chartjs放大到错误的行

我以前试过所以我知道这是可能的。我使用chartjs来做几件事：放大和缩小，向左、向右、向上和向下平移，选择图表上的矩形区域并缩放到该区域（使用拖动实现）。无论我在Y轴上平移还是放大或缩小，图表每次都会放大到底部行。当我在按住CTRL键后用鼠标选择一个矩形区域时，图表每次也会缩放到底行。我过去也可以在平移Y轴时上下平移，但这也会放大到图表的底线。我做错了什么？

我可能错了，但根据我的经验，Chartjs并不真正支持字符串作为Y轴值。您可以做的是在呈现图表时输入数值并使用回调函数更改它们。

const getColor = function (context) {
      const {chart, datasetIndex, dataIndex} = context;
      const dataset =  chart.data.datasets[datasetIndex];
      const data = dataset.data[dataIndex];
      
      if (data == undefined)
        return 'rgba(255, 255, 255, 255)';
      else
        return data.backgroundColor;
    }

    const yLabels = ["Test 1", "Test 2", "Test 3", "Test 4", "Test 5", "Test 6", "Test 7", "Test 8", "Test 9", "Test 10"];

    // config 
    const config = {
        type: 'bar',
        data: {
            datasets: [{
                backgroundColor: getColor,
                borderColor: getColor,
                //barPercentage: 1,
