When working with Julia, it is common to generate plots using the Plots package. However, sometimes we may want to clean the plots without closing the Julia environment. In this article, we will explore three different ways to achieve this.
Option 1: Using the `close` function
The simplest way to clean plots in Julia is by using the `close` function. This function closes the current plot window, effectively cleaning the plot. Here is an example:
using Plots
# Generate a plot
plot([1, 2, 3], [4, 5, 6])
# Clean the plot
close()
This code will generate a plot with three points and then clean the plot by closing the plot window. However, it is important to note that this method will close all plot windows, so if you have multiple plots open, they will all be closed.
Option 2: Using the `gui` backend
If you want to clean a specific plot without closing all plot windows, you can use the `gui` backend. The `gui` backend allows you to interact with individual plots and clean them without affecting other plots. Here is an example:
using Plots
# Set the backend to gui
gr(backend = :gui)
# Generate a plot
plot([1, 2, 3], [4, 5, 6])
# Clean the plot
gui(plot(1, 1, legend = false))
This code sets the backend to `gui`, generates a plot, and then cleans the plot by creating a new plot with no data and no legend. This effectively cleans the plot without closing the plot window.
Option 3: Using the `display` function
Another way to clean plots in Julia is by using the `display` function. The `display` function allows you to update the content of a plot without closing the plot window. Here is an example:
using Plots
# Generate a plot
p = plot([1, 2, 3], [4, 5, 6])
# Clean the plot
display(plot(1, 1, legend = false))
This code generates a plot and then cleans the plot by updating it with a new plot that has no data and no legend. The `display` function allows you to update the plot without closing the plot window.
After exploring these three options, it is clear that the best option depends on the specific use case. If you want to clean all plot windows, the `close` function is the simplest and most straightforward option. If you want to clean a specific plot without affecting other plots, the `gui` backend or the `display` function can be used. Ultimately, the choice depends on the specific requirements of your project.
