Le plus longs c’est de fixer les problèmes Python …

findfont: Font family 'Helvetica' not found.

Ensuite quelques lignes de code :

import pandas as pd
import calplot
import pylab
from matplotlib import rcParams

df_tem = pd.read_csv('./VeloResume2020-2024-v4.csv', delimiter=";")
df_tem2 = df_tem.groupby([df_tem['date'].dt.date,'activity'])['km'].sum().reset_index().rename(columns={'sum':'km'})
df_tem2 = df_tem2.query('activity=="E-Biking"'
fig = calplot.calplot(df_tem2['km'],
                cmap="BuGn",
                fillcolor="w",
                linecolor="w",
                suptitle_kws=csfont,
                yearlabel_kws={'fontname':'sans-serif'},
                fig_kws=dict(facecolor="w"),
                subplot_kws=dict(facecolor="w"),
                edgecolor="grey")
pylab.savefig('E-Biking.png')
