我想将值为137.55的值分配给谷歌图表中的"数字"类型列,然后绘制它.无论何时我分配浮点数,它都会抛出此异常:

        myVal = parseFloat(Math.round(myVal * 100) / 100).toFixed(2);
        data.addRow([parseInt(i), myVal]);
        myTicks[i] = i;
   }

   formatter.format(data, 1);

  // Create and draw the visualization.
  new google.visualization.AreaChart(document.getElementById('visualization')).
      draw(data, {curveType: "function",
                  width: 700, height: 400,
                  vAxis: {title: 'Throughput'},
                  hAxis: {title: 'Loop', ticks: …
