matplotlib模块
matplotlib模块官方文档
matplotlib是一个绘图库,它可以创建常用的统计图,包括条形图、箱形图、折线图等
条形图
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
%matplotlib inline
font = FontProperties(fname = 'E:jupyternotebooksimhei.ttf') # 找系统里的一个汉字格式
# 修改背景为条纹
plt.style.use('ggplot')
classes = ['3班','4班','5班','6班']
classes_index = range(len(classes))
print(list(classes_index))
[0, 1, 2, 3]
student_amounts = [66,65,45,70]
# 画布设置
fig = plt.figure()
# 1,1,1 表示的是一张画布被切割成1行,1列共1张图的第一个;2,2,1表示一张画布被切割成2行2列4张图的第一个左上角
ax1 = fig.add_subplot(1,1,1)
ax1.bar(classes_index,student_amounts,align = 'center',color = 'darkblue')
ax1.xaxis.set_ticks_position('bottom')
ax1.yaxis.set_ticks_position('left')
plt.xticks(classes_index, classes,rotation = 0,
fontsize = 13,fontproperties = font)
plt.xlabel('班级', fontproperties=font, fontsize=15)
plt.ylabel('学生人数', fontproperties=font, fontsize=15)
plt.title('班级-学生人数', fontproperties=font, fontsize=20)
# 保存图片，bbox_inches='tight'去掉图形四周的空白
# plt.savefig('classes_students.png', dpi=400, bbox_inches='tight')
plt.show()
直方图
