高图表测量不需要的白色边框

我想出了一个在 JSFiddle 上呈现非常好的高图表仪表代码，但是当我将其复制/粘贴到我的网站时，似乎所有"边框"选项（borderColor 和 borderWidth）都没有响应，浏览器会自动在我的系列、工具提示和仪表的几个背景半径上放置白色边框，这是我不想要的， 这不仅给人一种糟糕的视觉效果，而且还阻止了该系列的清晰显示！

这是JSFiddle： https://jsfiddle.net/roamdam/p67ebL0L/6/

var legend1 = "<span style='font-weight:100'>Un peu</span>",
    legend2 = "<span style='font-weight:100'>Beaucoup</span>",
    legend3 = "<span style='font-weight:100'>Pas du <br/>tout</span>";
