Personalice su visualización con componentes SDK

Sugerencia

Esta lección es parte de un curso que le muestra cómo crear una visualización personalizada en la plataforma New Relic.

Emplee visualizaciones personalizadas de New Relic para mostrar sus datos, ya sea de la base de datos de New Relic o de una fuente externa, de maneras únicas que son distintas de los gráficos que ofrece la plataforma New Relic.

En esta lección, creará una visualización que muestra sus datos en uno de dos tipos de gráficos: RadarChart o Treemap. Luego, implementa un componente SegmentedControl del SDK de New Relic One, que le permite alternar entre los dos tipos de gráficos. En última instancia, esto le brinda libertad para ver sus datos de una manera dinámica que no es posible con las ofertas básicas de New Relic.

Antes de que empieces

Finalmente, si aún no lo hiciste:

Registrar para obtener una cuenta New Relic
Instalar Node.js
Complete los pasos del nr1 inicio rápido para instalar y configurar la CLI

Crea tu visualización

Cerciorar de estar trabajando con la última versión de New Relic CLI:

bash

$nr1 update

Cree una visualización, llamada radar-or-treemap, en un Nerdpack, llamado 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"

Sugerencia

Si recibe un RequestError para un certificado autofirmado cuando ejecuta nr1 create, es posible que deba agregar un certificado a la cadena de certificados de Node.

Como resultado, tiene un nuevo directorio visualizations/radar-or-treemap en alternate-viz:

bash

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

Este valor state almacena el tipo de gráfico en el que desea mostrar sus datos.

Ahora que creó un objeto que enumera las opciones de tipo de gráfico para su visualización e inicializó state.selectedChart, está listo para implementar una UI de control para cambiar entre los dos tipos de gráfico.

Agregar `SegmentedControl` componentes

Aquí, su SegmentedControl registra el SegmentedControlItem.value en la consola cuando cambia su selección. Los valores que definió para sus componentes SegmentedControlItem corresponden a los dos CHART_TYPES que creó en un paso anterior.

Navega hasta la raíz de tu Nerdpack en alternate-viz.

Sirve tu Nerdpack localmente:

bash

$nr1 nerdpack:serve

Abra el enlace a su visualización que se muestra en la terminal cuando se inicia el servidor de Node:

bash

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

Configure su visualización con un ID de cuenta y una consulta.

Con algunos datos necesarios para que su gráfico los procese, ahora verá un RadarChart con el SegmentedControl en la parte superior de la vista.

Mire la consola de su browser para ver su log SegmentedControl.

Conecte `state` de su componente al `SegmentedControl`

Agregue un método para actualizar state y conecte ese método con el SegmentedControl que agregó en la última sección.

Ahora, cuando cambie su selección en SegmentedControl, su selección se establecerá en state.

Implementar una opción `Treemap`

Agregue un Treemap a su visualización. Este mapa será una alternativa al RadarChart existente.

visualizations/radar-or-treemap/index.js

Aquí, definió un nuevo componente Treemap con algunos accesorios, incluidos height, width, fill y stroke.

Con su Nerdpack servido localmente, vea su visualización. SegmentedControl y RadarChart están en la parte superior de la vista, pero si te desplazas hacia abajo, verás tu nuevo Treemap.

Cambie entre gráficos con los de su componente `state`

Emplee state.selectedChart para determinar qué gráfico mostrar: el RadarChart o el Treemap.

Desestructura this.state para acceder a selectedChart como una constante independiente. Luego, compare selectedChart con CHART_TYPES.Radar. Si son iguales, renderice un RadarChart. De lo contrario, renderice un Treemap:

Aquí, usaste una expresión ternaria para representar un RadarChart o un Treemap. El gráfico representado está determinado por el valor de selectedChart.

Con su Nerdpack servido localmente, vea su visualización.

Seleccione Radar chart de SegmentedControl.

Seleccione el Treemap chart de SegmentedControl.
