Scatter plot vector of static vectors with plots

When working with scatter plots in Julia, it is common to encounter the need to plot a vector of static vectors. In this article, we will explore three different ways to solve this problem and determine which option is the best.

Option 1: Using a for loop

One way to solve this problem is by using a for loop to iterate over the vector of static vectors and plot each individual vector. Here is an example code snippet:

using Plots

function scatter_plot_vectors(vectors)
    for vector in vectors
        scatter(vector[1], vector[2])
    end
end

vectors = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
scatter_plot_vectors(vectors)

This code snippet defines a function scatter_plot_vectors that takes in a vector of static vectors and plots each individual vector using the scatter function from the Plots package. The function is then called with a sample input vector vectors.

Option 2: Using the splat operator

Another way to solve this problem is by using the splat operator to unpack the vector of static vectors and pass each individual vector as separate arguments to the scatter function. Here is an example code snippet:

using Plots

function scatter_plot_vectors(vectors)
    scatter(vectors...)
end

vectors = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
scatter_plot_vectors(vectors)

This code snippet defines a function scatter_plot_vectors that takes in a vector of static vectors and uses the splat operator ... to unpack the vector and pass each individual vector as separate arguments to the scatter function. The function is then called with a sample input vector vectors.

Option 3: Using the plot function

A third way to solve this problem is by using the plot function instead of the scatter function. The plot function can handle multiple vectors as input and automatically create a scatter plot. Here is an example code snippet:

using Plots

function scatter_plot_vectors(vectors)
    plot(vectors)
end

vectors = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
scatter_plot_vectors(vectors)

This code snippet defines a function scatter_plot_vectors that takes in a vector of static vectors and uses the plot function to create a scatter plot. The function is then called with a sample input vector vectors.

After exploring these three options, it is clear that the third option, using the plot function, is the best solution. It is more concise and eliminates the need for a for loop or the splat operator. Additionally, the plot function automatically handles multiple vectors as input, making it more versatile.
