Python - How to maximize a plt.show() window

To maximize a plt.show() window in Matplotlib, you can use the manager module of the matplotlib library to get the figure manager and then call its full_screen_toggle() method. Here's an example:

import matplotlib.pyplot as plt from matplotlib import get_backend # Create a sample plot plt.plot([1, 2, 3, 4], [10, 20, 25, 30]) # Get the current figure fig = plt.gcf() # Get the backend to determine if it is interactive backend = get_backend().lower() # Maximize the window for interactive backends if backend in {'tkagg', 'wxagg', 'qt4agg', 'qt5agg', 'gtk3agg'}: manager = fig.canvas.manager manager.full_screen_toggle() # Show the plot plt.show()

This example checks the backend of Matplotlib and maximizes the window if the backend is interactive (e.g., Tkinter, PyQt, etc.).

Keep in mind that the behavior may vary based on the backend being used. This example covers some common interactive backends. If you encounter issues with a specific backend, you may need to adjust the code accordingly.

If you are using a non-interactive backend, you might want to consider saving the plot to an image file with the desired size instead of maximizing the window.

Examples

  1. "Matplotlib maximize plot window in Python"

    • Code Implementation:
      import matplotlib.pyplot as plt plt.plot([1, 2, 3, 4]) plt.show(block=False) mng = plt.get_current_fig_manager() mng.window.state('zoomed') plt.show()
    • Description: Creates a simple plot, maximizes the plot window, and shows the plot.

  2. "Matplotlib fullscreen plot display in Python"

    • Code Implementation:
      import matplotlib.pyplot as plt plt.plot([1, 2, 3, 4]) mng = plt.get_current_fig_manager() mng.full_screen_toggle() plt.show()
    • Description: Creates a plot and toggles the fullscreen display of the plot window.

  3. "Maximize Matplotlib figure window programmatically"

    • Code Implementation:
      import matplotlib.pyplot as plt fig, ax = plt.subplots() fig.canvas.manager.window.showMaximized() plt.show()
    • Description: Creates a figure, maximizes its window programmatically, and displays the plot.

  4. "Matplotlib plot window size adjustment in Python"

    • Code Implementation:
      import matplotlib.pyplot as plt plt.plot([1, 2, 3, 4]) mng = plt.get_current_fig_manager() mng.resize(*mng.window.maxsize()) plt.show()
    • Description: Adjusts the plot window size to the maximum allowed size.

  5. "Maximize Matplotlib figure window on specific backend"

    • Code Implementation:
      import matplotlib.pyplot as plt from matplotlib import backend_tools plt.switch_backend("TkAgg") # Use the appropriate backend plt.plot([1, 2, 3, 4]) mng = plt.get_current_fig_manager() mng.window.state('zoomed') plt.show()
    • Description: Switches the backend to TkAgg (or the appropriate backend) and maximizes the plot window.

  6. "Matplotlib window fullscreen on specific monitor"

    • Code Implementation:
      import matplotlib.pyplot as plt from matplotlib import backend_tools plt.switch_backend("TkAgg") # Use the appropriate backend plt.plot([1, 2, 3, 4]) mng = plt.get_current_fig_manager() mng.window.wm_attributes('-fullscreen', 'true') plt.show()
    • Description: Switches the backend to TkAgg (or the appropriate backend) and makes the plot window fullscreen on the specified monitor.

  7. "Maximize Matplotlib figure window using Qt backend"

    • Code Implementation:
      import matplotlib.pyplot as plt from PyQt5.QtWidgets import QApplication plt.switch_backend("Qt5Agg") # Use the appropriate backend plt.plot([1, 2, 3, 4]) mng = plt.get_current_fig_manager() mng.window.showMaximized() plt.show() QApplication.instance().exec_()
    • Description: Switches the backend to Qt5Agg (or the appropriate backend) and maximizes the plot window.

  8. "Matplotlib maximize plot window on Mac"

    • Code Implementation:
      import matplotlib.pyplot as plt from matplotlib import backend_tools plt.switch_backend("MacOSX") # Use the appropriate backend plt.plot([1, 2, 3, 4]) mng = plt.get_current_fig_manager() mng.full_screen_toggle() plt.show()
    • Description: Switches the backend to MacOSX (or the appropriate backend) and toggles fullscreen display.

  9. "Matplotlib maximize window on Windows"

    • Code Implementation:
      import matplotlib.pyplot as plt from matplotlib import backend_tools plt.switch_backend("TkAgg") # Use the appropriate backend plt.plot([1, 2, 3, 4]) mng = plt.get_current_fig_manager() mng.window.state('zoomed') plt.show()
    • Description: Switches the backend to TkAgg (or the appropriate backend) and maximizes the plot window on Windows.

  10. "Matplotlib maximize figure window with key press event"

    • Code Implementation:
      import matplotlib.pyplot as plt from matplotlib.backend_bases import key_press_handler fig, ax = plt.subplots() fig.canvas.mpl_connect('key_press_event', key_press_handler) plt.plot([1, 2, 3, 4]) plt.show()
    • Description: Connects a key press event handler to the figure canvas, allowing for key presses to maximize the plot window.
