Hi,
I've been having some problems trying some basic plotting commands with
gnuplot.py. My setup is the Python 2.3 Enthought edition and my script
looks as:
from scipy import *
from scipy import gplt
import scipy.io.array_ import
#import Gnuplot
filename = ('Default.PL1')
data = scipy.io.array_ import.read_arr ay(filename)
y = data[:,1]
x = data[:,0]
z = data[:,2]
gplt.plot(x,y,' with points')
gplt('set logscale x')
gplt('set logscale y')
With the following error message:
--->gplt('set logscale x')
TypeError: 'module' object is not callable
warning: Failure executing file: <data.py>
Any help would appreciated... 4 4551

Hi,
Try doing this:
import Gnuplot,Numeric
filename = ('Default.PL1')
data = scipy.io.array_ import.read_arr ay(filename)
y = data[:,1]
x = data[:,0]
z = data[:,2]
//I think u need to take the transpose of this column before
plotting..
x=Numeric.trans pose(x)
y=Numeric.trans pose(y)
g=Gnuplot.Gnupl ot()
d=Gnuplot.Data( x,y)
g('set logscale xy')
g.plot(d)
It should work...
Bye

Thanks for the response Varun,
I guess I still not sure the distingtion betweein gnuplot.py and its
implentation in scipy.
Still having some issues plotting:
In attempting as explained above:
import Gnuplot,Numeric
filename = ('Default.PL1')
data = scipy.io.array_ import.read_arr ay(filename)
y = data[:,1]
x = data[:,0]
z = data[:,2]
//I think u need to take the transpose of this column before
plotting..
x=Numeric.trans pose(x)
y=Numeric.trans pose(y)
g=Gnuplot.Gnupl ot(debug=1)
d=Gnuplot.Data( x,y)
g('set logscale xy')
g.plot(d)
The file executes without generating any plot being displayed however
the debug option generates this output:
gnuplot> set terminal windows
..
..
gnuplot> plot 'c:\documen~1\l eon\loca`l\temp \tmpuskt1' notitle
When I open this file in wordpad it contains the contents of the d
array.
Any ideas why gnuplot is not outputing to the screen??

The object "g" will be deleted when the scripts ends. When
that happens, the gnuplot process is killed. All this probably
happens before the plot window has been mapped to the display.
Add something like "sys.stdin.read line()" to the end of the
program so that it doesn't exit until you hit "Enter".

Hi,
I have a dictionairy containing DateTime objects as keys and integers as
values. What would be the easiest way to create a simple plot of these,
with a number axis versus a time axis? What library is the most
suitable for this? 'plot' on parnassus yields 18 hits, but since I have
zero experience, I don't know where to start. What makes it difficult
is that I have a time axis instead of a simple integer x-axis. Gnuplot

I am going to need to plot some data and formula results from Python. A
few years ago I used gnuplot (not from Python) and was wondering which
Python plotting module I should use (learn)?
I have seen DISLIN mentioned on "onlamp.com" and see that gnuplot has a
python module wrapper.
Any suggestions on Python plotting modules? (DISLIN or gnuplot.py or ????)
Thanks

I don't even know where to begin. This is just bizarre. I just picked
up the Gnuplot.py module (a light interface to gnuplot commands) and
was messing around with it today.
I've got a tiny script, but it only works from the command line about
half the time! In the python interpreter, 100%. Ipython, 100%. I'm
not kidding.

I´m using Gnuplot via gnuplot.py and I´m looking for a way to get the

Is there any method in gnuplot.py that does this for me?
If not, I tried something like:

Hi guys,
I have a quick question,
I have a program that generates numerical output (as most of the
programs), the program is written in C language, and currently I use
the "DOS interface to show the output when it is being generated.
is there a "short" and "non-complicated" code which plots the data
automatically instead of showing the numbers.

Hi there!
I need a C++ library that can organize and write scientific (and
numerical overall) data in tables. I have been fighting with
std::ofstream and plain ASCII files, but it is difficult to position
columns by an offset, impossible to draw table borders etc. I am
currently thinking of a class that is able to write to an html file,
e.g. As far as I know, html offers much better text (and table)
layout. And the format is portable!...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
