Disable highcharts tooltip on certain lines, leave it enabled on others? - highcharts

Question

I have a Highchart containing multiple lines. I want to disable the tooltip on certain lines, and leave it enabled for others. Is that possible? I see how to disable the tooltip globally, but not by series.
For instance, on the standard line chart example is it possible to disable the tooltip on the red and blue lines but leave it enabled on the other two?

Use enableMouseTracking. It's the best way to do it.
Per Serie
series: [{
name: 'Serie1',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6],
enableMouseTracking: false
}, {
name: 'Serie2',
data: [7.0, 6.9, 9.5, 15.5, 15.2, 15.5, 15.2, 15.5, 11.3, 17.3, 11.9, 9.6]
}]
Global
plotOptions: {
series: {
enableMouseTracking: false
}
}
The code above will display tooltip for only the first serie.

For stock charts enableMouseTracking: false makes lines inactive on hover.
Here's better solution:
Highcharts.chart('container', {
series: [{
name: 'John',
type: 'column',
data: [5, 3, 4, 7, 2],
tooltip: {
pointFormatter: function() {
return false
}
}
}, {
name: 'Jane',
type: 'column',
data: [2, 2, 3, 2, 1],
tooltip: {
pointFormatter: function() {
return 'Second <strong>column</strong> series.'
}
}
}, {
name: 'Joe',
type: 'line',
data: [3, 4, 4, 2, 5],
tooltip: {
pointFormatter: function() {
return false
}
}
}]
});
