This article mainly introduces the example analysis of the integration of matplotlib and tkinter, which has a certain reference value, and interested friends can refer to it. I hope you will gain a lot after reading this article.

Matplotlib is the most general library in the drawing field, which is powerful and friendly with other systems, such as Python's built-in drawing module tkinter. The main goal is to achieve a case of interactive drawing using tkinter integrated matplotlib.

The tkinter module design is simplified to meet some small GUI designs, first create a form object, add basic components such as Label,Button,Radiobutton, etc., and then pack or grid components to the parent container.

In this case, the code for creating the tkinter window and components is as follows:

Window = tk.Tk ()

# step 2, name the visualization of the window

Window.title ('My Window')

# step 3, set the size of the window (length * width)

# the multiplication here is small x

Window.geometry ('1200x600')

# step 4, create a label label on the graphical interface to display and place

# define a var to associate the value of radiobutton with the value of Label.

Var = tk.StringVar ()

L = tk.Label (window, bg='yellow', width=30, height=3

Text='matplotlib in tkinter', font= ('Arial', 21))

L.pack ()

Create a basic form above, on which the Radiobutton component is created, whose parent form is a window object.

Then create a frame object and populate it with two more frame objects, one on the left and the other on the right: # layer 2 frame, left frame, growing on the main frame

Frame_l = tk.Frame (frame)

# layer 2 frame, right frame, growing on the main frame

Frame_r = tk.Frame (frame)

Frame_l.pack (side='left')

Frame_r.pack (side='right')

Then, create a bar chart in the left frame and a pie chart in the right frame.

Here is the most important part of tkinter and matplotlib integration. Matplotlib provides FigureCanvasTkAgg objects and requires only three lines of code to draw graphics in tkinter's Canvas: canvas_l = FigureCanvasTkAgg (figure_l, frame_l)

# replace with draw

Canvas_l.draw ()

Canvas_l.get_tk_widget () .pack ()

The first line of code realizes the establishment of the relationship between the figure object (matplotlib object) and the frame object (tkinter component). The second line draws using the draw method in the integrated object, and finally gets the tkinter component and assembles it into tkinter.

The final display effect is as follows:

In the interactive section, when the bar option in Radiobutton is selected, only the bar chart is displayed:

When the pie option is selected, only the pie chart is displayed:

When the both option is selected, restore the full display.

Thank you for reading this article carefully. I hope the article "sample Analysis of the Integration of matplotlib and tkinter" shared by the editor will be helpful to you.
