Drawing of Matplotlib series-pyplot pie chart

Pyplot use Plt.pie () to draw a pie chart

Import Matplotlib.pyplot as plt

labels = ' frogs ', ' hogs ', ' Dogs ', ' Logs '
sizes = [15,30,45,10]
explode = ( 0,0.1,0,0) #0 1 means to highlight the Hogs piece
plt.pie (sizes,explode=explode,labels=labels,autopct= '%1.1f%% ', Shadow=false, startangle=90)
#startangle表示饼图的起始角度

plt.show ()

Run Result:

So how do you make the pie chart appear as a pie chart with a long width equal to just one line of code?

Import Matplotlib.pyplot as plt

labels = ' frogs ', ' hogs ', ' Dogs ', ' Logs '
sizes = [15,30,45,10]
explode = ( 0,0.1,0,0) #0 1 means to highlight the Hogs piece
plt.pie (sizes,explode=explode,labels=labels,autopct= '%1.1f%% ', Shadow=false, startangle=90) #startangle表示饼图的起始角度

plt.axis (' equal ')  #加入这行代码即可.
Plt.show ()

Run Result:
