Removing matplotlib plot figure from tkinter - matplotlib

Question

I am building a control app, and i use a matplotlib.figure graph to represent some data. I made a function that will do the plotting, but the problem is removing the plot. I can't remove the plot from the window, as it just stays there no matter what. I've tried using tk_widget.place_forget(), tk_widget.destroy(), and figure_subplot.remove(), but the window stays there.
def plot_box_1(sx, sy, px, py):
fig = Figure(figsize=(sx/100, sy/100), dpi=100)
pl1 = fig.add_subplot(111)
pl1.plot(y)
pltwidget = FigureCanvasTkAgg(fig, master=window)
pltwidget.draw()
tkplt = pltwidget.get_tk_widget()
tkplt.place(x=px, y=py)
return tkplt, pl1
def b5_updater():
global tab, asdf, current_after
p1 = page[5]["p1"]
p2 = page[5]["p2"]
box_pos = page[5]["box_pos"]
if tab == 5:
if asdf == 100:
asdf = 0
p1['value'] = asdf
p2['value'] = 100 - asdf
y.append(asdf)
if len(y) >= plot_lim:
y.pop(0)
asdf += 1
page[5]["plt_wid"], page[5]["pl1"] = plot_box_1(250, 180, box_pos[2][0] + 25, box_pos[2][1] + 30)
current_after = window.after(20, b5_updater)
else:
window.after_cancel(current_after) if current_after is not None else None
p1.destroy()
p2.destroy()
page[5]["plt_wid"].place_forget()
page[5]["pl1"].remove()
page[5]["plt_wid"].destroy()
print("Closed B5 Successfully")
Tried .remove, .destroy, .place_forget on multiple items including the Canvas in tkinter, the graph still stayed there.

Answer 1

If you want to completely remove the tkinter widget the following works:
pltwidget.get_tk_widget().destroy()
If you just want to clear the figure, use:
fig.clear()
Both options work for me. You could test it in isolation for yourself by trying these options before the return value of def plot_box_1().
