Infoga en sparkline
Sparkline är en liten diagram i en kalkylbladscell som ger en visuell representation av data. Använd sparklines för att visa trender i en serie värden, såsom säsongsbetonade ökningar eller minskningar, ekonomiska cykler, eller för att framhäva maximala och minimala värden. Placera en sparkline nära sina data för störst effekt. Det finns tre typer av Sparkline: Linje, Kolumn och Staplad.
Det är enkelt att skapa en sparkline med Aspose.Cells med följande exempelkoder:
