Thanks for the fast reply. I went a bit deeper into the code and i found where my problem was. The connect function comes from gobject, and the gobject.connect function accepts extra arguments that are passed to the connected function. So i can solve my problem by: <div>
<br></div><div>data.connect('new_data_point', analysis_client.update_plot, specific_arguments) </div><div><br></div><div>Bests,</div><div><br></div><div>Pierre<br><br><div class="gmail_quote">On Thu, Apr 12, 2012 at 9:21 AM, Peter Otten <span dir="ltr"><__<a href="mailto:peter__@web.de">peter__@web.de</a>></span> wrote:<br>

</div></div>Like Walter I have no idea what framework or library you are talking about.<br>
The generic answer is yes: Basically you have to make a new function that<br>
calls the method with a specifc plot instance.<br>
<br>
def update_specific_plot():<br>
analysis_client.update_plot(specific_plot_instance)<br>
data.connect("new_data_point", update_specific_plot)<br>
<br>
A more elegant and more general version of the above would create the helper<br>
function on the fly using functools.partial():<br>
<br>
from functools import partial<br>
<br>
data.connect("new_data_point",<br>
partial(analysis_client.update_plot, specific_plot_instance))<br>
<br>
