Insérer un sparkline
Un sparkline est un petit graphique dans une cellule de feuille de calcul qui fournit une représentation visuelle des données. Utilisez les sparklines pour montrer les tendances dans une série de valeurs, telles que les augmentations ou diminutions saisonnières, les cycles économiques, ou pour mettre en évidence les valeurs maximales et minimales. Positionnez un sparkline près de ses données pour un plus grand impact. Il existe trois types de sparkline : ligne, colonne et empilée.
Il est simple de créer un sparkline avec Aspose.Cells en utilisant les codes d’exemple suivants :
