '{value} Rs.',
                style: {

                }
            }
        }, { // Secondary yAxis
            title: {

                style: {
                    color: Highcharts.getOptions().colors[0]
                }
            },
            labels: {
                //format: '{value} out of 100',
                style: {
                    color: Highcharts.getOptions().colors[0]
                }
            },
            opposite: true
        }],
        tooltip: {
            shared: true
        },
        legend: {
            layout: 'vertical',
            align: 'left',
            x: 120,
            verticalAlign: 'top',
            y: 100,
            floating: true,
            backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'
        },
        series: [{
            name: 'Facility Rating',
            type: 'column',
            yAxis: 1,
            data: [],
            tooltip: {
                valueSuffix: ' out of 100'
            }

        }, {
            name: 'Bsp Cost',
            type: 'spline',
            data: [],
            tooltip: {
                valueSuffix: 'Rs.'
            }
        }]
    });

     $.getJSON("data.php", function(json) {

            options.xAxis.categories = json[0]['data'];
            options.series[0] = json[1];
            options.series[1] = json[2];

            chart = new Highcharts.Chart(options);

        });
});

});

This is my data.php.where i wrote my mysql query . i want in line chart shows the bsp cost that comes from 2nd query.and in column chart shows facilities total .with respective project.

<?php
include "connection.php";
$query1 = mysql_query("SELECT projects_detail.Project_name ,facility_rating.facilities_total 
FROM projects_detail LEFT OUTER JOIN facility_rating 
ON projects_detail.project_id= facility_rating.project_id 
ORDER BY facility_rating.facilities_total ASC LIMIT 0,15");

 $category = array();
 $category['name'] = 'Project';
 //$series1 = array();
 //$series1['name'] = 'Facilities Rating';

 while($row1 = mysql_fetch_array($query1)) {
    $category['data'][] = $row1['Project_name'];
  // $series1['data'][] = $row1['facilities_total'];
}

$query2 = mysql_query("SELECT projects_detail.Project_name,facility_rating.facilities_total,cost.bsp
FROM projects_detail LEFT OUTER JOIN facility_rating 
ON projects_detail.project_id= rfacility_rating.project_id 
LEFT OUTER JOIN cost ON facility_rating.project_id=cost.project_id 
ORDER BY facility_rating.facilities_total ASC LIMIT 0,15");
//$category = array();
 //$category['name'] = 'Project';
 $series1 = array();
 $series1['name'] = 'facility rating';
 $series2 = array();
 $series2['name'] = 'BSP VALUES';

while($row2 = mysql_fetch_array($query2)) {
    //$category['data'][] = $row2['Project_name'];
    $series1['data'][] = $row2['facilities_total'];
    $series2['data'][] = $row2['bsp'];
}
$result = array();
array_push($result,$category);
//array_push($result,$series1);
array_push($result,$series1);
array_push($result,$series2);

print json_encode($result, JSON_NUMERIC_CHECK);
//print json_encode($result2, JSON_NUMERIC_CHECK);
