如何使用 matplotlib 调整 PySimpleGUI 画布的大小

如何解决如何使用 matplotlib 调整 PySimpleGUI 画布的大小

我正在尝试更改条形图的大小，但遇到了一些困难。这些条形图从我的数据中正确绘制，但是当我调整 size 参数时画布的大小没有增加。我没有收到任何错误，所以我不确定我错过了什么。

    # define the window layout
    layoutMain = [[sg.Text('Member Access')],[sg.Menu(mainmenu_def,pad=(0,0))],[sg.Button('Store To Inventory',size = (17,1)),sg.Button('Retrieve From Inventory',sg.Button('Inventory Details',sg.Button('Exit to Home',button_color = '#36454f',1))],[sg.Text('E-Stock',font='Any 18')],[sg.Canvas(size=(100,100),key='-CANVAS-')]]
    windowMain = sg.Window('E-Stock',layoutMain,no_titlebar=False,size=(1000,600),finalize=True,resizable=True)
    windowMain.maximize()

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

解决方法

这是示例，我通过 matplolib 图中的 sg.Canvas 和 dpi 定义 figsize 的大小。

import numpy as np
import matplotlib
import matplotlib.pyplot as plt
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
import PySimpleGUI as sg


matplotlib.use('TkAgg')
w,h = figsize = (5,3)     # figure size
fig = matplotlib.figure.Figure(figsize=figsize)
dpi = fig.get_dpi()
size = (w*dpi,h*dpi)       # canvas size
t = np.arange(0,3,.01)
fig.add_subplot(111).plot(t,2 * np.sin(2 * np.pi * t))

def draw_figure(canvas,figure):
    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

layout = [[sg.Text('Plot test')],[sg.Canvas(size=size,key='-CANVAS-')],[sg.Button('Ok')]]

window = sg.Window('Embedding Matplotlib',layout,finalize=True,element_justification='center',font='Helvetica 18')
fig_canvas_agg = draw_figure(window['-CANVAS-'].TKCanvas,fig)

event,values = window.read()

window.close()
