试试这个：（来自：https ://github.com/chartjs/chartjs-plugin-annotation ）

{
    plugins: {
        annotation: {
            annotations: [{
                id: 'a-line-1',
                type: 'line',
                mode: 'horizontal',
                scaleID: 'y-axis-0',
                value: '25',
                borderColor: 'red',
                borderWidth: 2,
            }]
        }
    }
}
