Python Matplotl usage

[Ioncubekh]

I have upgraded my HP Prime firmware & got python. I tried running stuff & its works. But I cannot display plot. Steps while in Python Numeric View (Apps)

Code:

from math import *
from matplotl import *
uk_x= [0.1*i for i in range(-10,10)]
uk_x #displays correct list of values
uk_y= [cos(i) for i in uk_x]
uk_y #displays correct list of values
plot(uk_x,uk_y) # no error but nothing happens as well
plot.show() #nothing
show() #nothing

After reading this thread I realized how to transfer variables from python to ppl https://www.hpmuseum.org/forum/thread-18380.html

Now If i want to assign values (list) stored in uk_x & uk_y to native HP Prime list variables say L1 & L2 how should I proceed? These then can be used in Stats APP for plotting & further stuff
