我有一个简单的sankey高图图表。我正在使用示例数据进行绘制,一切工作都很好,但是当我增加datalabels的字体大小而不显示所有数据时,这是一个小问题。当我只悬停其显示时。有什么解决方案吗?这是下面的代码。我也在导出选项中控制字体大小。
<script src="https://code.highcharts.com/highcharts.js"></script>

<div id="container"></div>
Highcharts.chart('container', {
title: {
text: 'Highcharts Sankey Diagram'
},
accessibility: {
point: {
valueDescriptionFormat: '{index}. {point.from} to {point.to}, {point.weight}.'
}
},
exporting: {
chartOptions: {

dataLabels: {

fontSize: "6px",
fontWeight: "normal"
}
}
}]
}
},

],
dataLabels: {
style: {
fontSize: "30px",
fontWeight: "normal"
}
},
type: 'sankey',
name: 'Sankey demo series'
}]
});
一些数据标签被隐藏,因为它们彼此之间太近并且重叠。要显示所有设置:
dataLabels: {
allowOverlap: true,
...
}
