When working with the Makie package in Julia, you may come across the need to switch between several layouts. This can be useful when you want to compare different visualizations or display different aspects of your data. In this article, we will explore three different ways to achieve this in Makie.
Option 1: Using the `layout` function
The first option is to use the `layout` function provided by Makie. This function allows you to define a grid layout and assign different plots to each cell of the grid. Here’s an example:
using Makie
# Create some sample data
x = 1:10
y1 = rand(10)
y2 = rand(10)
y3 = rand(10)
# Create the plots
plot1 = lines(x, y1)
plot2 = scatter(x, y2)
plot3 = histogram(y3)
# Define the layout
layout = @layout [a b; c]
# Assign plots to the layout cells
l = layout(scene, plot1, plot2, plot3)
# Display the layout
display(l)
In this example, we create three different plots (`plot1`, `plot2`, and `plot3`) and assign them to the layout cells `a`, `b`, and `c` respectively. The resulting layout is then displayed using the `display` function.
Option 2: Using subplots
Another option is to use subplots in Makie. Subplots allow you to create multiple plots within a single figure and arrange them in a grid-like fashion. Here’s an example:
using Makie
# Create some sample data
x = 1:10
y1 = rand(10)
y2 = rand(10)
y3 = rand(10)
# Create the subplots
fig, (ax1, ax2, ax3) = subplots(1, 3)
# Plot data on each subplot
lines!(ax1, x, y1)
scatter!(ax2, x, y2)
histogram!(ax3, y3)
# Display the subplots
display(fig)
In this example, we create three subplots (`ax1`, `ax2`, and `ax3`) within a single figure. We then plot the data on each subplot using the corresponding plotting functions (`lines!`, `scatter!`, and `histogram!`). Finally, we display the figure using the `display` function.
Option 3: Using multiple scenes
The third option is to use multiple scenes in Makie. Each scene can contain one or more plots, and you can switch between scenes to display different layouts. Here’s an example:
using Makie
# Create some sample data
x = 1:10
y1 = rand(10)
y2 = rand(10)
y3 = rand(10)
# Create the scenes
scene1 = Scene()
scene2 = Scene()
scene3 = Scene()
# Create the plots for each scene
plot1 = lines!(scene1, x, y1)
plot2 = scatter!(scene2, x, y2)
plot3 = histogram!(scene3, y3)
# Display the initial scene
display(scene1)
# Switch between scenes
function switch_scene(scene)
current_scene = current_backend().scene
if current_scene !== scene
current_backend().scene = scene
end
end
# Example usage
switch_scene(scene2)
In this example, we create three scenes (`scene1`, `scene2`, and `scene3`) and create the corresponding plots within each scene. We then define a `switch_scene` function that allows us to switch between scenes by setting the current scene of the backend. Finally, we display the initial scene (`scene1`) and use the `switch_scene` function to switch to `scene2`.
After exploring these three options, it is clear that using the `layout` function is the most straightforward and intuitive way to switch between several layouts in Makie. It allows you to define a grid layout and assign plots to each cell of the grid, making it easy to organize and compare different visualizations. Therefore, option 1 is the recommended approach for switching between layouts in Makie.
