Question

我有来自加速度计（x，y，z）的一串数据（在文本文件“XXX XXX XXX”中看起来像这样，我试图读取它并转换为带有三个子图数据的折线图。我正在调整朋友的一些代码来做这个，但我不确定这些错误是从哪里来的。显然是初学程序员。非常感谢。

错误：带有基数10的int（）的文字无效

import os
import numpy as npy
import matplotlib.pyplot as plt
global y0,y1,y2
increment_size = 8000
datasample_size = 16000

from os.path import join

infile = join(filepath, 'data.txt')
infile = open(infile,"r")

# plt.close()

Answer 1

您可能尝试使用float()解析int()。

如果您需要处理空值，请尝试int(s or 0)

Answer 2

有一个numpy功能可以为你完成所有这些功能。我很难在不知道你的数据文件格式的情况下进行测试（如果你粘贴在'data.txt'的前几行中会有所帮助）

from os import path

import numpy as npy
import matplotlib.pyplot as plt

increment_size  =  8000
datasample_size = 16000

filepath = "C:\\Users\\Riley\\Documents\\Programming\\"
infile = path.join(filepath, 'data.txt')

# This line replaces all the file reading lines:
y0, y1, y2 = npy.genfromtxt(infile, unpack=True)

totaldata = len(y0)
print(totaldata)

low = 0
high = datasample_size

while low < totaldata:
    ...

可能也可以更简单地完成绘图，但我不确定我理解你为什么要逐节绘制它。
