投資有風險，選擇需謹慎。 股票交易數(shù)據(jù)分析可直觀股市走向，對于如何把握股票行情，快速解讀股票交易數(shù)據(jù)有不可替代的作用！

1 數(shù)據(jù)預處理1.1 股票歷史數(shù)據(jù)csv文件讀取

import pandas as pdimport csv

df = pd.read_csv('/home/kesci/input/maotai4154/maotai.csv')

1.2 關鍵數(shù)據(jù)——在csv文件中選擇性提取“列”

df_high_low = df[[’date’,’high’,’low’]]

1.3 數(shù)據(jù)類型轉換

df_high_low_array = np.array(df_high_low)df_high_low_list =df_high_low_array.tolist()

1.4 數(shù)據(jù)按列提取并累加性存入列表

price_dates, heigh_prices, low_prices = [], [], []for content in zip(df_high_low_list): price_date = content[0][0] heigh_price = content[0][1] low_price = content[0][2] price_dates.append(price_date) heigh_prices.append(heigh_price) low_prices.append(low_price)

2 pyecharts實現(xiàn)數(shù)據(jù)可視化2.1 導入庫

import pyecharts.options as optsfrom pyecharts.charts import Line2.2 初始化畫布

Line(init_opts=opts.InitOpts(width='1200px', height='600px'))2.3 根據(jù)需要傳入關鍵性數(shù)據(jù)并畫圖

.add_yaxis(series_name='最低價',y_axis=low_prices,markpoint_opts=opts.MarkPointOpts( data=[opts.MarkPointItem(value=-2, name='周最低', x=1, y=-1.5)]),markline_opts=opts.MarkLineOpts( data=[opts.MarkLineItem(type_='average', name='平均值'),opts.MarkLineItem(symbol='none', x='90%', y='max'),opts.MarkLineItem(symbol='circle', type_='max', name='最高點'), ]), )

tooltip_opts=opts.TooltipOpts(trigger='axis'),toolbox_opts=opts.ToolboxOpts(is_show=True),xaxis_opts=opts.AxisOpts(type_='category', boundary_gap=True)2.4 將生成的文件形成HTML代碼并下載

.render('HTML名字填這里.html')
