Hi there,
I have a question regarding plotting with Python.
I have the following python script:
# coding: utf-8
from pylab import *
import numpy
filename='ourtest_out.list'
fh=open(filename)
line=fh.readline()
fh.close
z=array([ float(val) for val in line.split()[1:] ])
a = numpy.loadtxt(filename,skiprows=3)
N=100
t = a[:,0]
nu = a[0:,1:N+1]
#Conc = a[1:,N+1:]
Conc = a[1:,N+1:]
levels=arange(-10,1)
levels=levels[-3]-levels
t=t/360.
figure()
plot(Conc[0],z)
xlabel('C')
ylabel('z')
#show()
savefig('Conc.png')
close()
#########nu
figure()
lw = 2.0 #linewidth
dpi = 96
levels=arange(-10,1)
levels=levels[-3]-levels
plot(nu[0],z)
xlabel('nu')
ylabel('z')
savefig('nu.png')
close()
--------However, once I run the program (run.py)
I have error like this:
---------------------------------------------------------------------------
ValueError Traceback (most recent call last)
/Users/…./run.py in <module>()
24
25 figure()
---> 26 plot(Conc[0],z)
27
28 xlabel('C')

293

296 if self.command == 'plot':

232 y = np.atleast_1d(y)
233 if x.shape[0] != y.shape[0]:
--> 234 raise ValueError("x and y must have same first dimension")
235 if x.ndim > 2 or y.ndim > 2:
236 raise ValueError("x and y can be no greater than 2-D")
ValueError: x and y must have same first dimension
-------So, What would you suggest?
Thanks in advance,
Sue
