python中用ggplot绘制画图实例讲解

pip install pandas plotnine

ggplot(survs_df, aes(x='weight', y='hindfoot_length',
size = 'year')) + geom_point()

(ggplot(mtcars, aes(‘wt', ‘mpg', color='factor(cyl)'))
+ geom_point()
+ labs(title='Miles per gallon vs Weight', x='Weight', y='Miles per gallon')
+ guides(color=guide_legend(title='Number of Cylinders')) )

> import pandas as pd
> from ggplot import *
> df=pd.read_table('C:\Users\lenovo\Desktop\mtcars.txt')
> df
··name type number volume size other
0 td T 96 3 20 c
1 sf F 87 5 65 c
2 cc F 79 9 80 d

df.columns=['name','type','number','volume','size','other']
> p=ggplot(df, aes(x='number', y='volume', size='factor(size)', color='factor(other)'))+geom_point()
> print p
