[Matplotlib-users] tk and matplotlib

Community matplotlib-users

hi
i am creating a matplotlib draw (musical sales on a guitar) in function of some parameters (tonic note, type of gamme or chord…)
i am now creating tk radio buttons so that the user can choose the parameters
i can get these parameters and create the matplotlib picture with them
but the matplotlib will open a different window
would it be possible to have a same window, divided as a table, with at the lift the radio buttons, and at the right the matplotlib result ?

Hi Anthony
hi everyone
i feel blocked at the just beginning of my attempts with PySimpleGUI/MatPlotLib
with exactly your code i get this answer :
i dont know in which direction to search :

When I want to embed an MPL plot inside of a tkinter window I use PySimpleGUI. It’s a quick and easy module that makes working with tkinter much more manageable. I’ve found an example that uses PySimpleGui and embeds a simple MPL plot inside. I hope this helps. Happy coding!

#!/usr/bin/env python
import PySimpleGUI as sg
import matplotlib
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
# matplotlib.use('TkAgg')
import numpy as np
import matplotlib.pyplot as plt
"""
Demonstrates one way of embedding Matplotlib figures into a PySimpleGUI window.
Paste your Pyplot code into the section marked below.
Do all of your plotting as you normally would, but do NOT call plt.show().
Stop just short of calling plt.show() and let the GUI do the rest.
The remainder of the program will convert your plot and display it in the GUI.
If you want to change the GUI, make changes to the GUI portion marked below.
"""

import matplotlib.pyplot as plt
import numpy as np

def abline(slope, intercept):
    """Plot a line from slope and intercept"""
    axes = plt.gca()
    x_vals = np.array(axes.get_xlim())
    y_vals = intercept + slope * x_vals
    plt.plot(x_vals, y_vals, '--')

# ------------------------------- PASTE YOUR MATPLOTLIB CODE HERE -------------------------------

abline(-0.3, 1)
plt.ylim(0.5, 1.5)
plt.xlim(0,1)

# ------------------------------- END OF YOUR MATPLOTLIB CODE -------------------------------

# ------------------------------- Beginning of Matplotlib helper code -----------------------

def draw_figure(canvas, figure, loc=(0, 0)):
    figure_canvas_agg = FigureCanvasTkAgg(figure, canvas)
    figure_canvas_agg.draw()
    figure_canvas_agg.get_tk_widget().pack(side='top', fill='both', expand=1)
    return figure_canvas_agg

# ------------------------------- Beginning of GUI CODE -------------------------------

fig = plt.gcf() # if using Pyplot then get the figure from the plot
figure_x, figure_y, figure_w, figure_h = fig.bbox.bounds

# define the window layout
layout = [[sg.Text('Plot test', font='Any 18')],
          [sg.Canvas(size=(figure_w, figure_h), key='-CANVAS-')],
          [sg.OK(pad=((figure_w / 2, 0), 3), size=(4, 2))]]

# create the form and show it without the plot
window = sg.Window('Demo Application - Embedding Matplotlib In PySimpleGUI',
    layout, force_toplevel=True, finalize=True)

# add the plot to the window
fig_photo = draw_figure(window['-CANVAS-'].TKCanvas, fig)

# show it all again and get buttons
event, values = window.read()
