Python | XlsxWriterモジュールを使用して面グラフをExcelシートにプロットする

前提条件:Excelファイルを作成して書き込む XlsxWriterはPythonライブラリであり、これを使用してExcelファイルに対して作成、書き込み、算術演算、グラフのプロットなどの複数の操作を実行できます。リアルタイムデータを使用してさまざまなチャートをプロットする方法を見てみましょう。 チャートは、少なくとも1つの一連の1つ以上のデータポイントで構成されています。系列自体はセル範囲への参照で構成されています。 チャートをExcelシートにプロットするには、まず、特定のチャートタイプのチャートオブジェクト(面積、積み上げ面積、積み上げ面積率など)を作成します。チャートオブジェクトを作成したら、そこにデータを挿入し、最後にシートオブジェクトにそのチャートオブジェクトを追加します。 コード#1:単純な面グラフを描く 簡単な面グラフをExcelシートにプロットするには、ブックオブジェクトのtype 'area'キーワード引数を指定してadd_chart()メソッドを使用します。
