Gostaria de alterar o gráfico para mostrar que 14.047 é menor que 15, mais precisão decimal

Você pode alterar a altura do gráfico e os limites do eixo y para "ampliar" os dados. Fiz o gráfico com 18cm de altura, com ymin=8,5 e ymax=19. Isso mostra sua diferença.
No entanto, esta pode não ser a melhor solução. Dado o pequeno tamanho da diferença, você pode considerar explicar os dados em seu texto ou representá-los de forma diferente, talvez com valores no gráfico.
