How to create Highcharts pareto with drilldown - highcharts

Question

I want to create a pareto with drilldown. I'm able to create the drilldown, but the pareto line doesn't appear on the graph. Is there a demo of how to do this so that I can use that as an example?
This in an example of the code that I wrote, the drilldown works, but the pareto line doesn't appear.
series: [
{
type: 'pareto',
name: 'Pareto',
yAxis: 1,
zIndex: 10,
color: 'orange',
baseSeries: 1,
tooltip: {
valueDecimals: 2,
valueSuffix: '%'
},
{
name: 'Example',
type: 'column',
data: [{}
<?php foreach($Example1 as $m => $a): ?>
,{
name: '<?php echo $m ?>',
y: <?php echo $a['Qty'] ?>,
drilldown: '<?php echo $m ?>'
}
<?php endforeach ?>
],
dataLabels: {
enabled: true,
color: '#FFFFFF',
align: 'center',
format: '{point.y}',
style: {
color: 'white',
fontSize: '15px',
}
}
}],
drilldown: {
series: [{}
<?php foreach ($Example1 as $m => $a): ?>
,{
name: '<?php echo $m ?>',
id: '<?php echo $m ?>',
data: [
<?php foreach ($Example2 as $r): ?>
<?php if ($r['Example'] == $m): ?>
['<?php echo $r['ExampleExample'] ?>', <?php echo $r['Qty'] ?>],
<?php endif ?>
<?php endforeach ?>
]
}
<?php endforeach ?>
]
