anaconda下matplotlib画散点图、柱形图、折线图、饼图

import matplotlib.pyplot as plt
year = (1950, 1970, 1990, 2010)
pop = (2.519, 3.692, 5.263, 6.972)
plt.fill_between(year,pop,0,color='green')# 折线图
# plt.plot(year, pop)
# 散点图
# plt.scatter(year, pop)
# values = np.linspace(0, 6, 10)
values = [0, 0.6, 1.4, 1.6, 2.2, 2.5, 2.6, 3.2, 3.5, 3.9, 4.2,6]
# 柱形图
# plt.hist(values,bins=3)
plt.xlabel("x")
plt.ylabel('y')
plt.title("title")
# y轴刻度
plt.yticks([0, 2, 4, 6, 8, 10])
plt.show()

xticks,yticks是横竖轴刻度

plt.show()
