python - Can a matplotlib figure object be pickled then retrieved? -

i trying pickle matplotlib figure object able regenerate graph x , y data , labels , title @ later time. possible?

when trying use open , dump pickle traceback:

#3rd party imports , built-in  import random import matplotlib.pyplot plt  import pickle pk  #initializing lists x , y values. voltage trim , current measure our x , y in case.  voltage_trim = range(100, 150) current_meas = []  # change of parameters modelled multiplier in case multiplier = range(1,4)  # initializing lists store output current if wanted      current_storage = []   # required matplotlib plt.close() plt.ion() #required method call in order interactive plotting work   # specify graph fig1 = plt.figure() ax = fig1.add_subplot(1,1,1) # creates axis in order have multiple lines  plt.title('voltage trim vs current \nsome fancy sub-title here') plt.xlabel('voltage trim / v')       plt.ylabel('current measured/ a') plt.grid(true)    color_choices = ['k', 'g','r','b','k','c', 'm', 'y']  # add more according number of graphs    # main test loops   this_mult in multiplier:          current_meas = [] # clears output list graph different multipier       #enumerates input in order manipulate below           index, value in enumerate(voltage_trim):            #generating random current values in case          current_meas.append(random.randint(0,10)*this_mult)          print index ,'generating results...'         print index, value          # increments index lists match dimensiosn , graphing possible                  index += 1          # optional real time plotting function, comment out if not wanted          live_plotting = ax.plot(voltage_trim[:index], current_meas, color = color_choices[this_mult])#,label = 'line'+str(this_mult)          # pyplot method pauses loop, updates graph , continues enable real time graphing, set small number considered insignificant          plt.pause(1e-124)           # deletes real time line save memory in loop                  live_plotting[0].remove()      # actual storage of plot objects, specify legend label here, , other arguments same         ax.plot(voltage_trim, current_meas,color = color_choices[this_mult],marker = 'o', label = 'line'+str(this_mult))            #stores measured current (a)         current_storage.append(current_meas)      #calls legend - must in outer loop          plt.legend()  f = open('testt','wb') pk.dump(fig1, f) f.close()  

yes. try

import pickle import matplotlib.pyplot plt  file = open('myfile', 'wb') fig = plt.gcf() pickle.dump(fig, file) file.close() 

then read

file = open('myfile', 'rb') pickle.load(file) plt.show() file.close()
