SDKコンポーネントを使用して視覚化をカスタマイズする

ヒント

このレッスンは、New Relic プラットフォームでカスタム視覚化を構築する方法を学習するコースの一部です。

New Relic のカスタム視覚化を使用すると、New Relic のデータベースからのデータでも外部ソースからのデータでも、New Relic プラットフォームが提供するチャートとは異なる独自の方法でデータを表示できます。

このレッスンでは、 RadarChartまたはTreemapの 2 つのグラフタイプのいずれかでデータを表示する視覚化を構築します。次に、New Relic One SDK からSegmentedControlコンポーネントを実装して、2 つのチャートタイプを切り替えることができるようになります。最終的に、これにより、New Relic の基本機能では不可能な動的な方法でデータを自由に表示できるようになります。

あなたが始める前に

最後に、まだ行っていない場合は、次の操作を行います。

New Relicアカウントにサインアップ
Node.jsをインストールする
nr1クイックスタートの手順を完了して、CLI をインストールして構成します。

視覚化を作成する

最新バージョンの New Relic CLI を使用していることを確認してください。

bash

$nr1 update

Nerdpack のalternate-vizに、 radar-or-treemapという視覚化を作成します。

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"

nr1 createを実行したときに自己署名証明書のRequestErrorを受け取った場合は、Node の証明書チェーンに証明書を追加する必要がある可能性があります。

その結果、 alternate-vizの下に新しいvisualizations/radar-or-treemapディレクトリが作成されます。

ここで、選択を変更すると、 SegmentedControlはSegmentedControlItem.valueをコンソールに記録します。 SegmentedControlItemコンポーネントに定義した値は、前の手順で作成した 2 つのCHART_TYPESに対応します。

alternate-vizにある Nerdpack のルートに移動します。

Nerdpack を地元で提供しましょう:

bash

$nr1 nerdpack:serve

Node サーバーの起動時にターミナルに表示される視覚化へのリンクを開きます。

bash

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

アカウント ID とクエリを使用して視覚化を構成します。

チャートの処理に必要なデータがいくつかあるため、ビューの上部にSegmentedControlを含むRadarChartが表示されます。

SegmentedControl ログを確認するには、 browserのコンソールを参照してください。

コンポーネントの`state`を `SegmentedControl`

stateを更新するメソッドを追加し、そのメソッドを前のセクションで追加したSegmentedControlに接続します。

updateSelectedChart()というコンポーネントメソッドを追加します。

ここで、 SegmentedControlで選択内容を変更すると、その選択内容がstateに設定されます。

実装する `Treemap`

視覚化にTreemapを追加します。このマップは既存のRadarChartの代替となります。

技術的詳細

このガイドでは、サードパーティのチャートにRechartsコンポーネントを使用しますが、New Relic の視覚化とアプリを構築するときに、現在の React バージョンと互換性のある他の JavaScript チャートライブラリを使用することもできます。

visualizations/radar-or-treemap/index.js

ここでは、 height 、 width 、 fill 、 strokeなどのいくつかのプロパティを使用して、新しいTreemapコンポーネントを定義しました。

Nerdpack をローカルで提供して、視覚化を表示します。 SegmentedControlとRadarChartビューの上部にありますが、下にスクロールすると新しいTreemapが表示されます。

コンポーネントのチャートを切り替える `state`

state.selectedChartを使用して、表示するグラフRadarChartまたはTreemapを決定します。

this.stateを分解して、別の定数としてselectedChartにアクセスします。次に、 selectedChartとCHART_TYPES.Radarを比較します。同じ場合は、 RadarChartをレンダリングします。それ以外の場合は、 Treemapをレンダリングします。

ここでは、三項式を使用してRadarChartまたはTreemapをレンダリングしました。レンダリングされるチャートは、 selectedChartの値によって決まります。

Nerdpack をローカルで提供して、視覚化を表示します。

SegmentedControlからRadar chart [レーダーチャート]を選択します。

SegmentedControlからTreemap chart [ツリーマップチャート]を選択します。
