I have found that I can change series with setData, and I know I can modify Max values with .setExtremes , but I cannot figure out how to set the tooltip formatter from the chart object. How do I update that field ? If i have a chart object , how do I update its tooltip formatter property ? and How about the plotOptions tooltip formatter?
What I have tried :
chart1.tooltip.formatter = function() {return ''+this.series.name +'example: '+ this.y +'example';};
But nothing changed in my tooltips when i added that after the chart definition (for testing). Also, I noted that this
console.log (chart1.tooltip.formatter);
returns undefined, but I don't know why.
Fiddle so you can try it out.

You can use chart.tooltip.options.formatter
instead, like
chart.tooltip.options.formatter = function() {
var xyArr=[];
$.each(this.points,function(){
xyArr.push('Serie: ' + this.series.name + ', ' +'X: ' + this.x + ', Y: ' +this.y);
});
return xyArr.join('<br/>');
}

UPDATE
In new (5.0.0+) versions of highcharts, this can also be done using the chart.update()
method
chart.update({
tooltip: {
formatter: function() {
var xyArr = [];
$.each(this.points, function() {
xyArr.push('Serie: ' + this.series.name + ', ' + 'X: ' + this.x + ', Y: ' + this.y);
});
return xyArr.join('<br/>');
}
}
});
