如何解决高图 |如何避免标签内的饼图重叠

我正在使用 highcharts PIE，并想在切片上放置标签。但是，由于较小的值与相邻的较大值重叠。我已将“allowOverlap”属性设置为 false，这很有效，直到图表更新，例如悬停事件。

因此：

pie.series.dataLabel.allowOverlap=false

不会在更新之间持续存在。有没有办法处理这种情况？

参考文献：

1. 内部标签 - https://api.highcharts.com/highcharts/series.column.dataLabels.inside。
2. allowOverlap= false https://api.highcharts.com/highcharts/plotOptions.series.dataLabels.allowOverlap

解决方法

Pie 的系列类型没有 dataLabels.inside，请使用 dataLabels.distance 代替。 dataLabels.allowOverlap 没有记录在 pie 中。这可能解释了意外行为。

您似乎遇到了错误，我建议您提交错误报告 here。

禁用鼠标跟踪，可能是一个临时解决方案。

        Pie charts are very popular for showing a compact overview of a
        composition or comparison. While they can be harder to read than
        column charts,they remain a popular choice for small datasets.
