控制顏色順序，並在y = 0處畫一條線

Question

我想從這兩組數據中作圖。這是工作，除了顏色。我試圖匹配ufiles和dfiles的顏色，以使ufile [1]和dfiles [1]中的行具有相同的顏色。

我怎麼能得到它？通過colors

#!/usr/bin/env python3 
# import np 
import pylab 

ufiles = ["dos_u_Co.dat", "dos_u_Fe.dat", "dos_u_Re.dat", "dos_u_tot.dat"] 
dfiles = ["dos_d_Co.dat", "dos_d_Fe.dat", "dos_d_Re.dat", "dos_d_tot.dat"] 
colors = ('b', 'g', 'r','c') 


datalist = [ (pylab.loadtxt(filename)) for filename in ufiles ] 
for data in datalist: 
    pylab.plot(data[:,0], data[:,1], label=datalist) 

datalist = [ (pylab.loadtxt(filename)) for filename in dfiles ] 
for data in datalist: 
    pylab.plot(data[:,0], -1*data[:,1], label=datalist) 

pylab.show() 

Answer 1

只是週期你循環使用，雖然zip，然後使用color kwarg集劇情顏色datalist：

import pylab 

ufiles = ["dos_u_Co.dat", "dos_u_Fe.dat", "dos_u_Re.dat", "dos_u_tot.dat"] 
dfiles = ["dos_d_Co.dat", "dos_d_Fe.dat", "dos_d_Re.dat", "dos_d_tot.dat"] 
colors = ('b', 'g', 'r','c') 


datalist = [ (pylab.loadtxt(filename)) for filename in ufiles ] 
for data, color in zip(datalist, colors): 
    pylab.plot(data[:,0], data[:,1], color=color, label=datalist) 

datalist = [ (pylab.loadtxt(filename)) for filename in dfiles ] 
for data, color in zip(datalist, colors): 
    pylab.plot(data[:,0], -1*data[:,1], color=color, label=datalist) 

pylab.show()
