[Gnuplot-py-users] how to put a gnuplot graph in a canvas

[Launay Pierre-A. <Pie...@ac...>]

On mandrake 8.2 I can't work on gnuplot graph , I can put a canvas and 
use it to redraw a gnuplot graph but I can't use the mouse and work 
with it in python in the gnuplot graph.
Excuse me for my english 
Thanks

I think you are just missing g("set hidden").  The following plots a 
sphere for me with hidden-line removal:

import math
import Gnuplot, Numeric, raster
from Numeric import NewAxis

theta = raster.raster(0, math.pi, 18, 0, 19)
phi = raster.raster(0, 2.0 * math.pi, 36, 0, 37)

xyz = Numeric.zeros((len(theta), len(phi), 3,), Numeric.Float64)
xyz[:,:,0] = Numeric.sin(theta[:, NewAxis]) * Numeric.cos(phi[NewAxis, :])
xyz[:,:,1] = Numeric.sin(theta[:, NewAxis]) * Numeric.sin(phi[NewAxis, :])
xyz[:,:,2] = Numeric.cos(theta[:, NewAxis]) + (phi[NewAxis, :] * 0)

g = Gnuplot.Gnuplot()
g('set parametric')
g('set hidden')
g('set data style lines')

g.splot(xyz)

raw_input("Press return to continue")

Hope this helps,
Michael

[Gnuplot-py-users] parametric surface plots...

[Andy S. <an...@a2...>]

Hi all.

I want to make parametric surface plots, but I can't figure out how to do
it with Gnuplot.py.  I've seen plenty of examples done with gnuplot
functions, but... how to provide my own data?

I can do something like this: (pseudocode)

u = aspan(-0.5*Pi, 0.5*Pi, 100)
v = aspan(0, 2.0*Pi, 100)
uv = cartesian_product(u, v)
g('set parametric')
g.splot(GridData(cos(uv[0])*cos(uv[1]), cos(uv[0])*sin(uv[1]), sin(uv[0]),
type='lines'))

Sure enough, it plots a sphere as expected, but its a line trace not a
true surface, e.g. it can't hide backfaces...

I've seen plenty of examples online using gnuplot's internal functions,
but I've got no idea how to do a parametric surface from input data...  
is this possible?

Thanks,
Andy.

Hi, all I had to do was edit line 38 of "gp_win32.py" in the directory
where you installed Gnuplot.py, and set the correct gnuplot_command
variable.  In order to have it work with spaces in the path, you have to
do it like the example and enclose quotes in the quotes.  I am using
winXP and Gnuplot 1.7 as well

Re: [Gnuplot-py-users] labeling question

[<kai...@t-...>]

Hello,

There is no explicit support for the "set label" command in Gnuplot.py, 
but you can easily do this using the ability to pass arbitrary commands 
to gnuplot:

    for (x,y,code) in data:
        g('set label "%s" at %g,%g' % (code, x+xoffset, y+yoffset))

where xoffset and yoffset are chosen so that the label does not 
overwrite the point itself.

Hope this helps,
Michael

Re: [Gnuplot-py-users] Gnuplot.py, Numeric, and numarray

Yes, and moreover, there is a list of differences between the two here:
http://www.stsci.edu/resources/software_hardware/numarray/userguide

It seems like the differences should not affect Gnuplot.py,
but this is a question for Michael perhaps.

Howabout a condicional import in the relevant modules? (funcutils, etc)
Something like:

####
try:
    import Numarray as numeric_lib
except:
    import Numeric as numeric_lib
####

And then all internal references are made to "numeric_lib",
for instance 

return numeric_lib.asarray(m, Numeric.Float32)

I think it is fare to assume that the user will prefer Numarray
if installed, and I also think that Numeric will be around
for a loooong time. Sounds reasonable ?

pyfits and PyRAF use numarray instead of Numeric, so I have used

Everything seems to work fine. I think numarray tries to be

I haven't actively been following the development of numarray, but I 
understand that it is almost identical to Numeric.  Does anybody know of 
any differences that would be relevant to Gnuplot.py?  Is it imported 
under a different name, or does one still "import Numeric"?

If Gnuplot.py would require changes to use numarray, then the most 
important question is when to make the transition.  It's unlikely that 
the whole Python community will switch from one library to the other on 
the same day!

Ideally, there would be a way to use Numeric and/or numarray and/or 
JNumeric or none of the above (native Python sequences).  There would 
need to be a way to decide which to use at the time that Gnuplot.py is 
imported.

Anybody have any thoughts on this issue?

Michael

Re: [Gnuplot-py-users] 1.7 problem

Hello,

I guess nobody has responded to this email?

I don't use windows, but I believe that this problem usually indicates 
that gnuplot (i.e., the program, not the Python interface) didn't start 
up correctly.  It could be a PATH problem, for example.  If you search 
the mailing list archives you will see several similar questions and 
responses.

