我有一个名为'data.rei'的数据集，另一个叫做'gages.txt'。 'data.rei'包含数据，'gages.txt'包含我想要与数据链接的位置ID信息和日期/时间。我想绘制这些，每个位置1个图表，包括x轴上的日期和y轴上的测量和建模值。
data.rei的格式如下：

到目前为止，这是我的脚本：
import numpy as np
import matplotlib.pyplot as plt
data = np.genfromtxt('elm3_1-4 - Copy.rei', dtype=None, names=True, skip_header=6)
gages = np.genfromtxt('elmph3_dev_gages_28may2013.txt', dtype=None, names=True)
font = {'size' : 10,}
#-----Dev BFs__________________________________
#plt.rc('axes', color_cycle=['r'])
for gages['gage'] in gages:
if gages['pestID'] == data['Name']:
plt.scatter(gages['date'], data['Measured'],gages['date'], data['Modelled'])
plt.legend('Measured','Modelled')
#plt.plot([0,4000],[0,4000])
plt.xlabel('Measured (ft)', fontdict=font)
plt.ylabel('Modelled (ft)', fontdict=font)
plt.title.gages(['gage'], fontdict=font)
#plt.xlim(1000,4000)
#plt.ylim(-2000,4000)
plt.show()
但是，我收到错误消息：

这似乎有效
