gnuplot-py-users Mailing List for Gnuplot.py

Ok, but if you can do it in gnuplot, you can pass your own commands directly
via the pipe, see
http://gnuplot-py.sourceforge.net/doc/Gnuplot/__init__.html

So in gnuplot it works to do:

gnuplot>  plot x*x lc rgbcolor "blue"

Hence, in python we can do:

python
Python 2.5.2 (r252:60911, Jul 31 2008, 17:31:22)
[GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Gnuplot
>>> g1 = Gnuplot.Gnuplot()
>>> g1('plot x*x lc rgbcolor "blue"')
>>> g1('replot x lc rgbcolor "red"')
>>>

As you can make the above dynamic in your python script, you can do all.

As for index, I don't understand what you want to achieve, g1 above holds
the plot

Hope this helps

 I took a look at the test file and it had nothing about color is that I could
see.  Yes,  some of the method calls had color for an argument but it made no
sense.  Reading from the canoe plot manual, I tried to use the line style but,
that also failed.  I also couldn't see how to associate a particular index with
a plot.

Look in the gnuplot manual. You can do gnuplot commands with gnuplot-py.
Also have a look in the test file in subversion.

I'm trying to put before and after plots on the same image and I need each plot
to be in a different color.  How do I specify the color change in the plot method?

thanks

Hi,

Can anyone show me how to read data from a text file them plot it.

Thanks
Bryan Asis




      

Hi again,

By looking at the temporary files that Gnuplot.py generates, I finally
found out why I keep getting this warning. It is caused by the fact that
there is two newline characters at the end of these temporary files. I
removed one of the newlines and the warning was gone. To do this, simply
comment out the last line in the function write_array in utils.py:

-        f.write(nest_suffix)
+        #f.write(nest_suffix)

Hopefully, this will be fixed in the next release of Gnuploy.py.

Hi,

when I run the test.py script the following warning appears several times:

  Notice: Cannot contour non grid data. Please use "set dgrid3d".

Is there a way to get rid of this message? I am using the latest sources
from the SVN repository.

If anyone can help me out, or point me to where to look in the code, I
would be very happy.

Thanks,
Johannes
