python - tkinter and matplotlib: windows not showing until program closes under Linux -
i've written program plots different data upon pressing different buttons. program works intended under windows, when tried port linux (red hat v6) i'm getting strange issue: window want plot not appear until after close main program. happens regardless of figure (figure 1,2 etc.) i'm trying plot to, or if try type plt.show() etc.
the program i've written 1000 lines of code, created abbreviated program has same problem. works under windows, under linux have close root window matplotlib window appear.
working code:
import matplotlib.pyplot plt tkinter import * def click(): x=['0','1','2'] plt.plot(x,x) plotgui=tk() butt1=button(plotgui,text="test", command=click).grid() plotgui.mainloop()
if reduced code still not show tk-toplevel window, add line of:
plotgui.lift() # force wm raise tk() window plotgui.mainloop() if reduced code has problems matplotlib-wrapper, necessary more specific on wrapping method use matplitlib-output tkinter canvas et al.
if code attempts rely on default matplotlib tools alike plt.show() code suffer having 2 adjacent .mainloop()-s -- first tk()'s -- second 1 hidden in default matplotlib-s .show() -- , code become hardly controllable of 2 adjacent ui-s.
co-integrated ui
for having non-adjacent ui-controllers , more benefits of co-integrated ui, try re-use backends factories plot directly on tkinter.canvas , other plausible widgets of choice , control.
from matplotlib.backends.backend_tkagg import figurecanvastkagg and proceed integrated gui-mvc layers on both code & matplotlib model-state / inputs-controller / visual-output.
a bit of more code co-integrated ui sample:
