将列表添加到 Matplotlib

Question

我正在做一个随机生成的世界，我从基本图形开始尝试与柏林噪声类似。我做了所有事情，我写的最后一件事（重要的一件事）确实有效。

import math

import random

import matplotlib.pyplot as plt

print('ur seed')

a = input()

seed = int(a)

b = (math.cos(seed) * 100)

c = round(b)

# print(c)

for i in range(10):

   z = (random.randint(-1, 2))

   change = (z + c)

   gener = []

   gener.append(change)

   time = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

   #print(gener)

   #print(change)

   plt.ylabel('generated')

   plt.xlabel('time')

   #Here I wanna add them to the graph and it is Erroring a lot

   plt.scatter(time, gener)

   plt.title('graph')

   plt.show()

Answer 1

问题是您设置gener为[]循环内而不是循环外。另外，您也不需要time循环内的变量。改变for i in range(10):    z = (random.randint(-1, 2))    change = (z + c)    gener = []    gener.append(change)    time = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]到gener = []for i in range(10):    z = (random.randint(-1, 2))    change = (z + c)    gener.append(change)time = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
