Waveform is attached. All waves are starting at 0. Each wave form should be shifted from zero. So that i can visualize each wave form. Pl. help me. Thanks. Mohamed ali Code : import obspy from obspy.io.segy.core import _read_segy import pandas as pt import numpy as np import matplotlib.pyplot as plt st = obspy.read("Filename.segy") # this file is having # 10 traces(waveform) length=len(st) for i in range(0,length): x= st[i].data y=st[i].times() fig =plt.plot(x,y) plt.suptitle('vsp wave form', fontsize=14, fontweight='bold') plt.xlabel("time in seconds") plt.ylabel("amplitude") plt.show() -------------- next part -------------- An HTML attachment was scrubbed...

By using the code , individually i can display. But i wanted to display all wave forms together, so that quality control may be carried out.

Message-ID: Hello all, I have few programs that fail due to string concating error. result = variableA + variableB When variableB is int, it gives type error. Usually I forget to add type casting for the variables. Why to avoid this frequent error? I use emacs editor in Ubuntu Linux. Adding typecast is the only way to avoid this. But how do you all remember this? Is there any easy reminder or error pointer in any other IDE or Tools? Thanks. -------------- next part -------------- An HTML attachment was scrubbed...
