Matplotlib是Python中的一個庫,它是數字的-NumPy庫的數學擴展。 Pyplot是Matplotlib模塊的基於狀態的接口,該模塊提供了MATLAB-like接口。
matplotlib.pyplot.polar()函數:
matplotlib庫的pyplot模塊中的polar()函數用於繪製極坐標圖。
用法: matplotlib.pyplot.polar(*args, **kwargs)
參數:此方法不接受任何參數。
返回:此方法不返回任何值。
以下示例說明了matplotlib.pyplot中的matplotlib.pyplot.polar()函數:
範例1:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import matplotlib.transforms as mtransforms
import numpy as np
from matplotlib.transforms import offset_copy
xs = np.arange(-2, 2)
ys = np.cos(xs**2)
plt.polar(xs, ys)
plt.title('matplotlib.pyplot.polar() function Example',
fontweight ="bold")
plt.show()
輸出:
範例2:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import matplotlib.transforms as mtransforms
import numpy as np
from matplotlib.transforms import offset_copy
xs = np.arange(8)
ys = np.cos(xs**2)
fig = plt.figure(figsize =(5, 10))
ax = plt.subplot(1, 1, 1)
trans_offset = mtransforms.offset_copy(ax.transData, fig = fig,
y = 6, units ='dots')
for x, y in zip(xs, ys):
plt.polar(x, y, 'go')
plt.text(x, y, '% d, % d' % (int(x), int(y)),
transform = trans_offset,
horizontalalignment ='center',
verticalalignment ='bottom')
plt.title('matplotlib.pyplot.polar() function Example',
fontweight ="bold")
plt.show()
輸出:
