Я создаю графический интерфейс с Tkinter и ttk и использую matplotlib для создания интерактивных графиков - опять же, как это делают миллионы других людей. Хотя большинство проблем, с которыми я сталкивался до сих пор, хорошо документированы, эта проблема кажется редкой:

При построении в 3D и настройке масштаба оси с помощьюset_lim() После команд, построенная линия превышает систему координат, что выглядит не очень хорошо. Кроме того, я не доволен кадром, который кажется немного маленьким. Вот пример:

# Missmatch.py
"""Graphical User Interface for plotting the results
calculated in the script in Octave"""

# importing libraries
import matplotlib, ttk, threading
matplotlib.use('TkAgg')
import numpy as nm
import scipy as sc
import pylab as pl
import decimal as dc
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
from matplotlib.figure import Figure
from mpl_toolkits.mplot3d import Axes3D
from oct2py import octave as oc
import Tkinter as tki

class CS:
    """CS - Controlset. This part creates the GUI with all important
    Elements. Major changes and calculations will be executed 
    in the Calculation-Class in a seperate thread. This prevents the 
    GUI from hanging"""

    def __init__(self,parent):
        """Building the main GUI"""

        ### Entire Window
        # Mainframe that contains everything.

        # Pack manager to expand the mainframe as the windowsize changes.
        self.main.pack(fill=tki.BOTH, expand=tki.YES)

        # cell grows if the users expands the window.

Просто запустите код и нажмите кнопку «SET». Здесь моя проблема.
