Get an array of the number of post per year of a custom post type (WordPress)

I have a custom post type called "papers", and, to feed a chart, I need an array of the number of posts per year that have posts.

I’ve tried with wp_count_posts() but it just give me the total number of post types, and get_archives() is just to static, and I need to use specific information like the number of post per year.

Does anyone know how to do this? Hope you can help me.

    For anyone who has been wondering the same thing, I got it from other forum:

    I have created a basic example on how you could achieve this result.

    // get all posts from our CPT no matter the status
$posts = get_posts([
    'post_type'      => 'papers', // based on the post type from your qeustion
    'post_status'    => 'all',
    'posts_per_page' => -1
]);

// will contain all posts count by year
// every year will contain posts count by status (added as extra =])
$posts_per_year = [];

// start looping all our posts
foreach ($posts as $post) {
    // get the post created year
    $post_created_year = get_the_date('Y', $post);

    // check if year exists in our $posts_per_year
    // if it doesn't, add it
    if (!isset($posts_per_year[$post_created_year])) {
        // add the year, add the posts stauts with the initial amount 1 (count)
        $posts_per_year[$post_created_year] = [
            $post->post_status => 1
        ];
    // year already exists, "append" to that year the count
    } else {
        // check if stauts already exists in our year
        // if it exist, add + 1 to the count
        if (isset($posts_per_year[$post_created_year][$post->post_status])) {
            $posts_per_year[$post_created_year][$post->post_status] += 1;
        // it doesnt exist, add the post type to the year with the inital amount 1 (count)
        } else {
            $posts_per_year[$post_created_year][$post->post_status] = 1;
        }
    }
}

    To get posts published from last year

    $today = getdate();
$args = array(
    'post_type' => 'post',
    'posts_per_page' => -1,
    'date_query' => array(
        array(
            'year'  => $today['year'] - 1,
        ),
    ),
);
$result = new WP_Query($args);
$count = $result->found_posts;
echo $count;

    Other different ways

    $args = array(
    'type'              => 'yearly',
    'post_type'         => 'post',
    'show_post_count'   => true
);
wp_get_archives($args);

    This will output the following
    2015 (5)
    2014 (3)
    2011 (10)
