Personalize sua visualização com componentes SDK

Dica

Esta lição faz parte de um curso que ensina como construir uma visualização personalizada na plataforma New Relic.

Use as visualizações personalizadas da New Relic para exibir seus dados, sejam eles do banco de dados da New Relic ou de uma fonte externa, de maneiras exclusivas e distintas dos gráficos oferecidos pela plataforma New Relic.

Nesta lição, você criará uma visualização que exibe seus dados em um dos dois tipos de gráfico: RadarChart ou Treemap. Em seguida, você implementa um componente SegmentedControl do SDK do New Relic One, que permite alternar entre os dois tipos de gráfico. Em última análise, isso lhe dá liberdade para visualizar seus dados de uma forma dinâmica que não é possível com as ofertas básicas da New Relic.

Dica

Se você se perder no projeto de código e quiser ver como os arquivos devem ficar quando terminar cada lição, verifique o projeto do curso no Github.

Antes de você começar

Finalmente, se ainda não o fez:

Cadastre-se para uma conta New Relic
Instale o Node.js.
Conclua as etapas do início rápidonr1 para instalar e configurar a CLI

Crie sua visualização

Certifique-se de estar trabalhando com a versão mais recente da CLI do New Relic:

bash

$nr1 update

Crie uma visualização, chamada radar-or-treemap, em um Nerdpack, chamado alternate-viz:

bash

$nr1 create --type visualization --name radar-or-treemap
✔ You’re trying to create a visualization outside of a Nerdpack.  We’ll create a Nerdpack for you—what do you want to name it? … alternate-viz
✔  nerdpack created successfully!
   nerdpack alternate-viz is available at "./alternate-viz"
✔  visualization created successfully!
   visualization radar-or-treemap is available at "./alternate-viz/visualizations/radar-or-treemap"

Dica

Se você receber um RequestError para um certificado autoassinado ao executar nr1 create, talvez seja necessário adicionar um certificado à cadeia de certificados do Node.

Como resultado, você tem um novo diretório visualizations/radar-or-treemap em alternate-viz:

bash

$cd alternate-viz
$ls visualizations/radar-or-treemap

Este valor state armazena o tipo de gráfico no qual você deseja mostrar seus dados.

Agora que você criou um objeto que enumera as opções de tipo de gráfico para sua visualização e inicializou state.selectedChart, você está pronto para implementar uma interface de controle para alternar entre os dois tipos de gráfico.

Adicionar `SegmentedControl` componentes

state.selectedChart não é útil a menos que o usuário da sua visualização possa realmente selecionar um tipo de gráfico. Use SegmentedControl e SegmentedControlItem para alternar entre os dois tipos de gráfico.

Importe SegmentedControl e SegmentedControlItem de nr1:

Aqui, seu SegmentedControl registra o SegmentedControlItem.value no console quando você altera sua seleção. Os valores definidos para seus componentes SegmentedControlItem correspondem aos dois CHART_TYPES criados em uma etapa anterior.

Navegue até a raiz do seu Nerdpack em alternate-viz.

Sirva seu Nerdpack localmente:

bash

$nr1 nerdpack:serve

Abra o link para sua visualização que é mostrada no terminal quando o servidor Node é iniciado:

bash

Visualizations:
 ⁎  radar-or-treemap https://one.nr/012ab3cd4Ef

Configure sua visualização com um ID de conta e uma consulta.

Com alguns dados necessários para o processamento do seu gráfico, agora você verá um RadarChart com o SegmentedControl na parte superior da visualização.

Olhe no console do seu browser para ver seu log SegmentedControl .

Conecte `state` do seu componente ao `SegmentedControl`

Adicione um método para atualizar state e conecte esse método ao SegmentedControl adicionado na última seção.

Adicione um método de componente, chamado updateSelectedChart():

Agora, quando você alterar sua seleção em SegmentedControl, sua seleção será definida em state.

Implementar uma opção `Treemap`

Adicione um Treemap à sua visualização. Este mapa será uma alternativa ao RadarChart existente.

Detalhe técnico

Este guia usa componentes Recharts para gráficos de terceiros, mas você pode usar qualquer outra biblioteca de gráficos JavaScript que seja compatível com a versão atual do React ao criar visualizações e aplicativos New Relic.

Importe Treemap de recharts:

visualizations/radar-or-treemap/index.js

Aqui, você definiu um novo componente Treemap com alguns adereços, incluindo height, width, fill e stroke.

Com seu Nerdpack servido localmente, visualize sua visualização. Os SegmentedControl e RadarChart estão na parte superior da visualização, mas se você rolar para baixo, verá seu novo Treemap.

Alterne entre gráficos com o seu componente `state`

Use state.selectedChart para determinar qual gráfico mostrar: o RadarChart ou o Treemap.

Desestruture this.state para acessar selectedChart como uma constante separada. Em seguida, compare selectedChart com CHART_TYPES.Radar. Se forem iguais, renderize um RadarChart. Caso contrário, renderize um Treemap:

Aqui, você usou uma expressão ternária para renderizar um RadarChart ou um Treemap. O gráfico renderizado é determinado pelo valor de selectedChart.

Com seu Nerdpack servido localmente, visualize sua visualização.

Selecione Radar chart em SegmentedControl.

Selecione o Treemap chart em SegmentedControl.

Resumo

Parabéns! Nesta lição, você aprendeu como:

Personalize sua visualização usando componentes do SDK do New Relic One
