Comparison Pizza (Percentiles)
Author: slothfulwave612
mplsoccer,py_pizzamodule 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 for comparing two players.
import matplotlib.pyplot as plt
from highlight_text import fig_text
from mplsoccer import PyPizza, 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')
Comparison Chart
To plot comparison chart one have to pass list of values to compare_values argument.
# parameter and values list
# The values are taken from the excellent fbref website (supplied by StatsBomb)
params = [
"Non-Penalty Goals", "npxG", "npxG per Shot", "xA",
"Open Play\nShot Creating Actions", "\nPenalty Area\nEntries",
"Progressive Passes", "Progressive Carries", "Successful Dribbles",
"\nTouches\nper Turnover", "pAdj\nPress Regains", "Aerials Won"
]
values = [99, 99, 87, 51, 62, 58, 45, 40, 27, 74, 77, 73] # for Robert Lewandowski
values_2 = [83, 75, 55, 62, 72, 92, 92, 79, 64, 92, 68, 31] # for Mohamed Salah
# instantiate PyPizza class
baker = PyPizza(

# plot pizza

Adjust Overlapping Values
To adjust overlapping values one can use adjust_texts() method.
The user have to pass params_offset list
which will contain bool values denoting which parameter’s text is to be adjusted,
an offset value denoting how much adjustment will be made,
and if the user wants to adjust the comparison-text then can pass
adj_comp_values=True to the adjust_texts() method. Below is an example code.
# parameter and values list
params = [
"Non-Penalty Goals", "npxG", "npxG per Shot", "xA",
"Open Play\nShot Creating Actions", "\nPenalty Area\nEntries",
"Progressive Passes", "Progressive Carries", "Successful Dribbles",
"\nTouches\nper Turnover", "pAdj\nPress Regains", "Aerials Won"
]
# dummy values
values = [15, 7, 57, 86, 63, 51, 11, 32, 85, 69, 90, 54] # for Player 1
values_2 = [31, 41, 43, 42, 47, 24, 60, 60, 28, 70, 92, 64] # for Player 2
# pass True in that parameter-index whose values are to be adjusted
# here True values are passed for "\nTouches\nper Turnover" and "pAdj\nPress Regains" params
params_offset = [
False, False, False, False, False, False,
False, False, False, True, True, False
]
