我怎么能在python中绘制字符串vs浮点数？

Question

如何使用pylab绘制string与float类型图？

x = ['PARIS','LONDON'] 

y = [2.39, 3.41] 

我怎么能绘制x与y？

Answer 1

非常感谢迈尔斯·贝克，这里是解决方案：

import pylab as pl 
x = [0,1] 
xTicks = ['LONDON','PARIS'] 
y = [2.39, 3.41] 
pl.xticks(x, xTicks) 
pl.xticks(range(2), xTicks, rotation=45) #writes strings with 45 degree angle 
pl.plot(x,y,'*') 
pl.show()
