張郎生活的筆記

承接之前抓下來的歷史資料, 咱們今天來畫一畫K線圖

不過用的是plotly, 首先當然還是要pip install plotly

import pandas as pd
import plotly.plotly as py
import plotly.offline as pyoff
import plotly.graph_objs as go

df = pd.read_csv(r'c:\0050.tw.csv')

trace = go.Ohlc(x=df['Date'],
                open=df['Open'],
                high=df['High'],
                low=df['Low'],
                close=df['Close'])
data = [trace]

pyoff.plot(data)

plotly如果要線上畫圖, 必須要註冊一個帳號

所以我們用pyoff來離線畫圖

網路上都說畫出來的圖比較精美, 大家覺得呢?
