matplotlib简单的使用(二)

1、折线图

import matplotlib as mlb
from matplotlib import pylab as pl


# 折线图
# 分别创建x,y坐标
x = [1,3,5,7,6,9,10,13,16]
y = [3,4,5,7,9,0,1,2,3]
# 设置标题
pl.title("plot of x ")
# 将坐标内容增加进表格
# 第三个参数是展示的颜色
pl.plot(x,y,'r')
# 将图表展示
pl.show()

颜色参数与对应的颜色:

b:blue   g:green  r:red  y:yellow  k:black  w:white

结果:

2、散点图

散点图的写法和折线图一致,只需要在颜色参数中增加o即可,eg:pl.plot(x, y)改成pl.plot(x, y, 'or')

3、柱状体的生成,用的是bar

 1 from matplotlib import pylab as pl
 2 
 3 
 4 x = [1,3,5,7,6,9,10,13,16]
 5 y = [3,4,5,7,9,2,1,2,3]
 6 
 7 pl.title("bar of x ")
 8 pl.bar(x,y)
 9 
10 pl.show()

结果:

4、饼状图,pie

1 from matplotlib import pylab as pl
2 
3 
4 x = [7,6,9,10,13,16]
5 
6 pl.title("pie of x ")
7 pl.pie(x)
8 
9 pl.show()

结果:
