Basic Pizza Plot (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 will show some examples of how to use mplsoccer to plot pizza-charts.
from urllib.request import urlopen
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/google/fonts/main/apache/roboto/'
'Roboto%5Bwdth,wght%5D.ttf')
font_italic = FontManager('https://raw.githubusercontent.com/google/fonts/main/apache/roboto/'
'Roboto-Italic%5Bwdth,wght%5D.ttf')
font_bold = FontManager('https://raw.githubusercontent.com/google/fonts/main/apache/robotoslab/'
'RobotoSlab%5Bwght%5D.ttf')
Load Image
Load a cropped image of Robert Lewandowski.
URL = "https://raw.githubusercontent.com/andrewRowlinson/mplsoccer-assets/main/lewa_cropped.png"
lewa_cropped = Image.open(urlopen(URL))
Plotting A Simple Pizza-Plot
To plot we need a parameter list and corresponding values list.
# parameter 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"
]
# values for corresponding parameters
# The values are taken from the excellent fbref website (supplied by StatsBomb)
values = [99, 99, 87, 51, 62, 58, 45, 40, 27, 74, 77, 73]
# instantiate PyPizza class
baker = PyPizza(
params=params, # list of parameters
straight_line_color="#000000", # color for straight lines
straight_line_lw=1, # linewidth for straight lines
last_circle_lw=1, # linewidth of last circle
other_circle_lw=1, # linewidth for other circles
other_circle_ls="-." # linestyle for other circles
)
# plot pizza
fig, ax = baker.make_pizza(
values, # list of values
figsize=(8, 8), # adjust figsize according to your need
param_location=110, # where the parameters will be added
kwargs_slices=dict(
facecolor="cornflowerblue", edgecolor="#000000",
zorder=2, linewidth=1
), # values to be used when plotting slices
kwargs_params=dict(
color="#000000", fontsize=12,
fontproperties=font_normal.prop, va="center"
), # values to be used when adding parameter
kwargs_values=dict(
color="#000000", fontsize=12,
fontproperties=font_normal.prop, zorder=3,
bbox=dict(
edgecolor="#000000", facecolor="cornflowerblue",
boxstyle="round,pad=0.2", lw=1
)
) # values to be used when adding parameter-values
)
# add title
fig.text(
0.515, 0.97, "Robert Lewandowski - FC Bayern Munich", size=18,
ha="center", fontproperties=font_bold.prop, color="#000000"
)
# add subtitle
fig.text(
0.515, 0.942,
"Percentile Rank vs Top-Five League Forwards | Season 2020-21",
size=15,
ha="center", fontproperties=font_bold.prop, color="#000000"
)
# add credits
CREDIT_1 = "data: statsbomb viz fbref"
CREDIT_2 = "inspired by: @Worville, @FootballSlices, @somazerofc & @Soumyaj15209314"
fig.text(
0.99, 0.005, f"{CREDIT_1}\n{CREDIT_2}", size=9,
fontproperties=font_italic.prop, color="#000000",
ha="right"
)
plt.show()
Adding Image
One can add image to the pizza plot. The process is like this: first increase the size of the
center circle by using inner_circle_size argument inside PyPizza
and then using add_image method to plot the image at the center.
Hack: You can use Image-Online.co to crop a circle in image online and then use that image for plotting.
# instantiate PyPizza class
baker = PyPizza(
params=params, # list of params
straight_line_color="#000000", # color for straight lines
straight_line_lw=1, # linewidth for straight lines
last_circle_lw=1, # linewidth of last circle
other_circle_lw=1, # linewidth for other circles
other_circle_ls="-.", # linestyle for other circles
inner_circle_size=20 # increase the circle size
)
# plot pizza
fig, ax = baker.make_pizza(
values, # list of values
figsize=(8, 8), # adjust figsize according to your need
param_location=110, # where the parameters will be added
kwargs_slices=dict(
facecolor="cornflowerblue", edgecolor="#000000",
zorder=2, linewidth=1
), # values to be used when plotting slices
kwargs_params=dict(
color="#000000", fontsize=12,
fontproperties=font_normal.prop, va="center"
), # values to be used when adding parameter
kwargs_values=dict(
color="#000000", fontsize=12,
fontproperties=font_normal.prop, zorder=3,
bbox=dict(
edgecolor="#000000", facecolor="cornflowerblue",
boxstyle="round,pad=0.2", lw=1
)
) # values to be used when adding parameter-values
)
# add title
fig.text(
0.515, 0.97, "Robert Lewandowski - FC Bayern Munich", size=18,
ha="center", fontproperties=font_bold.prop, color="#000000"
)
# add subtitle
fig.text(
0.515, 0.942,
"Percentile Rank vs Top-Five League Forwards | Season 2020-21",
size=15,
ha="center", fontproperties=font_bold.prop, color="#000000"
)
# add credits
CREDIT_1 = "data: statsbomb viz fbref"
CREDIT_2 = "inspired by: @Worville, @FootballSlices, @somazerofc & @Soumyaj15209314"
fig.text(
0.99, 0.005, f"{CREDIT_1}\n{CREDIT_2}", size=9,
fontproperties=font_italic.prop, color="#000000",
ha="right"
)
# add image
ax_image = add_image(
lewa_cropped, fig, left=0.4478, bottom=0.4315, width=0.13, height=0.127
) # these values might differ when you are plotting
plt.show()
Adding Colors To Blank Spaces
One can even add colors to blank spaces, color_blank_space
is used for specifying the colors. There are two options that users can use.
