# 点样式

¥Point Style

此示例演示如何使用工具提示中的数据集点样式而不是矩形来标识每个数据集。

¥This sample shows how to use the dataset point style in the tooltip instead of a rectangle to identify each dataset.

const config = {
  type: 'line',
  data: data,
  options: {
    interaction: {
      mode: 'index',
    },
    plugins: {
      title: {
        display: true,
        text: (ctx) => 'Tooltip point style: ' + ctx.chart.options.plugins.tooltip.usePointStyle,
      },
      tooltip: {
        usePointStyle: true,
      }
    }
  }
};
