Highcharts-如何将工具提示悬停在每个饼图上的图标后面？

Question

我需要以下方面的帮助：

要将html标签放在每个饼图切片上（元素+类显示图标），并将其放置在悬停工具提示的后面？

目前，我有这个：

                          var chart = new Highcharts.Chart({
                            chart: {
                                renderTo: 'modules',
                                plotBackgroundColor: null,
                                plotBorderWidth: null,
                                plotShadow: false,
                                type: 'pie',
                                backgroundColor:"transparent"
                            },
                            credits:{
                                enabled:false
                            },
                            exporting: {
                                enabled: false
                            },
                            title: {
                                text: '',
                                style: {
                                    fontSize: '20px',
                                    color: '#999999',

                                    fontFamily: 'Verdana'
                                }
                            },
                            subtitle:{
                                text: '',
                                style: {
                                    fontSize: '15px',

如果将鼠标悬停在每个切片上，工具提示将位于超棒字体图标的后面吗？

能落后吗？

Answer 1

您需要使用html工具提示而不是svg工具提示。 将tooltip.useHTML设置为true。

禁用工具提示的svg框

tooltip: {
  borderWidth: 0,
  borderColor: null,
  borderRadius: 0,
  shadow: false,
  backgroundColor: "none",
  useHTML: true,

在CSS中设置样式：

.highcharts-tooltip > span {
  padding: 5px;
  background-color: rgba(0,0,0,0.8);
  background-color: white\9;
  /* < IE11 */
  border: 1px solid #a8a7a5;
  z-index: 9999;
}
