Creating an Image Viewer with PySimpleGUI - Mouse Vs Python

Temporary files to display later

teach me how to plot something using plotly, then save it as a temporary file using 'tempfile' library, then read that temporary file and display the image in a PySimpleGUI. All of this in python

Certainly! I can guide you through the process of plotting using Plotly, saving the plot as a temporary file using the tempfile library, and displaying the image in PySimpleGUI. Here's a step-by-step guide:

Step 1: Install the necessary libraries

First, make sure you have the required libraries installed. You can install them using pip:

pip install plotly PySimpleGUI

Step 2: Import the libraries

Next, import the necessary libraries in your Python script:

import plotly.graph_objects as go
import tempfile
import PySimpleGUI as sg

Step 3: Create and save the plot as a temporary file Now, let's create a simple plot using Plotly and save it as a temporary file using the tempfile library:

# Create a sample plot
fig = go.Figure(data=go.Bar(x=[1, 2, 3], y=[4, 5, 6]))

# Generate a temporary file path
temp_file_path = tempfile.NamedTemporaryFile(suffix=".html").name

# Save the plot as an HTML file
fig.write_html(temp_file_path)

In this example, we created a bar plot using Plotly and saved it as an HTML file with a .html extension. The NamedTemporaryFile function from the tempfile library helps us generate a temporary file path.

Step 4: Display the image in PySimpleGUI

Finally, let's use PySimpleGUI to display the image:

# Define the layout of the GUI
layout = [[sg.Image(temp_file_path)]]

# Create the GUI window
window = sg.Window("Plot Viewer", layout)

# Event loop to handle GUI events
while True:
    event, values = window.read()
    if event == sg.WINDOW_CLOSED:
        break

# Close the window
window.close()

In this code, we define the layout of the GUI window, which consists of a single sg.Image element displaying the temporary file. We create the window and enter an event loop to handle GUI events. The loop continues until the window is closed.

That's it! When you run this script, it will display the plot saved in the temporary file using PySimpleGUI. Remember to replace temp_file_path with the actual path to your temporary file if you've modified it.

Note: Make sure your script has proper access rights to create temporary files and display GUI windows on your system.
