I am doing a python program that save the data in a text file in columns and
I want to do a gnuplot to plot the results.
But I want the program in python to show the result with gnuplot.
I have tried this:


but it gives me this error:

Traceback (most recent call last):
  File "./", line 310, in <module>
  File "./", line 289, in main_loop
AttributeError: 'file' object has no attribute 'p'

On power.p I have this:

set autoscale
unset logscale
unset label
set xtic auto
set ytic auto
set title "Spectrum Analyzer"
set xlabel "Frecuency"
set ylabel "Power (dB)"
plot "power.dat" using 1:2 title '[0]' with linespoints

And in power.dat:
2231500000.0    18.2582263947
2234500000.0    17.0396003723
        ...                      ...
with more data

It goes ok when I load it in gnuplot, but not when I execute the python
program in the Terminal.

Thanks in advance!
