python 2.7 - Raster plot not showing symbols using plt.scatter function -


i have raster plot, of 1 neuron, 10 trials of data , time 4500 ms. 

import numpy np import matplotlib.pyplot plt  #plotting 1 neuron 12 trials of info maatriks = [] in range(1,14):     if i<10:         string = 'c:\\users\\latel\\desktop\\kool\\neuro\\prax3\\data\\lgn\\plain\\neuron_01_stimulus_0'+str(i)+'.csv'     else:         string = 'c:\\users\\latel\\desktop\\kool\\neuro\\prax3\\data\\lgn\\plain\\neuron_01_stimulus_'+str(i)+'.csv' data_in = np.genfromtxt(string,dtype = 'int', delimiter = ',' or '\n') maatriks.append(data_in)  data = np.array(maatriks) print data.shape  spikes = np.array(data[8]) print spikes.shape  nonzeros = 0  i,item in enumerate(spikes):     nonzeros += np.count_nonzero(item)     plt.scatter(item, i*np.ones(item.shape), marker = '|') print nonzeros  plt.ylim(-1,len(spikes)) plt.xlim(0,len(spikes[0])) plt.xlabel("time seconds") plt.ylabel("trial number") plt.tight_layout() plt.show()

this outputs me(the prints) :

(13l, 10l, 4501l)

(10l, 4501l)

55

but plot empty , cannot understand why plot empty. there should 55 lines in opinion ...

edit: got working. added code.

for row in spikes:     in range(len(row)):         if (row[i] == 1):             row[i] =

because data 0 or 1.

anyone know how shorter ?
