如何在python中绘制烛台 [英] how to plot candlesticks in python

问题描述

我正在尝试用烛台创建一个简单的情节。为此，我从Yahoo获得数据并使用功能Candlestick2_ohlc对其进行绘制。目标是使用导出图像为jpg文件。

I´m trying to create a simple plot with candlesticks. For that I get the data from Yahoo and plot it using the function candlestick2_ohlc. The goal is to export the image in a jpg file using.

这是我正在使用的代码：

This is the code what I´m using:

from pandas_datareader import data
import matplotlib.pyplot as plt
from mpl_finance import candlestick2_ohlc
import matplotlib.dates as mdates
import fix_yahoo_finance as yf
import datetime

start = datetime.date(2018, 1, 1)
end = datetime.date.today()

aapl = yf.download("AAPL",start,end) 
aapl.reset_index(inplace=True)

aapl['Date'] = aapl.index.map(mdates.date2num)

fig, ax = plt.subplots()
plt.xlabel("Date")
plt.ylabel("Price")

candlestick2_ohlc(ax, aapl.Open, aapl.High, aapl.Low, aapl.Close, width=1, colorup='g')
plt.savefig('my_figure.png')
plt.show()

我的第一个问题是：还有另一种简单的方法吗？您能给我一个处理财务数据的例子吗？我通常在R中使用Quantmod。

My first question is: there is another simple way to do it? Could you please give me an example to work with finance data? I usually work with quantmod in R.

第二个问题是：在我的示例中，X轴中没有日期。如何在X轴上显示带有日期的图？我应该将Date转换为AX格式，但是我不知道这样做的简单方法。

The second question is: In my example, there is no Date in the X axi. What can I do to show the plot with Dates in the X axi? I should transform the Date into a AX format but I don't know a simple way to do it.

谢谢

推荐答案

首先，您需要使用以下命令安装 plotly 软件包：

First you need to install the plotly package using:

pip install plotly

然后，您可以绘制蜡烛图就像下面的代码一样简单：

Then, you can plot the candle plots as easy as the following code:

import plotly.graph_objects as go

import pandas as pd
from datetime import datetime

df = pd.read_csv('your_file_address')

fig = go.Figure(data=[go.Candlestick(x=df['name_of_time_column'],
                open=df['name_of_open_column'],
                high=df['name_of_high_column'],
                low=df['name_of_low_column'],
                close=df['name_of_close_column'])])

fig.show()
