How to display a graph using tkinter?-CodePudding

How can I click on the GUI button to display the graph that I have coded?

from tkinter import *

root = Tk()
frame = Frame(root)
frame.pack()
bottomframe = Frame(root)
bottomframe.pack(side=BOTTOM)
redbutton = Button(frame, text='Training 1', fg='red')
redbutton.pack(side=LEFT)
greenbutton = Button(frame, text='Training 2', fg='brown')
greenbutton.pack(side=LEFT)
bluebutton = Button(frame, text='Testing 1', fg='blue')
bluebutton.pack(side=LEFT)
blackbutton = Button(bottomframe, text='Testing 2', fg='black')
blackbutton.pack(side=BOTTOM)
root.mainloop()

Based on the code above, there are 4 buttons display in the graphical user interface. I would like to press on the Training 1 button to display my graph below.

""" Plot """
plt.plot(scores_train, 'b')
plt.title('Model Accuracy')
plt.xlabel('Epoch')
plt.ylabel('Accuracy')
plt.legend(['train'], loc='upper left')
plt.show()

CodePudding user response：

You need to import pyplot from matplotlib and then define the function for plotting the graph. Suppose we call the function 'graph', it would look like this:

def graph():
   plt.plot(scores_train, 'b')
   plt.title('Model Accuracy')
   plt.xlabel('Epoch')
   plt.ylabel('Accuracy')
   plt.legend(['train'], loc='upper left')
   plt.show()

Then you need to add the command for the redbutton, like this:

redbutton = Button(frame, text='Training 1', command=graph, fg='red')

Hope this works for you!
