Code for reproduction

def draw_diagram():
    width = 0.4  # Задаём ширину столбцов
    fig, ax = plt.subplots(figsize=(14, 5), layout='constrained')
    ax.bar(labels, cowered_data, width, label='Процент покрытых мер-измерений тестами')
    ax.bar(labels, uncowered_data, width, bottom=cowered_data,
           label='Процент непокрытых мер-измерений тестами')
    ax.set_ylabel('% покрытия')
    ax.set_title('Процент покрытия кубов тестами')
    ax.legend()
    plt.savefig('diagram.png')
