I am trying to customize the tooltip in a highcharts bubble chart. Rather than having just the figures appear in the tooltip, I'd like to add context based on the x,y and z titles (ex, "50 fatalities, 100 injured, 150 total victims" instead of the current "(50,150) Size: 150" display). I'm able to make this happen in scatter plot charts using the following, but no dice in bubbles. Any ideas? Thanks. :)
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: '{point.x} fatalities, {point.y} injured, {point.z} total'
}
