我一直在研究一段代码，要求我们读取数据并绘制对数功率图 . 我的日志功率似乎都很好，但是一旦我尝试确定t值（即每个数据点的时间，使用25kHz的给定频率）并使用我的图中的值，我得到Valueerror：x和y必须具有相同的第一维度 .
我想某个地方我丢失了或者在其中一个集合中获得了数据点，但我不知道在哪里 .
import matplotlib.pyplot as plt #importing relevent libraries
import math
import numpy as np
filename = raw_input("Enter filename : ") #requesting file to input
filein = open(filename, "r") #opening requested file
v = [] #empty lists for data
c = [] #v for voltage and c for current
for line in filein.readlines():
if line.startswith("#"): #ignoring comments within data
continue
data = line.split(",") #seperating data
v.append(float(data[0])) #assigning data to lists
c.append(float(data[1]))
vc = []
for i in range(0,len(v)):
vc.append(v[i]*c[i]) #multiplying the two lists together
log = (math.log(math.e)) #addressing the log power
power = [p * (math.log(math.e)) for p in vc] #the log power of v(t)*i(t)
t = [x / 100000.0 for x in range (4, 10 *len(v), 4)] #creating time range and intervals from frequency
filein.close() #closing data file
plt.plot(t, power) #plotting the graph
plt.title("Log Power of Electrical Circuit")
plt.xlabel("t")
plt.ylabel("p(t)")
plt.show()
欢迎任何想法，谢谢
