我在一个项目上使用 ChartJS 来绘制一个折线图，它有 5 个不同的线/标签。

默认情况下，ChartJS 会一次性绘制所有线条，您可以单击它们的每个标签以停用它们。我想要相反的，但我还没有找到办法做到这一点。

        pointHoverBorderColor: "#103e58",
        data: [4.7000, 4.5600, 4.8110, 4.9000, 4.9890, 4.8292, 4.68690]
      },
        {
          label: 'GBP',
          backgroundColor: "rgba(88, 234, 245, 0.4)",
          strokeColor: "#76e5f2",
