根据您提供的代码，我猜测您的问题可能是每次迭代时没有清空绘图区域，导致新的图形叠加在之前的图形上。您可以在每次迭代之前调用 plt.clf() 方法，这将清除当前绘图区域中的所有内容，以便您可以从头开始绘制新的图形。修改后的代码如下：

import os
import numpy as np
import pandas as pd
from PIL import Image
from matplotlib import pyplot as plt

plt.figure(figsize=(4, 2), dpi=50, frameon=False)
ax = plt.axes([0, 0, 1, 1])
grey = plt.get_cmap('Greys')
seismic = plt.get_cmap('bwr')

datapath = "G:/功图excel/0"
conds = os.listdir(datapath)
for cond in conds:
    data = pd.read_csv("G:/功图excel/0/" + cond)
    os.mkdir(r"G:/功图/0/" + cond[:-4])

    data = np.array(data)
    data = data.tolist()

    n = 0
    for i in data:
        if np.isnan(i).any():
            continue

        WY = i[0:200]
        ZH = i[200:400]

        plt.plot(WY[0: 100], ZH[0: 100], color=seismic(5 / 5.0), lw=3)
        plt.plot(WY[100: 200], ZH[100: 200], color=seismic(0 / 5.0), lw=3)
        plt.xticks([])
        plt.yticks([])
        ax.spines['right'].set_visible(False)
        ax.spines['top'].set_visible(False)
        ax.spines['left'].set_visible(False)
        ax.spines['bottom'].set_visible(False)

        Y_ALL = []
        Y_ALL.extend(list(map(float, ZH)))
        Y_MAX, Y_MIN = np.max(Y_ALL), np.min(Y_ALL)
        ax.set_ylim(np.min([0, Y_MIN - (Y_MAX - Y_MIN) * 0.1]), Y_MAX + (Y_MAX - Y_MIN) * 0.1)

        plt.savefig("G:/功图/0/" + cond[:-4] + '/' + str(n), dpi=50)
        plt.clf()  # 清空绘图区域
        n = n + 1

希望这可以解决您的问题。
