Highcharts combination of line chart and treemap - highcharts

Question

I need to make a combination of draggable line chart and treemap.
See here: JSFiddle example
Highcharts.chart('container', {
series: [{
type: "treemap",
data: [
{id: "NS",name: 'NS_area', value:5},
// ...
}
},{
data: [[0, 100], [10,90.9], [20,81.8], [30,72.7]],
type: 'line',
}]
});
can I display x,y axis when using treemap? Do you have other idea how to combine both charts?

Answer 1

One workaround that might work for you is adding an additional axis and simply linking it to the original one.
For example, creating one "duplicate" x-axis and y-axis:
xAxis: [{
},{
linkedTo: 0
}],
yAxis: [{
}, {
linkedTo: 0
}]
See this JSFiddle demonstration of it in use. This makes the axis mimic the look you originally had.
If you want the line chart to be completely independent of the original axis, you could just do the following:
series: [{
// ...
}, {
data: [[0, 100], [10,90.9], [20,81.8], [30,72.7]],
type: 'line',
yAxis: 1,
xAxis: 1,
// ...
}],
xAxis: [{
},{
}],
yAxis: [{
}, {
}],
See this JSFiddle demonstration of it in use. This works as a completely separate axis.
