在 Tkinter 中显示 sns 热图

Question

在 Tkinter GUI 中，我有三个 Entry 小部件，用于将数字输入到嵌套的 for 循环中，该循环创建一个数组，用于在点击“提交”按钮后创建 seaborn 热图。 Entry 小部件位于框架中，我想在框架下方的 GUI 窗口中绘制热图。我可以创建绘图轴，但热图不显示。任何建议将不胜感激。

`import random

def HPS(x,y,z): #HPS Function
    NUMX = int(x.get()) # No. of columns (x)
    NUMY = int(y.get()) # No. rows (y)
    NUMZ = int(z.get())# No. of levels (z)
    
    z = np.zeros((NUMZ)) # define number of levels
    conc = np.zeros((NUMZ, NUMY, NUMX)) #Create 3d conc array (z,y,x)

    for z in range(NUMZ):
      for y in range(NUMY):
         for x in range(NUMX):
             c = round(random.uniform(0.0, 1.0) ,2)
             conc[z,y,x] = c      # fill array with for loops
                 
    conc_sum = conc.sum(axis=0) # add the two z-levels together
    print(conc_sum)
    df_sum = pd.DataFrame(conc_sum) # Create dataframe of sum_conc array

    #Create heatmap and plot in Tkinter
    figure = Figure(figsize=(4, 4))
    ax = figure.subplots()
    sns.heatmap(df_sum,cmap='RdBu') # Create heatmap
    plt.ylim(0,NUMY) # Reverse y-axis coordinates   
    
    # Plot heatmap in Tkinter
    canvas = FigureCanvasTkAgg(figure, master=root)
    canvas.draw()
    canvas.get_tk_widget().grid(row =8, column=0, columnspan=3)
           
# HPS Tkinter GUI
root.geometry("400x400") # Set sizeof GUI
frame1 = Frame(root) #Create fame for input boxes   
frame1=LabelFrame(root, text='Frame 1', padx=10, pady=10)
frame1.grid(row=0, column=0)

#Create input boxes and labels
label1 = Label(frame1, text='NUMX = ') 
label1.grid(row=0, column=0)
label2 = Label(frame1, text='NUMY = ') 
label2.grid(row=1, column=0)
label3 = Label(frame1, text='NUMZ = ') 
label3.grid(row=2, column=0)

#Enter data
x = Entry(frame1)    
y = Entry(frame1)
z = Entry(frame1)
x.grid(row=0, column = 2)
y.grid(row=1, column = 2)
z.grid(row=2, column = 2)

#Create submit button and call HPS function
myButton = Button(root, text='Submit', command = lambda:HPS(x,y,z))
myButton.grid(row = 5, column = 2)

root.mainloop()`

我按照不同论坛的建议尝试了各种不同的 Tkinter 代码来显示绘图

Answer 1

HPS 函数中的以下代码更改创建了热图

'#Create heatmap and plot in Tkinter
figure = Figure(figsize=(4, 4))
ax = figure.add_subplot(111)
sns.heatmap(df_sum,ax=ax,cmap='RdBu') # Create heatmap
plt.ylim(0,NUMY) # Reverse y-axis coordinates
canvas = FigureCanvasTkAgg(figure, master=root)
canvas.draw()
canvas.get_tk_widget().grid(row =8, column=0, columnspan=3)'
