How do i wait for a plots jl window to be closed

When working with Julia, you may come across situations where you need to wait for a plots jl window to be closed before proceeding with the rest of your code. This can be particularly useful when you want to display a plot and then perform some calculations or analysis based on the user’s interaction with the plot.

Option 1: Using the `wait` function

One way to wait for a plots jl window to be closed is by using the `wait` function from the `Plots` package. This function blocks the execution of your code until the plot window is closed by the user.

using Plots

# Create your plot
plot(x, y)

# Wait for the plot window to be closed
wait()

This approach is simple and straightforward. However, it may not be suitable if you need to perform other tasks while waiting for the plot window to be closed.

Option 2: Using a while loop

If you need to perform other tasks while waiting for the plot window to be closed, you can use a while loop to continuously check if the plot window is still open. Once the window is closed, the loop will exit and your code can proceed.

using Plots

# Create your plot
plot(x, y)

# Check if the plot window is still open
while isopen(Plots.backend())
    # Perform other tasks
    # ...
end

This approach allows you to perform additional tasks while waiting for the plot window to be closed. However, it may consume unnecessary computational resources if the plot window remains open for a long time.

Option 3: Using the `display` function

Another option is to use the `display` function from the `Plots` package. This function displays the plot and returns a handle to the plot window. You can then use this handle to check if the window is still open and wait for it to be closed.

using Plots

# Create your plot and get the handle to the plot window
handle = display(plot(x, y))

# Wait for the plot window to be closed
while isopen(handle)
    # Perform other tasks
    # ...
end

This approach combines the benefits of the previous two options. It allows you to perform additional tasks while waiting for the plot window to be closed and avoids unnecessary resource consumption.

Overall, the best option depends on your specific use case. If you only need to wait for the plot window to be closed and don’t have any other tasks to perform, using the `wait` function is the simplest approach. However, if you need to perform other tasks or want more control over the waiting process, using a while loop or the `display` function may be more suitable.
