  google.load('visualization', '1', {packages: ['corechart']});

  function drawVisualization() {
    // Create and populate the data table.

而不是'smoothLine':true/false你应该使用curveType:'function'/'none'.

此外，您对该系列的索引不正确 - 该系列的索引为零，但您的depth列不计入此索引，因此该mud weight系列实际上是索引 4。

这是应该替换您的更新代码ac.draw(data, {...})：

ac.draw(data, {
  title : 'pore pressure and fracture pressure',
  width: 600,
  height: 400,
  vAxis: {title: "Cups",direction:-1},
  hAxis: {title: "Month"},
  orientation: 'vertical',
  seriesType: "line",
  curveType: 'function',
  series: {4: {curveType: 'none'}}
});
