散布図のProjection色々
Projectionパラメータを色々試してみます。
基本
import numpy as np
import matplotlib.pyplot as plt
np.random.seed(20190805)
N = 150
r = 2 * np.random.rand(N)
theta = 2 * np.pi * np.random.rand(N)
area = 200 * r**2
colors = theta
fig = plt.figure()
ax = fig.add_subplot(111)
c = ax.scatter(theta, r, c=colors, s=area, cmap='hsv', alpha=0.75)
aitoff
ax = fig.add_subplot(111, projection='aitoff')
lambert
ax = fig.add_subplot(111, projection='lambert')
mollweide
ax = fig.add_subplot(111, projection='mollweide')
polar
ax = fig.add_subplot(111, projection='polar')
