Different Scales Pizza

• Author: slothfulwave612

• mplsoccer, py_pizza module helps one to plot pizza charts in a few lines of code.

• The design idea is inspired by Tom Worville, Football Slices and Soma Zero FC

• We have re-written Soumyajit Bose’s pizza chart code to enable greater customisation.

Here we plot a pizza chart where each parameters has a different maximum and minimum value.

import matplotlib.pyplot as plt
from PIL import Image

from mplsoccer import PyPizza, add_image, FontManager

Load some fonts

We will use mplsoccer’s FontManager to load some fonts from Google Fonts. We borrowed the FontManager from the excellent ridge_map library.

font_normal = FontManager('https://raw.githubusercontent.com/googlefonts/roboto/main/'
                          'src/hinted/Roboto-Regular.ttf')
font_italic = FontManager('https://raw.githubusercontent.com/googlefonts/roboto/main/'
                          'src/hinted/Roboto-Italic.ttf')
font_bold = FontManager('https://raw.githubusercontent.com/google/fonts/main/apache/robotoslab/'
                        'RobotoSlab[wght].ttf')

Load Image

Load a cropped image of Alexia Putellas.

URL = "https://raw.githubusercontent.com/andrewRowlinson/mplsoccer-assets/main/putellas_cropped.png"
putellas_cropped = Image.open(urlopen(URL))

Slices With Different Scales

Let’s say you want to plot values for parameters with different range, e.g. for pass % parameter you have lower limit as 72 and upper limit as 92, for npxG you have lower limit as 0.05 and upper limit as 0.25 so on. In order to plot parameter and values like this see below example. We will pass min-range-value and max-range-value for each parameter.

# parameter and value list
# The values are taken from the excellent fbref website (supplied by StatsBomb)
params = [
    "Passing %", "Deep Progression", "xG Assisted", "xG Buildup",
    "Successful Dribbles", "Fouls Won", "Turnovers", "Pressure Regains",
    "pAdj Tackles", "pAdj Interceptions"
]
values = [82, 9.94, 0.22, 1.58, 1.74, 1.97, 2.43, 2.81, 3.04, 0.92]

# minimum range value and maximum range value for parameters
min_range = [74, 3.3, 0.03, 0.28, 0.4, 0.7, 2.6, 2.4, 1.1, 0.7]
max_range = [90, 9.7, 0.20, 0.89, 2.1, 2.7, 0.4, 5.1, 3.7, 2.5]

# instantiate PyPizza class
baker = PyPizza(
    params=params,
    min_range=min_range,        # min range values
    max_range=max_range,        # max range values
    background_color="#222222", straight_line_color="#000000",
    last_circle_color="#000000", last_circle_lw=2.5, straight_line_lw=1,
    other_circle_lw=0, other_circle_color="#000000", inner_circle_size=20,
)

# plot pizza
fig, ax = baker.make_pizza(
    values,                     # list of values

            boxstyle="round,pad=0.2", lw=1
        )
    )                           # values to be used when adding parameter-values
)
