Ao rastrear progress\u00e3o cont\u00ednua ou mudan\u00e7as em s\u00e9ries temporais, o Gr\u00e1fico de Linha<\/strong>serve como a ferramenta visual principal. Diferentemente dos gr\u00e1ficos de colunas ou barras discretas que se concentram em compara\u00e7\u00f5es individuais de categorias, os gr\u00e1ficos de linha enfatizam conex\u00e3o e inclina\u00e7\u00e3o para destacar momento, sazonalidade e mudan\u00e7as s\u00fabitas em m\u00e9tricas<\/em> ao longo de sequ\u00eancias ininterruptas, como o crescimento di\u00e1rio de usu\u00e1rios ativos, receita recorrente mensal ou fluxos de telemetria de sensores.<\/p>\n

Os Mecanismos dos Gr\u00e1ficos de Linha<\/h2>\n

No Apache ECharts, as visualiza\u00e7\u00f5es de linha s\u00e3o configuradas definindo a propriedade series type<\/code> para 'line'<\/code>. Os gr\u00e1ficos de linha conectam pontos de dados ordenados sequencialmente ao longo de um eixo horizontal cont\u00ednuo categ\u00f3rico ou de escala de tempo (xAxis<\/code>) e mapeiam valores num\u00e9ricos cont\u00ednuos para o eixo vertical (yAxis<\/code>).<\/p>\n

1. Configura\u00e7\u00e3o B\u00e1sica<\/h3>\n

Para criar um gr\u00e1fico de linha b\u00e1sico, defina suas categorias cont\u00ednuas ao longo do eixo X e mapeie seu conjunto de dados para um objeto s\u00e9rie com type: 'line'<\/code>:<\/p>\n

T\u00e9cnicas Estruturais Avan\u00e7adas<\/h2>\n
Os gr\u00e1ficos de linha oferecem flexibilidade para sobreposi\u00e7\u00f5es de m\u00faltiplas m\u00e9tricas, curvas de interpola\u00e7\u00e3o suave e indicadores personalizados de pontos de dados.<\/p>\n

Por padr\u00e3o, as s\u00e9ries de linha conectam pontos de dados com segmentos de linha reta. Habilitar smooth: true<\/code>aplica interpola\u00e7\u00e3o por spline c\u00fabico para criar caminhos de linha curvos e org\u00e2nicos em todo o seu conjunto de dados:<\/p>\n

Melhores Pr\u00e1ticas Estrat\u00e9gicas<\/h2>\n
    \n
  • Use boundaryGap: false<\/code> para sequ\u00eancias de tempo:<\/strong> Remover os espa\u00e7amentos padr\u00e3o nas bordas em eixos de tempo cont\u00ednuos permite que a linha comece diretamente na margem zero, proporcionando uma apresenta\u00e7\u00e3o limpa de borda a borda.<\/li>\n
  • Mantenha o n\u00famero de linhas baixo:<\/strong>Evite renderizar mais de 4 a 5 linhas em uma \u00fanica tela. Gr\u00e1ficos de linhas muito cheios (“gr\u00e1ficos de espaguete”) tornam-se rapidamente ileg\u00edveis.<\/li>\n
  • Gatilhos de Dica de Ferramenta do Eixo<\/strong> Sempre configurar tooltip: { trigger: 'axis' }<\/code>para que os usu\u00e1rios possam passar o mouse por qualquer ponto horizontal para visualizar valores precisos em todas as s\u00e9ries de linhas ativas simultaneamente.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
