Matplotlib Pie Chart
Python
pythonCopy# -*- coding: utf-8 -*-
import matplotlib.pyplot as plt
x = np.array([15, 25, 30, 40])
label = ["France", "Germany", "Uk", "US"]
plt.pie(x, labels=label)
plt.show()
Syntax
Python
pythonCopymatplotlib.pyplot.pie(
x,
explode=None,
labels=None,
colors=None,
autopct=None,
pctdistance=0.6,
shadow=False,
labeldistance=1.1,
startangle=None,
radius=None,
counterclock=True,
wedgeprops=None,
textprops=None,
center=(0, 0),
frame=False,
hold=None,
data=None,
)
Parameters
| Name | Description |
|---|---|
label |
label text |
fontdict |
label text font dictionary, like family, color, weight and size |
labelpad |
Spacing in points between the label and the x-axis |
Matplotlib Pie Chart in Clockwise Direction
If the argument counterclock is set to be False, then the pie chart will be drawn in clockwise direction.
Python
pythonCopy# -*- coding: utf-8 -*-
import matplotlib.pyplot as plt
x = np.array([15, 25, 30, 40])
label = ["France", "Germany", "Uk", "US"]
plt.pie(x, labels=label, counterclock=False)
plt.show()
Matplotlib Pie Chart With Explode Slice
The explode parameter controls the explode of slices in pie charts. It specifies the fraction of the radius with which offset each wedge.
Python
pythonCopy# -*- coding: utf-8 -*-
import matplotlib.pyplot as plt
x = np.array([15, 25, 30, 40])
label = ["France", "Germany", "Uk", "US"]
plt.pie(x, labels=label, explode=(0.2, 0, 0, 0))
plt.show()
