When I try to make a legend after using the vlines command, I get a
_legmarker error.
my code:
···
plot(two_theta,y_value_list_1)
vlines(two_theta,[0],y_value_list_2,linewidth = 2)
legend([‘1’,‘2’])*
the error:
_Exception in Tkinter callback

I guess this is a known bug and already fixed. Maybe ubuntu 9.4 sheeps
with the older version though (the bug was fixed in this January, so,
I'm not sure).

You may try to install the latest version. Or you may use the option 4
as a work around.
