How to display actual values instead of percentages on my pie chart using matplotlibs

Question

I want my piechart that I have created using matplotlib to show the actual value rather than just the percentge. Here is my code:

pie_shares= [i for i in mean.values()]
positions = [i for i in mean.keys()]
plt.pie(pie_shares,labels=positions, autopct='%1.1f%%', )
plt.show()

Just remove the "autopct=" part. – KuboMD Dec 14 '18 at 15:29 — KuboMD, Dec 14 '18 at 15:29

If you want to display the actual value of the slices of your pie chart you must provide to the labels those values:

def autopct_format(values):
    def my_format(pct):
        total = sum(values)
        val = int(round(pct*total/100.0))
        return '{v:d}'.format(v=val)
    return my_format
plt.pie(pie_shares, labels = positions, autopct = autopct_format(pie_shares))

In the matplotlib resources, it is mentioned that autopct can be a string format and a function, so, we create a custom function that formats each pct to display the actual value from the percentages used commonly by this feature.

This works but I also need it to show the titles (positions) as well. How could i do this? – jd55 Dec 14 '18 at 15:53

`return '{v:,}'.format(v=val)` for comma separated thousands, ... – Martin Dvorak Jan 08 '20 at 07:16
