我使用chartjs创建了图形。它工作正常，唯一的问题是它在每个点上都显示了数据标签（数字）。我想隐藏它们，但找不到方法。谁能帮我解决这个问题？我尝试将pointRadius设置为0，但是它没有执行我想要的操作。

另外，如果我无法隐藏它们，是否可以更改它们的颜色？

const ctx = document.getElementById('timelineChart');

        const chartColors = {
            red: '#C82846',
            green: '#7DC36E',
            blue: '#249FBA',
            darkblue: '#249FBA'
        };

            plugins: [new BandsPlugin()],
