结果应该看起来：

1st，我从 .csv 文件（c7.csv）中读取数据

with open('c7.csv', newline='') as f:
  reader = csv.reader(f)
  data = list(reader)

2，我从输入数据中找到开始和结束的地方

cnt_start = 0;
while(data[cnt_start][0] != 'Scan Start'):
  cnt_start+=1

cnt_end = 0;
while(data[cnt_end][0] != 'Scan End'):
  cnt_end+=1

3rd，我从输入数据中的“扫描开始”到“扫描结束”的开始和结束位置抓取数据

vals = []
for i in range(cnt_start +1 , cnt_end):
  vals.append(data[i])

并删除 str '2d statistics'

vals[0].pop(0) 

4、由于数据是字符串类型，所以我将其转换为浮点类型

for i in vals:
  for j in i:
    j = float(j)

5、我从以前的数据中提取行比例和列比例

column_vals = []
column_vals = vals.pop(0)

row_vals = []
for i in vals:
  row_vals.append(i.pop(0))

最后，我显示绘图所需数据的数据输出

print(column_vals) # x scale
print(row_vals) # y scale
print(vals) # z data

上面的所有代码都在这里 （如果需要的包已经安装，可以执行此代码）

所需数据似乎已准备就绪。

我该如何做下一步（绘制 2D 并添加比例 x_data、y_data）？