If color_blank_space="same" is passed then the slice-color with lower alpha
value will be used to color the blank space. If a list of color is passed to
color_blank_space then those colors will be used. The user can set the alpha
for blank-space using blank_alpha argument.
# instantiate PyPizza class
baker = PyPizza(
params=params, # list of parameters
straight_line_color="#F2F2F2", # color for straight lines
straight_line_lw=1, # linewidth for straight lines
last_circle_lw=0, # linewidth of last circle
other_circle_lw=0, # linewidth for other circles
)
# plot pizza
fig, ax = baker.make_pizza(
values, # list of values
figsize=(8, 8), # adjust figsize according to your need
color_blank_space="same", # use same color to fill blank space
blank_alpha=0.4, # alpha for blank-space colors
kwargs_slices=dict(
facecolor="cornflowerblue", edgecolor="#F2F2F2",
zorder=2, linewidth=1
), # values to be used when plotting slices
kwargs_params=dict(
color="#000000", fontsize=12,
fontproperties=font_normal.prop, va="center"
), # values to be used when adding parameter
kwargs_values=dict(
color="#000000", fontsize=12,
fontproperties=font_normal.prop, zorder=3,
bbox=dict(
edgecolor="#000000", facecolor="cornflowerblue",
boxstyle="round,pad=0.2", lw=1
)
) # values to be used when adding parameter-values
)
# add title
fig.text(
0.515, 0.97, "Robert Lewandowski - FC Bayern Munich", size=18,

)
# add subtitle
fig.text(
0.515, 0.942,
"Percentile Rank vs Top-Five League Forwards | Season 2020-21",
size=15,

Adding Colors To Blank Spaces (2)
Here we will pass a list of color to fill the blank spaces.
# instantiate PyPizza class
baker = PyPizza(
params=params, # list of parameters
straight_line_color="#F2F2F2", # color for straight lines
straight_line_lw=1, # linewidth for straight lines
last_circle_lw=0, # linewidth of last circle
other_circle_lw=0, # linewidth for other circles
)
# plot pizza
fig, ax = baker.make_pizza(
values, # list of values
figsize=(8, 8), # adjust figsize according to your need
color_blank_space=["#C5C5C5"]*len(params), # use same color to fill blank space
blank_alpha=0.4, # alpha for blank-space colors
kwargs_slices=dict(
facecolor="cornflowerblue", edgecolor="#F2F2F2",
zorder=2, linewidth=1
), # values to be used when plotting slices
kwargs_params=dict(
color="#000000", fontsize=12,
fontproperties=font_normal.prop, va="center"
), # values to be used when adding parameter
kwargs_values=dict(
color="#000000", fontsize=12,
fontproperties=font_normal.prop, zorder=3,
bbox=dict(
edgecolor="#000000", facecolor="cornflowerblue",
boxstyle="round,pad=0.2", lw=1
)
) # values to be used when adding parameter-values
)
# add title
fig.text(
0.515, 0.97, "Robert Lewandowski - FC Bayern Munich", size=18,
ha="center", fontproperties=font_bold.prop, color="#000000"
)
# add subtitle
fig.text(
0.515, 0.942,
"Percentile Rank vs Top-Five League Forwards | Season 2020-21",
size=15,
ha="center", fontproperties=font_bold.prop, color="#000000"
)
# add credits
CREDIT_1 = "data: statsbomb viz fbref"
CREDIT_2 = "inspired by: @Worville, @FootballSlices, @somazerofc & @Soumyaj15209314"
fig.text(
0.99, 0.005, f"{CREDIT_1}\n{CREDIT_2}", size=9,