Hi Tom

You need to install the numeric extension to python.
http://www.pfdubois.com/numpy/

You can install from source, but also
some linux distributions include it.
For instance, in my Mandrake 9.2 the package is 
python-numeric-22.0-4mdk

Hello,


I've got a problem with the installation of gnuplot-py. I tried to
install gnuplot-py like in the README file or on the webpage:

1. Download gnuplot-py-1.7.tar.gz
                                                                       
                                                 
2. Extract the archive to a temporary directory. I used tar -xvf
gnuplot-py-1.7.tar.gz
                                                                       
                                                     
3. Install by changing to the directory and typing "python setup.py
   install".

When I gave the command python setup.py install , the computer gave this
output :
Traceback (most recent call last):
  File "setup.py", line 17, in ?
    from __init__ import __version__
  File "__init__.py", line 167, in ?
    from PlotItems import PlotItem, Func, File, Data, GridData
  File "PlotItems.py", line 26, in ?
    import Numeric

I don't know what the problem is. Has somebody been having the same
problem ?

The styles of plotting are documented within gnuplot under the help 
system; type "help plot with" and "help set style" to get info.  To plot 
with errorbars under Gnuplot.py, you need either 3 (x,y,delta) or 4 
(x,y,ylow,ymax) columns of data and then specify the "with='errorbars'" 
option:

 >>> import Gnuplot
 >>> g = Gnuplot.Gnuplot()
 >>> g('set xrange [0:5]')
 >>> g.plot(Gnuplot.Data([[1,2,0.1],[2,3,0.2], [3,4,0.3]], 
with='errorbars'))
 >>> g.plot(Gnuplot.Data([[1,2,1.5,2.2],[2,3,2.8,3.3], [3,4,3.2,4.7]], 
with='errorbars'))

Hope that helps.

Re: [Gnuplot-py-users] gnuplot-py 1.7 and gnuplot 3.8 mouse-interaction conflict

[<kai...@t-...>]

Nadav,

The dependence on the version of Gnuplot.py is strange.  Aside from the 
difference between FIFOs and temporary files, which the option change 
reverses, I don't understand why they behave differently.  Do you need 
to use a different gnuplot terminal type to get the mouse features?  If 
so, there is an option "default_term" in gp_*.py that you might try 
playing with.

I suggest that you create the Gnuplot object with the option 
Gnuplot(debug=1).  This will display each of the commands being sent by 
Gnuplot.py to gnuplot.  If you compare the commands sent by 1.6 and 1.7 
the difference might lead you to an explanation.

I currently don't have gnuplot 3.8 installed on my computers so I can't 
test things myself.  I'll try it out when I get a chance (which might 
not be very soon).

RE: [Gnuplot-py-users] gnuplot-py 1.7 and gnuplot 3.8 mouse-interaction conflict

[Nadav H. <na...@vi...>]

Thank you for your replay, I'll try to make the patch and test it again.
The option to mouse-interact with gnuplot's graphics window  was =
introduced in gnuplot 3.8. It works under X11, and win32 and probably =
under some other OS's.
I have tested gnuplot-py 1.7 + gnuplot 3.8 combination only under =
gnu/linux. I had no problems with gnuplot-py 1.6 + gnuplot 3.8 under =
win32.

Sorry I didn't respond earlier.  I was on vacation.

I am not familiar with the commands that you mentioned.  On what gnuplot =

terminal type?

If this feature causes gnuplot.py to read the input file twice, that=20
would indeed be a problem when working with FIFOs.  Normally, as soon as =

the FIFO has been read once by gnuplot, it is deleted.  It would be=20
possible to keep the FIFO around for possible repeated reads, but this=20
would defeat the purpose of the FIFO (which was to enable Gnuplot.py to=20
know when it is safe to discard old data).

As for a workaround, you can go back to using temporary files as a=20
default by going to the gp_*.py file specific to your platform (e.g.,=20
gp_unix.py or gp_macosx.py) and changing the option "prefer_fifo_data" =
to 0.

Sorry I didn't respond earlier.  I was on vacation.

I am not familiar with the commands that you mentioned.  On what gnuplot 
version and platform are they?  Are they specific to a particular 
terminal type?

If this feature causes gnuplot.py to read the input file twice, that 
would indeed be a problem when working with FIFOs.  Normally, as soon as 
the FIFO has been read once by gnuplot, it is deleted.  It would be 
possible to keep the FIFO around for possible repeated reads, but this 
would defeat the purpose of the FIFO (which was to enable Gnuplot.py to 
know when it is safe to discard old data).

As for a workaround, you can go back to using temporary files as a 
default by going to the gp_*.py file specific to your platform (e.g., 
gp_unix.py or gp_macosx.py) and changing the option "prefer_fifo_data" to 0.
