highcharts圆环图中心文本与工具提示重叠-Java 学习之路

我在Highcharts Donut / Pie图表的中心显示文字 . 但我的问题是中心文本与工具提示文本重叠，工具提示变得不可读 .

我已经尝试更改工具提示的zIndex将它带到前面，但它不起作用 . 我希望工具提示位于甜甜圈中心文本之上 .

尝试以下将解决您的问题：

CSS:

.highcharts-tooltip span {
    background-color:white;
    border:1px solid;
    opacity:1;
    z-index:9999 !important;
}

JQuery:

tooltip: {
           borderWidth: 0,
           backgroundColor: "rgba(255,255,255,0)",
           shadow: false,
           useHTML: true,
           //zIndex: 99, //on top of everything
           headerFormat: '',
           pointFormat: '{point.actualCounts} {point.name}'
         },
