Visualizing Stocks

Understanding stocks can be hard but In this post, we will be visualizing stocks with the help of Plotly(a visualization Library). As we all know Python is really powerful when it comes to handling data. Therefore we will be using modules such as Pandas to handle our CSV files and Plotly to visualize our data.

In order to begin we need to install a few libraries

• Install Anaconda Distribution. (This contains all data science related packages/modules) Installion Link.
• Install Plotly (This is not included in Anaconda) pip install plotly.

If you don't want to install Anaconda. You can install the packages you need by following these instructions.

• Install Pandas pip install pandas.
• Install Jupyter Notebook python3 -m pip install jupyter.
• Install Plotly pip install plotly.

Lets Begin

• First, let start jupyter notebook by running the following command jupyter-notebook.
• Now we have the jupyter-notebook running. We will be importing libraries.

import pandas as pd 
# importing Plotly
import plotly.plotly
import plotly.graph_objs as go

• Turning on offline mode for Plotly

plotly.offline.init_notebook_mode(connected=True)

• Lets download stocks data (It can be found on Yahoo Finance Search for your favourite stock). I will be using AAPL.

• Now we will be reading stocks csv using pandas.

# read_csv allows us to read csv files
data = pd.read_csv('AAPL.csv')
# few pandas operations.

#This will display first few cells of the CSV files we can always specify how many cells we need by passing a number within those parenthesis data.head(10)
data.head()

# This will tell how many rows and columns are there in our CSV file.
data.shape

# This will describe our data by giving us information like mean, max, min, std and etc
data.describe()

• Selecting specific columns using pandas to plot them

# Selecting a specific column from csv file. Note brackets should contain exact name from the csv file.
dates = data['Date']
high = data['High']

• Plotting the data using Plotly

plotly.offline.iplot({
    "data": [go.Scatter(x=dates ,y=high)],
    "layout": go.Layout(title="AAPL Stocks")
})

Output

And now you have the stocks data represented using Line Graph.
