如何禁用highcharts-regression插件的工具提示？

Question

I've created a simple Highcharts scatter plot with three data points. It uses the highcharts-regression plug-in to add a series showing the linear regression line. I would like tooltips to display for the data points but not for the regression line, so I have disabled the tooltip like this:

series: [{
  regression: true,
  name: 'Test input',
  color: 'rgba(223, 83, 83, .5)',
  data: [
    [1, 1],
    [2, 3],
    [3, 9],       
  ],
  regressionSettings: {
    tooltip: {
      enabled: false // <---- I expect this to disable the tooltip
    },
  }
}]

http://jsfiddle.net/f34mza2q/1/

As you can see from the jsfiddle, the tooltips still pop up for the regression line. How can I turn off the tooltips here (and still keep them for the data points)?

I've tried a couple of other things:

• adding a style: 'display: "none"' to regressionSettings.tooltip
• setting regressionSettings.enableMouseTracking to false

Neither seemed to have any effect.

UPDATE: Based on ppotaczek's answer below, here's what I did to turn off tooltips for all regression lines on the chart:

Highcharts.chart('mychart', {
    // ...
    events: {
        load: function() {
            var trendlines = this.series.filter(c => c.options.isRegressionLine);
            for (i in trendlines) {
                trendlines[i].update({
                    enableMouseTracking: false
                });
            }
        }
    },
    //...
});

This highcharts-regression plugin is not official Highcharts plugin, but please look at the documentation: https://api.highcharts.com/highcharts/series.line.tooltip , you can not disable tooltip for individual series in the way you try. You should use enableMouseTracking property, but it is not supported in regressionSettings . To workaround, you can use update method on created regression series in this way:

            load: function() {
                this.series[1].update({
                    enableMouseTracking: false
                });
            }

as mentioned in documentation HIGHCHARTS REGRESSION the tooltip object fellow the stander configuration of highchart disabling or enabling for the entire chart. unless you want to search the generated html/css and remove the tooltips with jquery.
