为数据点显示错误的工具提示

Question

我有两个 y 轴，问题出在第二个 y 轴：这些点出现在图中的正确位置，但只有当我将鼠标悬停在 x 轴的前两个点上时，才会出现带有相应数据的工具提示.我已将

showLine

属性设置为 false，因为我希望它是散点图。所以我没有传递 x 轴上所有点的数据。这是数据：

[{x: 7, y: 4},
{x: 18, y: 1}]

const data = {
        labels: [] as number[],
        datasets: [
            {
                label: 'Words Per Minute',
                data: [] as number[],
                fill: true,
                backgroundColor: mainColor,
                borderColor: mainColor,
                borderWidth: 3,
                lineTension: 0.4,
                yAxisID: 'y',
            },
            {
                label: 'Incorrect Characters',
                data: [] as any[],
                fill: true,
                borderColor: function (context: any) {
                    const dataPoint = context.dataset.data[context.dataIndex];
                    if (dataPoint && dataPoint.hasOwnProperty('y') && dataPoint.y === 0) {
                        return 'transparent';
                    } else {
                        return errorColor;
                    }
                },
                backgroundColor: function (context: any) {
                    const dataPoint = context.dataset.data[context.dataIndex];
                    if (dataPoint && dataPoint.hasOwnProperty('y') && dataPoint.y === 0) {
                        return 'transparent';
                    } else {
                        return errorColor;
                    }
                },
                borderWidth: 3,
                pointRadius: 4,
                pointHoverRadius: 8,
                showLine: false,
                yAxisID: 'y1',
                pointStyle: 'cross'
            },
        ],
    };

                            else if (index === 0) return 0;
                            else return '';
                        }
                    }
                },
                grid: {
