matplotlib.pyplot 画图–x轴坐标未展示完全解决办法

背景案例：可视化展示两个骰子点数相乘的结果

die.py

from random import randintclass Die():def __init__(self,num_sides=6):self.num_sides = num_sidesdef roll(self):return randint(1,self.num_sides)

die_visual.py

from die import Diefrom matplotlib import pyplot as pltdie_1 = Die()die_2 = Die()results = []for roll_num in range(1000):result = die_1.roll() * die_2.roll()results.append(result)frequences = []max_result = die_1.num_sides * die_2.num_sidesfor value in range(1,max_result+1):frequence = results.count(value)frequences.append(frequence)# 未转换前# plt.bar(range(1,max_result+1),frequences)# plt.show()# 转换后x = [str(i) for i in range(1,max_result+1)]plt.bar(x,frequences)plt.xticks(rotation = 45)plt.show()

解决方法：

把x轴int类型转换为字符串类型再放入列表中。
