Additional Chart in Tooltip possible?

Question

Has anyone ever tried to insert another chart with completely different data to the tooltip which is popping up when hovering over data points? I have checked the possibilty to pass html to the formatter, but not sure how dynamically this is working.

I have a bubble chart and it would be perfect to add small line charts to the tooltips of the bubbles.

Yes, it is possible.

If you set tooltip's useHTML to true and create a chart in it, then you will get a chart in a tooltip.

Example: http://jsfiddle.net/n9z7r5uj/

$(function() {
  $('#container').highcharts({
    series: [{
      type: 'bubble',
      data: [[1,2,3],[4,1,6],[2,3,9]]
    }],
    tooltip: {
      useHTML: true,
      pointFormatter: function() {
        var data = [this.x, this.y, this.z];
        setTimeout(function() {
          $('#chart').highcharts({
            title: {
                text: ''
            },
            legend: {
                enabled: false
            },
            credits: {
                enabled: false
            },
            series: [{
                animation: false,
              data: data
            }],
            yAxis: {
                title: ''
            },
            xAxis: {
                categories: ['x','y','z']
            }
          });
        }, 0);
        return '<div id="chart" style="width: 100px; height: 150px;"></div>';
      }
    }
  });
});
