However, due to the huge data(a list containing about 100,000 numbers) I sent to the hist() function, error will arise when draw two figures. But it goes smoothly while only drawing either of the two plots. Could anyone help me to deal with this? Thanks in advance. Here is the simplified code to show the error: f_120 = pip install matplotlib plt.figure(1) plt.hist(taccept_list, bins=6000000, normed = True, histtype ="step", cumulative = True, color = 'b', label = 'accepted answer') plt.hist(tfirst_list, bins=6000000, normed = True, histtype ="step", cumulative = True, color = 'g',label = 'first answer') plt.axvline(x = 30, ymin = 0, ymax = 1, color = 'r', linestyle = '--', label = '30 min') plt.axvline(x = 60, ymin = 0, ymax = 1, color = 'c', linestyle = '--', label = '1 hour') plt.legend() plt.ylabel('Percentage of answered questions') plt.xlabel('Minutes elapsed after questions are posted') plt.title('Cumulative histogram: time elapsed \n before questions receive answer (first 2 hrs)') plt.ylim(0,1) plt.xlim(0,120) f_120.show() f_120.savefig('7month_0_120.png', format = 'png' ) plt.close() f_2640 = plt.figure(2) plt.hist(taccept_list, bins=6000000, normed = True, histtype ="step", cumulative = True, color = 'b', label = 'accepted answer') plt.hist(tfirst_list, bins=6000000, normed = True, histtype ="step", cumulative = True, color = 'g',label = 'first answer') plt.axvline(x = 240, ymin = 0, ymax = 1, color = 'r', linestyle = '--', label = '4 hours') plt.axvline(x = 1440, ymin = 0, ymax = 1, color = 'c', linestyle = '--', label = '1 day') plt.legend(loc= 4) plt.ylabel('Percentage of answered questions') plt.xlabel('Minutes elapsed after questions are posted') plt.title('Cumulative histogram: time elapsed \n before questions receive answer (first 48)') plt.ylim(0,1) p
