[英]Add a custom text tooltip that differs from point to point in Highcharts
I am trying to develop a chart that displays a custom 'text' tooltip that I can set to change from point to point. 我正在尝试开发一个显示自定义“文本”工具提示的图表,我可以将其设置为逐点更改。 Here is my code as of now:
到目前为止,这是我的代码:
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: '{point.x:%e. %b}: {point.y:.2f} m'
},
series: [{
name: 'Winter 2007-2008',
data: [
[Date.UTC(1970, 9, 27), 0 ],
[Date.UTC(1970, 10, 10), 0.6 ],
[Date.UTC(1970, 10, 18), 0.7 ],
[Date.UTC(1970, 11, 2), 0.8 ],
[Date.UTC(1970, 11, 9), 0.6 ],
[Date.UTC(1970, 11, 16), 0.6 ],
[Date.UTC(1970, 11, 28), 0.67],
[Date.UTC(1971, 0, 1), 0.81]
]
}
Now this works as intended, but I am trying to add an extra bit of text that will appear in the tooltip when hovering over a point. 现在,这可以按预期工作,但是我想添加一些额外的文本,当将鼠标悬停在某个点上时,这些文本会显示在工具提示中。 This is my desired input for a data point (although I dont know if I will have to change it for my final product).
这是我想要的数据点输入(尽管我不知道是否需要为最终产品进行更改)。
[Date.UTC(1970, 10, 18), 0.7 , 'custom tooltip1'],
[Date.UTC(1970, 10, 18), 0.7 , 'custom tooltip2'],
I would want the text displayed in a newline below the current tooltip: 我希望文本显示在当前工具提示下方的换行符中:
Please let me know if you have any suggestions or can point me somewhere I can find some answers. 如果您有任何建议,或可以指出我可以找到一些答案的地方,请告诉我。
Thanks! 谢谢!
Change your data to be something like this: 将您的数据更改为如下所示:
data: [
{x: Date.UTC(1970, 10, 18),
y: 0.7 ,
customtooltip: 'custom tooltip1'},
{x: Date.UTC(1970, 10, 18),
y: 0.7 ,
customtooltip: 'custom tooltip2'}
]
Then in do a tooltip formatter function like this: 然后执行以下工具提示格式化程序功能:
tooltip: {
formatter: function() {
var dt = new Date(this.x);
var months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"];
var dtstr = dt.getDate()+". "+months[dt.getMonth()];
var tooltip = '<b>'+this.series.name+'</b><br>'+dtstr+': '+this.y+' m<br>'+this.point.options.customtooltip;
return tooltip;
}
}
See how that works for you. 看看如何为您工作。
