I have simple python code to read data file and plot graph. It works well in previous system. My system was crashed, I setting another system with higher ubuntu version. When I run script, I faced error which is not exist in previous system. Previous system was broken, I cannot compare in detail.
Code
import matplotlib.pyplot as plt
import csv
import sys
def analyze():
datafile = sys.argv[1]
pieces = []
with open(datafile, 'rt') as f:
data = csv.reader(f,delimiter = '\t')
for d in data:
pieces.append(d)
x = [op for op, response, interval in pieces]
#y1 = [response for op, response, interval in pieces]
y1 = [interval for op, response, interval in pieces]
p1 = plt.plot (x, y1, label='test')
plt.legend()
plt.title ('AAAAA test')
plt.xlabel('# of Operation'), plt.ylabel('Response time')
#plt.hist(y1, 100)
plt.show()
if __name__ == '__main__':
analyze()
