感谢您花时间阅读它,也许这是一个简单的问题 . 我有这样的文件(它们就像200个文件):

Output of SMC2FS2: FAS for file 20123427.CB2A.BHE.sac.smc
 Nfreq_out = 
   8192
           freq            fas

要阅读它们,要跳过 Headers 并开始处理:

#define the path where I have the 200 files
pato='D:\\Seismic_Inves\\flc_grant\\120427\\smc2fs\\smooth'
os.chdir(pato)
lista=[]
#list all files with "kono_" 
for a in glob.glob('*kono_*'):
    lista.append(a)
#read and skip the header for all files
for archis in lista:
    with open(archis,'r') as leo:
       for _ in range(4):
            next(leo)
#start the proccesing
       for line in leo:
           leo=[x.strip() for x in leo if x.strip()]
           leos=[tuple(map(float,x.split())) for x in leo[1:]]
           f=[x[0] for x in leos]
           fas=[x[1] for x in leos]
           plt.figure(1)
           plt.plot(f,fas,'r')
           plt.yscale('log')
           plt.xscale('log')
           plt.show()

你可以想象这是一个频率与幅度(FAS图)的图 . 代码运行良好,但打开一个图并只绘制一个文件,然后我需要关闭图,它将绘制第二个文件,依此类推 .

问题是:

如何在一个图中绘制所有数据(200 fcsv iles) . 到@GlobalTraveler,这是使用你的建议的结果:

    将块参数添加到show - > plt.show(block = False)或在for循环外移动show

    然而,在grandscheme的东西,我建议将代码移动到更多面向对象的方法 . 例如:

    #define the path where I have the 200 files
    from matplotlib.pyplot import subplots, show
    pato='D:\\Seismic_Inves\\flc_grant\\120427\\smc2fs\\smooth'
    os.chdir(pato)
    lista=[]
    #list all files with "kono_" 
    for a in glob.glob('*kono_*'):
        lista.append(a)
    #read and skip the header for all files
    
    fig, ax  = subplots() # open figure and create axis
    for archis in lista:
        with open(archis,'r') as leo:
           for _ in range(4):
                next(leo)
    #start the proccesing
           for line in leo:
               leo=[x.strip() for x in leo if x.strip()]
               leos=[tuple(map(float,x.split())) for x in leo[1:]]
               f=[x[0] for x in leos]
               fas=[x[1] for x in leos]
               ax.plot(f,fas,'r') # plot on this axis
    ax.set(**dict(xscale = 'log', yscale = 'log')) # format the axis
    show() # show
    

    这是你的建议的结果FAS_konoomachi_smooth
