如何通过给出X Y Z轴在Plotly中绘制3D表面图

Question

我有如下数据表

X       Y       Z
12.22   6.38    9.93
8.97    10.37   8.66
8.8     7.6     10.26
10.96   10.18   8.99
8.14    9.77    11.3
17.79   12.99   11.05
11.04   12.93   11.15
11.97   9.79    10.73
10.29   10.2    10.17
9.74    4.58    9.32
10.32   10.47   10.24
9.15    13.59   9.66
8.1     5.85    9.23
6.55    10.58   9.69
18.78   8.29    9.39

然后我创建了一个网格，水平X，垂直Z，在单元格中填充Y值。

选择数据并选择3D曲面图后，它生成了如下图：

我尝试了下面的示例，其中Z中的第一个数字为空：

  var data = [
{
  z: [[,6.55,8.1,8.14,  8.8,8.97,9.15,9.74,10.29,10.32,10.96,11.04,11.97,12.22,17.79,18.78],
    [8.66,0,0,0,0,10.47,0,0,0,0,0,0,0,0,0,0],
    [8.99,0,0,0,0,0,0,0,0,0,10.18,0,0,0,0,0],
    [9.23,0,5.85,0,0,0,0,0,0,0,0,0,0,0,0,0],
    [9.32,0,0,0,0,0,0,4.58,0,0,0,0,0,0,0,0],
    [9.39,0,0,0,0,0,0,0,0,0,0,0,0,0,0,8.29],
    [9.66,0,0,0,0,0,13.59,0,0,0,0,0,0,0,0,0],
    [9.69,10.58,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
    [9.93,0,0,0,0,0,0,0,0,0,0,0,0,6.38,0,0],
    [10.17,0,0,0,0,0,0,0,10.2,0,0,0,0,0,0,0],
    [10.24,0,0,0,0,0,0,0,0, 10.47,0,0,0,0,0,0],
    [10.26,0,0,0,7.6,0,0,0,0,0,0,0,0,0,0,0],
    [10.73,0,0,0,0,0,0,0,0,0,0,0,9.79,0,0,0],
    [11.05,0,0,0,0,0,0,0,0,0,0,0,0,0,12.99,0],
    [11.15,0,0,0,0,0,0,0,0,0,0,12.93,0,0,0,0],
    [11.3,0,0,9.77,0,0,0,0,0,0,0,0,0,0,0,0]],
    type: 'surface'
}];
var layout = {
    title: 'Mt Bruno Elevation',

    autosize: false,
    width: 700,
    height: 700,
    margin: {
      l: 130,
      r: 100,
      b: 130,
      t: 180,
    }
  };
 Plotly.newPlot('example', data, layout);

它生成了一个图表，如下所示：

我不知道生成的Z数据是否错误。谁能告诉我我做错了哪一部分？或建议我生成类似于Excel图表的3d曲面的方法
