Hi,

I tried to plot a graph but when I run my script, I received the following 
error:


ozge@ozge-Inspiron-15-7000-Gaming:~/workspace$ python plottt.py
Traceback (most recent call last):
  File "plottt.py", line 55, in <module>
    store(a1,dataFile1)
  File "plottt.py", line 7, in store
    data=loadtxt(textFile,skiprows=1)
  File "/usr/lib/python2.7/dist-packages/numpy/lib/npyio.py", line 927, in 
loadtxt
    % line_num)
ValueError: Wrong number of columns at line 87


There isn't any problem about column numbers. It is probably about the format 
of the data. However, I do not know hot to fix it.

If anyone helps me about this issue, I'll be appreciated.

thanks,

ozge


here is my script:

def store(var,textFile):
    data=loadtxt(textFile,skiprows=1)
    it=[]
    t=[]
    e1=[]
    e2=[]
    e3=[]
    ev=[]
    s1=[]
    s2=[]
    s3=[]
    q=[]
    tc=[]
    sc=[]
    c=[]
    uf=[]
    for i in range(0,len(data)):
      it.append(float(data[i,3]))
      t.append(float(data[i,8]))
      e1.append(-float(data[i,0]))
      e2.append(-float(data[i,1]))
      e3.append(-float(data[i,2]))
      ev.append(float(data[i,0]) + float(data[i,1]) + float(data[i,2]))
      s1.append(-float(data[i,4]))
      s2.append(-float(data[i,5]))
      s3.append(-float(data[i,6]))
      q.append(-float(data[i,5])+float(data[i,4]))
      tc.append(float(data[i,9]))
      sc.append(float(data[i,7]))
      c.append(float(data[i,9]) + float(data[i,7]))
      uf.append(float(data[i,10]))
    var.append(it)
    var.append(t)
    var.append(e1)
    var.append(e2)
    var.append(e3)
    var.append(ev)
    var.append(s1)
    var.append(s2)
    var.append(s3)
    var.append(q)
    var.append(tc)
    var.append(sc)
    var.append(c)
    var.append(uf)
   
## data input

ylabel('microcracks [-]')
