matplotlib percent label position in pie chart
Solution 1:
You can control the distance of the percents and labels from the center of the pie using pctdistance= and labeldistance=, try this on your code:
plt.pie(sizes, labels=labels, autopct='%1.0f%%', pctdistance=1.1, labeldistance=1.2)
You can also set a radius of the pie using radius= (by default is 1)
