绘制图表后,从图表对象更改Highcharts工具提示格式器 [英] Change Highcharts tooltip formatter from chart Object , after chart is rendered
问题描述
我发现我可以使用setData更改系列,并且我知道我可以使用.setExtremes修改Max值,但我无法弄清楚如何从图表对象设置工具提示格式器。
如何更新该栏位?
如果我有一个图表对象,我该如何更新其工具提示格式器属性?以及plotOptions工具提示格式化程序如何?
我曾尝试过:
chart1.tooltip.formatter = function(){return''+ this.series.name +'example:'+ this.y +'example';};
但是我在图表定义(用于测试)之后添加了我的工具提示时没有任何更改。
另外,我注意到这个
console.log(chart1.tooltip.formatter);
返回undefined,但我不知道为什么。
小提琴让您可以尝试一下。

在此先感谢。
您可以使用 chart.tooltip.options.formatter
像
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 />');
}

更新
在高图的新版本(5.0.0+)这也可以使用 chart.update()$ c
chart.update({
tooltip:{
formatter:函数(){
var xyArr = [];
$ .each(this.points,function(){
xyArr.push('Serie:'+ this.series.name +' ,'+'X:'+ this.x +',Y:'+ this.y);
});
return xyArr.join('< br />');
}
}
});

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/>');
}
}
});
