字典显示了多少块水果和椭圆应该是什么颜色。 我正在查看示例代码,如下所示绘制字典
例如: my_dict {' apples':[20,'#2E9127'],' pears':[3,'#FB9A27'],&# 39;樱桃':[7,'#187429']}
所以这样情节将显示该颜色#20E9127的20个点。
此时键不相关,但value1是计数,v2是十六进制颜色 所以当我制作elipse(graph below or click this link)时,我希望看到20次#2E9127,3次#FB9A27和7次#187429。
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.patches import Ellipse
NUM = len(my_dict) #but dont want total random dots so thinking this is
#sum of value 1 possibly in a loop
#example from matplotlib
# so clearly dont want random np values
ells = [Ellipse(xy=np.random.rand(2) * 10,
width=np.random.rand(), height=np.random.rand(),
angle=np.random.rand() * 360)
for i in range(NUM)]
#ME HAVING A CRACK!
#
ells = [Ellipse(xy=my_dict(2) * 10,
width=np.random.rand(), height=np.random.rand(),
angle=np.random.rand() * 360,facecolor=y)
for i in range(NUM)]
fig, ax = plt.subplots(subplot_kw={'aspect': 'equal'})
for e in ells:
ax.add_artist(e)
e.set_clip_box(ax.bbox)
e.set_alpha(np.random.rand())
e.set_facecolor(np.random.rand(3))
ax.set_xlim(0, 10)
ax.set_ylim(0, 10)
plt.show()
答案 0 :(得分:1)
如果我正确理解了这个问题,你想要绘制尽可能多的椭圆,就像字典中给出的值的总和一样。 (20个苹果,7个樱桃,3个梨)
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.patches import Ellipse
my_dict ={'apples': [20, '#2E9127'], 'pears': [3, '#FB9A27'], 'cherries': [7, 'crimson']}
fig, ax = plt.subplots(subplot_kw={'aspect': 'equal'})
for key, val in my_dict.items():
color = val[1]
for i in range(val[0]):
el = Ellipse(xy=np.random.rand(2) * 10,
width=np.random.rand(), height=np.random.rand(),
angle=np.random.rand() * 360, color=color)
ax.add_artist(el)
ax.set_xlim(0, 10)
ax.set_ylim(0, 10)
plt.show()
我让樱桃红了,能够清楚地看到它们:
