nfl-tracks 1.1.0

Python library written on top of matplotlib library for customizable nfl charts

NFL Play Visualizer

This Python script provides tools for visualizing NFL play data on a football field. Using matplotlib, it creates static snapshots and animated plays of NFL games based on tracking data.

Requirements

• Python 3.x
• pandas
• matplotlib

To install the dependencies:

pip install nfl_tracks

After successfully installing the nfl_tracks package, import it in the file using the code below:

# Import nfl_tracks
from nfl import visuals

Overview

The script contains three main functions:

1. field: Sets up the visual representation of a football field.
2. snap: Creates a static snapshot of a specific play frame.
3. play_game: Animates a play, showing player movements across frames.

Individual functions are listed below.

---

field()

This function sets up the football field with customizable features, such as yard numbers, touchdown markings, and a highlighted 50-yard line.

visuals.field(yard_numbers, touchdown_markings, fifty_yard, fig_size)

Parameters:

• yard_numbers (bool): Whether to display yard numbers. Default is True.
• touchdown_markings (bool): Whether to display touchdown markings. Default is True.
• fifty_yard (bool): Whether to highlight the fifty-yard line. Default is False.
• fig_size (tuple): The size of the figure in inches. Default is (12, 6.33).

Returns:

• fig (matplotlib.figure.Figure): The figure object containing the field.
• ax (matplotlib.axes._subplots.AxesSubplot): The axis object representing the field.

Example Usage:

fig, ax = visuals.field(yard_numbers=True, touchdown_markings=True)

---

snap()

Creates a static snapshot of a specific frame in a play. The snapshot includes player positions and can be customized with field features.

snap(data, gameId, playId, frameId, yard_numbers, touchdown_markings, fifty_yard, fig_size)

Parameters:

• data (pd.DataFrame): The DataFrame containing play data.
• gameId (int): The unique ID of the game.
• playId (int): The unique ID of the play.
• frameId (int): The frame ID of the play.
• yard_numbers (bool): Whether to display yard numbers. Default is True.
• touchdown_markings (bool): Whether to display touchdown markings. Default is True.
• fifty_yard (bool): Whether to highlight the fifty-yard line. Default is False.
• fig_size (tuple): The size of the figure in inches. Default is (12, 6.33).

Returns:

• fig (matplotlib.figure.Figure): The figure object.
• ax (matplotlib.axes._subplots.AxesSubplot): The axis object.

Example Usage:

fig, ax = visuals.snap(data, gameId=2019090800, playId=75, frameId=10)

---

play_game()

Animates an entire play, showing player positions and movements frame by frame. The animation can be saved as a GIF.

play_game(data, gameId, playId, yard_numbers, touchdown_markings, fifty_yard, fig_size, save, loop, **kwargs)

Parameters:

• data (pd.DataFrame): The DataFrame containing play data.
• gameId (int): The unique ID of the game.
• playId (int): The unique ID of the play.
• yard_numbers (bool): Whether to display yard numbers. Default is True.
• touchdown_markings (bool): Whether to display touchdown markings. Default is True.
• fifty_yard (bool): Whether to highlight the fifty-yard line. Default is False.
• fig_size (tuple): The size of the figure in inches. Default is (12, 6.33).
• save (bool): Whether to save the animation as a GIF. Default is False.
• loop (bool): Whether to loop the animation. Default is False.
• **kwargs: Additional keyword arguments for save_params in case saving as a GIF, such as fps and bitrate.

Returns:

• fig (matplotlib.figure.Figure): The figure object.
• ax (matplotlib.axes._subplots.AxesSubplot): The axis object.
• ani (matplotlib.animation.FuncAnimation): The animation object.

Example Usage:

fig, ax, ani = visuals.play_game(data, gameId=2019090800, playId=75, save=True, loop=True)

---

Example of Full Usage:

import pandas as pd
from nfl import visuals

# Load your data into a pandas DataFrame
data = pd.read_csv("week_1.csv")

# Create a field visualization
fig, ax = visuals.field(yard_numbers=True, touchdown_markings=True, fifty_yard=False, fig_size=(12, 6.33))

# Snap a specific frame of a play
fig, ax = visuals.snap(data, gameId=2019090800, playId=75, frameId=10, yard_numbers=True, touchdown_markings=True, fifty_yard=False, fig_size=(12, 6.33))

# Animate a full play and save as GIF
fig, ax, ani = visuals.play_game(data, gameId=2019090800, playId=75, yard_numbers=True, touchdown_markings=True, fifty_yard=False, fig_size=(12, 6.33), save=True, loop=False)
