Hi Wal?ria,
We can't easily fix your problem without knowing what data f and
Sserie contain. It would help us to help you if you could post a
standalone example that shows your problem without relying on external
data.

Angus is correct that providing a stand-alone version of the script that
replicates your problem would be most useful. I would like to mention a
couple of possible improvements to your code. These improvements may or
may
not fix your issue, but they will improve your current code.
1) Use list comprehensions
Change
y=[]
for n in f:
y.append(n/Decimal(1000))
y = numpy.array(y)
into:
y = numpy.array(f) / 1000.0
Also,
ax.grid('TRUE')
should be:
ax.grid(True)
I hope this helps. If not, then please send a stand-alone example that
duplicates the problem you are having.
Ben Root

Hi,
How does one plot an arrow in a log log plot? In the following example, I
can't get the arrow head, regardless of what value I use for the head width:
import matplotlib as mpl
mpl.use('Agg')
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(1,1,1)
ax.arrow(0.2,0.2,0.5,0.5,head_width=1.)
ax.set_xscale('log')
ax.set_yscale('log')
ax.set_xlim(0.1,1.)
ax.set_ylim(0.1,1.)
fig.savefig('test.png')
In addition, the documentation for arrow does not even mention any arrow
specific options such as the head width/length, and the example plot is
