在Highcharts工具提示系列名称前面的奇怪字符 [英] Weird character in front of Highcharts tooltip series names

问题描述

我有一个Highcharts图表，由于某种原因，在系列标题之前只显示数据点弹出的奇数字符。我使用默认弹出窗口和highcharts 4.0.1。

I have a Highcharts chart which is, for some reason, showing odd characters before the series title only on the data point pop up. I am using the default popup and highcharts 4.0.1.

我目前设置所有系列的标题 hi 以确保我的代码中没有什么是搞砸这个。此外，如果我输出 countsGraph.series [0] .name 我也得到 hi 。

I currently set all series to have the title hi to ensure nothing in my code was messing this up. Also if I output countsGraph.series[0].name I also get hi.

是什么原因造成的？不幸的是，我现在不能做一个小提琴，因为我访问HighCharts.com正在播放。

What is causing this? Unfortunately I cannot make a fiddle at the moment as my access to HighCharts.com is playing up.

这是我如何创建系列

// Create new series if requried
if (!series[c]) {
    series[c] = {
        name: "hi",
        data: []
    };
}

推荐答案

很可能你使用的编码不同于UTF- 。您只需删除该字符即可，只需更改 pointFormat ，从：

Most probably you are using different coding than UTF-8. You can simply remove that character, by changing pointFormat, from:

<span style="color:{series.color}">\u25CF</span> {series.name}: <b>{point.y}</b><br/>

到：

<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b><br/>

或者，因为 @Adam Goodwin 在选项中设置默认格式：

Or, as just @Adam Goodwin pointed out, set default format in your options:

<span style="color:{series.color}">\u25CF</span> {series.name}: <b>{point.y}</b><br/>
