当运行下面的代码是好的。但我需要 x 轴
中的日期
test['avg'].plot(legend=True,figsize=(12,5))
plt.grid(True)
plt.xlabel('ADX')
plt.ylabel('date')
plt.title('ADX indicator')
plt.gcf().autofmt_xdate()
plt.show()
正确的情节：
但是当我为 x 轴选择 date 时，我的情节很糟糕。代码如下：
df.set_index('date',drop=True, inplace=True)
test['avg'].plot(legend=True,figsize=(12,5))
plt.grid(True)
plt.xlabel('ADX')
plt.ylabel('date')
plt.title('ADX indicator')
plt.gcf().autofmt_xdate()
plt.show()
糟糕的情节：
以及为什么我在 TA-lib 中为 ADX 取 NaN 值
你能帮我解决这个问题吗？
看来确实是源文件的问题。列名称不是制表符分隔的。修复后，绘图工作正常。
NaN问题也是源文件；未计算前几行的平均值。
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
test = pd.read_csv(r"modified_data.dat", sep='\t')
test.set_index('date')
date = test['date']
avg = test['avg']
fig, ax = plt.subplots(figsize=(20,10))
ax.plot(date, avg)
ax.tick_params(rotation=30, width = 2)
plt.xticks(np.arange(0, len(date)+1, 5))
ax.set_xticks
输出如下所示：

当运行下面的代码是好的。但我需要 x 轴
test['avg'].plot(legend=True,figsize=(12,5))
plt.grid(True)
plt.xlabel('ADX')
plt.ylabel('date')
plt.title('ADX indicator')
plt.gcf().autofmt_xdate()
plt.show()
正确的情节：
但是当我为 x 轴选择 date 时，我的情节很糟糕。代码如下：
df.set_index('date',drop=True, inplace=True)
test['avg'].plot(legend=True,figsize=(12,5))
plt.grid(True)
plt.xlabel('ADX')
plt.ylabel('date')
plt.title('ADX indicator')
plt.gcf().autofmt_xdate()
plt.show()
糟糕的情节：
看来确实是源文件的问题。列名称不是制表符分隔的。修复后，绘图工作正常。
NaN问题也是源文件；未计算前几行的平均值。
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
test = pd.read_csv(r"modified_data.dat", sep='\t')
test.set_index('date')
date = test['date']
avg = test['avg']
fig, ax = plt.subplots(figsize=(20,10))
ax.plot(date, avg)
ax.tick_params(rotation=30, width = 2)
plt.xticks(np.arange(0, len(date)+1, 5))
ax.set_xticks
输出如下所示：
