Thread: [Matplotlib-users] plotfile: single column plot not working

I have a file with a single column of data like:

1
2
3
4

I would like to use the plotfile but it's returning the error:

File "/usr/lib/python2.5/site-packages/matplotlib/pyplot.py", line 1228, in
plotfile
  ax1 = fig.add_subplot(N,1,i)
UnboundLocalError: local variable 'N' referenced before assignment

Any help on making this work would be greatly appreciated.

Thanks for your help :)

It looks like you may have an old version of matplotlib, as this does
not appear to be a problem in recent versions:


In [3]: !cat test.dat
1
2
3
4

In [4]: plotfile('test.dat')


You may want to look into upgrading.
