[Gnuplot-info] Do a Gnuplot of a file in python

[Santix <san...@gm...>]

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:

g.load(power.p)

but it gives me this error:

Traceback (most recent call last):
  File "./spectrum_output.py", line 310, in <module>
    main_loop(tb)
  File "./spectrum_output.py", line 289, in main_loop
    g.load(power.p)		
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 'm.data[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!

Regards,

Santiago Ortega.

I'm reasonably sure that this has absolutely nothing to do with gnuplot. 
  It may have something to do with gnuplot.py --- but that's not 
produced by us.  Or it may be a plain an simple mistake in how you used 
Python.

So I can only offer a wild guess: try putting "" around the filename, i.e.:

	g.load("power.p")
