wanted to use in parallel the timer to "refresh" the graph and a while
loop to "extract" the datas.
If I use startTimer(0) it works but the GUI is almost unresponsive.

see the window appears...

anything...

Hello everyone,
I try to plot the digamma function of (1/2 + 1/x) but I'm not sure that I'm
plotting the good one.
I've tried:
special.polygamma(0, (1/2 + 1/x))
and
special.polygamma(1, (1/2 + 1/x))
but I don't have the same result as with mathcad.
I've tried to code it like that:
def F(x):
Thanks! The problem came from the 1/2 ! For convenience I've found the
function digamma on numpy
*http://docs.scipy.org/doc/scipy/reference/generated/scipy.special.psi.html
But it's quite hard to find it! Maybe we can ask to add digamma in the
title between parenthesis?
