Python – displaying numbers with legend on pie chart – Tkinter, Pyplot, Matplotlib

I am developing a application using Tkinter for the interface, and then using pyplot from matplotlib to create a pie chart.

I have successfuly been able to display the data on a pie chart without a legend, such that the percentages are shown. Below is the relevant source code extract.

labels = ["Oranges", "Bananas", "Apples", "Kiwis", "Grapes", "Pears"]
values = [0.1, 0.4, 0.1, 0.2, 0.1, 0.1]

 # now to get the total number of failed in each section
actualFigure = plt.figure(figsize = (8,8))
actualFigure.suptitle("Fruit Stats", fontsize = 22)

#explode=(0, 0.05, 0, 0)
# as explode needs to contain numerical values for each "slice" of the pie chart (i.e. every group needs to have an associated explode value)
explode = list()
for k in labels:
    explode.append(0.1)

pie= plt.pie(values, labels=labels, explode = explode, shadow=True)

canvas = FigureCanvasTkAgg(actualFigure, self)
canvas.get_tk_widget().pack()
canvas.show()

I have also been able to display the same pie chart, with the legend but without the numerical values:

labels = ["Oranges", "Bananas", "Apples", "Kiwis", "Grapes", "Pears"]
values = [0.1, 0.4, 0.1, 0.2, 0.1, 0.1]

 # now to get the total number of failed in each section
actualFigure = plt.figure(figsize = (10,10))
actualFigure.suptitle("Fruit Stats", fontsize = 22)

#explode=(0, 0.05, 0, 0)
# as explode needs to contain numerical values for each "slice" of the pie chart (i.e. every group needs to have an associated explode value)
explode = list()
for k in labels:
    explode.append(0.1)

pie, text= plt.pie(values, labels=labels, explode = explode, shadow=True)
plt.legend(pie, labels, loc = "upper corner")

canvas = FigureCanvasTkAgg(actualFigure, self)
canvas.get_tk_widget().pack()
canvas.show()

However, I am unable to display both the legend and the numerical values on the pie chart, at the same time.

If I add "autopct='%1.1f%%'" field into the pie, text = plt.pie(…) line I get the following error:

"pie, text= plt.pie(values, labels=labels, explode = explode, autopct='%1.1f%%', shadow=True)
ValueError: too many values to unpack"
