平滑纯图

Question

下面是我的代码，生成一个随机的stock-like datalist，但是输出你根本看不见这些值。有没有办法使图形输出更具可读性？

import random
import plotly.express as px
import pandas as pd


prices = []
days = [day for day in range(365*12)]
spacing = 10

price = random.uniform(0, 884)

for x in range(365*12):
    prices.append(price-random.uniform(0, 5))

df = pd.DataFrame(list(zip(prices, days)), columns =['Stock Price', 'Days'])

fig = px.line(df, x="Days", y="Stock Price")
fig.show()

Answer 1

弄明白了：

import random
import plotly.express as px
import pandas as pd
import numpy as np

prices = []
days = [day for day in range(365*12)]
spacing = 10

price = random.uniform(0, 884)

for x in range(365*12):
  prices.append(price-random.uniform(0, 100))

df = pd.DataFrame(list(zip(prices, days)), columns =['Stock Price', '_'])

fig = px.line(df.rolling(75).sum()/75, x="_", y="Stock Price")
fig.show()


from functools import reduce

def Average(lst):
    return reduce(lambda a, b: a + b, lst) / len(lst)
 
print(round(Average(prices),2))
