highcharts, json data: line and column

May be really basic question:

I'm playing with highcharts with two series, one represented with line and other with column, data is loaded using json, the problem is in how to tell highcharts one serie should be represented with line and the other with column type, like this

The problem (for me) comes when Series options in json mode of highcharts are only like this:

         }, 
            series: json
        });

whilst in "normal mode" you can set for example:

    series: [{
**type: 'column',**
    name: 'Name',
    data: [],
},{
type: 'spline',
    name: 'Max Pax',
    data: [],
draggableY: true,
dragMinY: 0,
    dragMaxY: 200,
    .......

Am I missing something?

php code that retrives data from db:

    $con = mysql_connect("localhost", "*******","*******");

if (!$con) {
die('Could not connect: ' . mysql_error());
}

mysql_select_db("wordpress_8", $con);

$sth = mysql_query("SELECT * FROM wp_maxpax_A where fecha='12/11/2013' ");
$rows = array();
$rows['name'] = 'MaxPax';
while($r = mysql_fetch_array($sth)) {
$rows['data'][] = $r['a1300'];
$rows['data'][] = $r['a1315'];
$rows['data'][] = $r['a1330'];
$rows['data'][] = $r['a1345'];

}

$sth = mysql_query("SELECT overhead FROM projections_sample");
$rows1 = array();
$rows1['name'] = 'Overhead';
while($rr = mysql_fetch_assoc($sth)) {
$rows1['data'][] = $rr['overhead'];
}

$result = array();
array_push($result,$rows);
array_push($result,$rows1);


print json_encode($result, JSON_NUMERIC_CHECK);

Output looks like:

    [{"name":"MaxPax","data":[40,19,40,21]},{"name":"Overhead","data":                 [21990,22365,21987,22369,22558,22987,23521,23003,22756,23112,22987,22897]}]

You need to define this parameter in JSON, or parse your json after receive, and set this paraemter, then use in Highcharts.

EDIT: You can replace this lines

$sth = mysql_query("SELECT * FROM wp_maxpax_A where fecha='12/11/2013' ");
$rows = array();
$rows['name'] = 'MaxPax';

with

$sth = mysql_query("SELECT * FROM wp_maxpax_A where fecha='12/11/2013' ");
$rows = array();
$rows['name'] = 'MaxPax';
$rows['type'] = 'line';

Similar in next series. Second solution is push type after getting json like:

$getJSON('path/to/json',function(data){


 data[0].type='column';
 data[1].type='line';

 var options = {
    // your options
    series: data
 };

 $('#container').highcharts(options);
});
