Matplotlib is the primary library for generating graphs in Python. Most other graphing libraries are wrappers around matplotlib. The matplotlib library is not part of the standard Python library, but it is installed automatically when you install a scientific Python platform such as Anaconda.
Data visualization is one of the key ingredients of data science or data analysis

Hi Matt. Thanks for this useful video!

Could you tell me how to eliminate the gaps on the left and right hand side of the graph? I want my lines in the graph to start from the tip of the y-axis (whatever their intercept) and end where the graph restricts on the right. Thanks

It saved my day🤗
I can't thank you enough🥺

Hey, great tutorial. I'm a newbie and I'm trying an extra step but I'm not finding anything on it. Let's say I have the same example as you with two stocks, but instead of showing absolute values, I want to show their variation as percentages (starting from 0). Any easy way to do that with the library or should I convert everything to fit my needs?

[julioferreira]

Great! how can I put the lasts values (for the two stocks) in the grafic? thanks!

# Yahoo Finance data download method has changed.
# pip install yfinance
# After installing yfinance

import pandas as pd
import yfinance as yf
import matplotlib.pyplot as plt

start_date='2019-01-01'
end_date='2023-01-06'
data = yf.download('AAPL', start_date, end_date)
# data.head()

# plt.plot(data['Close'])
plt.plot(data.Close)

# Anyway, it was helpful. Thank you.

good video but I had a question; Amazon and Google have similar trading prices (in the 1000's) what if I am comparing Amazon to Twitter (trades at 30-40) is there a way to change the y axis so it's in more respective terms or in % change per day?

Hi, Matt. Thank you for posting this. As you may know, this was made before Yahoo discontinued their access to stock data. Could you please make a video explaining how we can use the above graphing information if we pick up the data manually by downloading a CSV file from Yahoo, with the high, low and close, then importing it into Python? And how about a high, low, close graph for a stock? How do we create that? Great job, however.

Hi,
if my data is coming from a csv or an excel file and I need to show/copy these plotted graphs in the same csv/excel, is there a way to do it

[paulatkins]

Hi Matt awesome videos. I'm trying to use python to plot support and resistance lines on an alpaca paper trading account. Have you done a video on this? thanks!

[margaretgonzalez]

Could you tell me how I can ask it to plot from a certain date to another? Btw thanks for the great video

On that line graph, how can we use logo at the end of this line. Suppose if we want to use Facebook and Twitter logo, small size or even how can make a circle and write"FB" or Twitter like this at the end of each multiple line.

[sridhardubasi]

nice flow of explanation, can you show me how to swap the axes ?
