如何构建一个程序，将该数据放入字符串中，我需要使用该字符串来获取频率响应并使用 Matplotlib 绘制数据？数据量将是未知的。对于 y 轴，绘制数据点。对于 x 轴，数字增加 1，[0,1,2,3,4,5,6...n]。如果有更好的实现方法，请详细说明。谢谢你!
最佳答案
使用 numpy 将数据读取到 float 数组中，根据范围 (len(your_array)) 绘制该数据，然后显示该图。
关于python - 使用 matplotlib 在 python 中打开并绘制数据，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19101328/
