It is already possible to use

    g.hardcopy(filename='myfile.png', terminal='png')

with some other option possibilities (fontsize, monochrome, etc) defined
in termdefs.py within terminal_opts['png'].

Is this what you need?

Re: [Gnuplot-py-users] Mouse Zoom

[Nadav H. <Na...@Vi...>]

Either go back to version 1.6 of browse in this mailing list, there is a
line that you can change in the configuration that solve this issue on
some occasions. The problem of mouse interactions of gnuplot4 through
gnuplot-py raised more then once.

[Gnuplot-py-users] png support

[Noel O'B. <no...@ca...>]

It seems that at the moment, it is only possible to save images as .ps.
This is a problem for any Python programs that want to display the image
(e.g. using Tkinter).

Would it be difficult to add .png support?

Noel.

[Gnuplot-py-users] Patch for mishandled filenames

[Noel O'B. <no...@ca...>]

Dear all,

Please find attached a patch for the following problem:

Problem:

On Windows, if your user name contains an apostrophe, the use of
temporary files causes an error, as gnuplot uses apropostrophes (i.e.
single quotes) to delimit the filename.

gnuplot> plot 'c:\docume~1\noelo'~1\locals~1\temp\tmpcxnwsm' notitle
                                   ^
         invalid character


Solution:

If you replace the single quotes with double quotes, gnuplot is happy
with the apostrophe but misinterprets the backslashes as escape
character sequences.

gnuplot> plot "c:\docume~1\noelo'~1\locals~1\temp\tmpcxnwsm" notitle
              ^
         can't read data file "c:docume~1
oelo'~1locals~1 emp     mpcxnwsm"

....so you need to also replace all of the backslashes with forward
slashes.

gnuplot> plot "c:/docume~1/noelo'~1/locals~1/temp/tmpcxnwsm"
notitle            

**Success!!**

You may not want to rely on scipy.gplt.  It is deprecated and has been removed

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.

[Including the above paragraph :-) ]

I just added this question to the FAQ.

Windows users are encouraged to submit a patch to produce a better error
message for this situation.  It would help new users a lot.  (Just
remember that it has to work for all windows versions.)

g.plot(results)

I think something like 

Gnuplot.GnuplotOpts.default_term = "newDefaultTerminal"
g = Gnuplot.Gnuplot()

can be used.

[Gnuplot-py-users] Setting default terminal type

[Arne M. <mej...@cs...>]

Hi,

I'm curious as to whether there is an easier way of changning the
default terminal type, than to edit default_term in the gp_unix.py
file. 

My setup is such that I use Gnuplot-py to generate plots on the fly on
my webserver, which does not have x11 installed. 

As far as I can tell, there is no way of setting the terminal before
creating a Gnuplot instance, other than editing the source file. Am I
wrong?

I would consider it a nicer solution if you could specify this by
something like:

g = Gnuplot.Gnuplot(term="png", debug=1)

This way I will not have to edit the gp_unix.py when
upgrading/reinstalling Gnuplot-py.

Best Regards,
Arne Mejlholm

    g.plot(Gnuplot.File('temp/spectra'+str(i)+'.dat', using=1:2))

I recommend looking in demo.py for lots of examples like this.

Re: [Gnuplot-py-users] plotting

Dear Michael,

Thank you for the answer. Indeed it works like this now.
The structure of the files however, require that the command in gnuplot is:

plot 'temp/spectra9.dat' u 1:2

otherwise the file cannot be plotted (bad data in line 0)
so is there a way to incorporate the 'u 1:2' command in the g.plot 
command that you siggest?

g.plot(Gnuplot.File('temp/spectra'+str(i)+'.dat'))

thank you
Zoe

To plot a file, you don't open the file using Python but rather pass the
plot method a Gnuplot.File object, like

    g.plot(Gnuplot.File('temp/spectra'+str(i)+'.dat'))

With that change, I think it should work.

(Of course, you could alternatively open the file using python, read the
data into a python array, then plot the array, but that approach doesn't
have any advantages unless you want to process the data before plotting it.)

[Michael H. <mh...@al...>]

Hello,

There is no provision in Gnuplot.py for this.

Regarding your attempt, I'm pretty sure that setting sys.stdout doesn't
have any effect on spawned programs.  And certainly not after the
program is already running.

Why don't you write the PNG to a temporary file then read that?

[Gnuplot-py-users] get png output as string

[Nicola K. <Nic...@ur...>]

Hi,

is there any method which I haven=B4t found yet in gnuplot.py to get =
what=20
would otherwise be printed on stdout?

What I actually want to do is to set my terminal to png and have the=20
binary-png-code stored in a string instead of a file or piped to=20
stdout.

I treid something like:

p=3DGnuplot.Gnuplot(debug=3D1)
p('set terminal png')
oldstdout=3Dsys.stdout
output=3DcStringIO.StringIO() # IO-String instanzieren
sys.stdout=3Doutput # stdout nach output umleiten
p.plot([[1,0],[2,50],[3,0],[4,20],[5,0],[6,30],[7,70], [8,70], [9, 75],=20=

[10, 50], [11, 30], [12, 50]])


sys.stdout=3Doldstdout
print output.getvalue()

But unfortunatelly I also get other stuff like
"gnuplot: unable to open display ''
"gnuplot: X11 aborted"

Can anyone help me on that?

Thanks,
Nicola

What you want is

    g.plot(*mags)

or, if you are using an older version of Python,

    apply(g.plot, tuple(mags))

Hi,

I think g.plot() eats Gnuplot.Data objects, not lists. 

So you can have g.plot(data1, data2, ... dataN)
but not g.plot([data1, data2, ... dataN])

Copies of all input to g.plot is added to g.itemlist... after the command 
above you have g.itemlist as [data1, data2, ..., dataN].

To add a line to the plot after g.plot(data) you could use 

newdata = Gnuplot.Data(whateveryouhave)
g.replot(newdata)

Now the itemlist would be [data1, data2, ..., dataN, newdata].

The way I remove stuff from the itemlist is a bit ugly.

If you know the position of the unwanted item in the datalist (here 
assumed 1), you can do

del g.itemlist[1]

This does not delete you data, only the copy stored in the itemlist.
After del, the itemlist would be [data1, data3, ..., dataN, newdata] 
Then use

g.refresh() 

to update the plot and data2 is no longer visible. For this you need your 
own bookkeeping on the data in itemlist, to know the indices. If the 
itemlist goes empty you might get trouble.
