Skapa cirkeldiagram med ledarlinjer

Denna artikel förklarar hur man skapar ett tårtdiagram med ledande linjer från början med Aspose.Cells för Python via .NET API. I Excel är alternativet ‘Visa ledande linjer’ inställt som standard, så när du skapar ett tårtdiagram i Excel visas ledande linjer. Men när du skapar liknande diagram med Aspose.Cells för Python via .NET API:er måste du uttryckligen ställa in Series.has_leader_lines egenskapen.
För att demonstrera användningen av Aspose.Cells för Python via .NET API för att skapa ett tårtdiagram med ledande linjer, kommer vi först att skapa en ny Workbook och mata in data som kommer att fungera som serie datakälla. När datan är på plats, lägger vi till en Chart av typ ChartType.PIE i diagramkollektionen och ställer in dess olika aspekter för att få önskat diagramutsik.

Hittills har vi skapat ett cirkeldiagram och ställt in dess olika aspekter. Nu kommer vi att slå på ledarlänkarna för diagrammet. Observera, för att visa ledarlänkar måste vi flytta dataetiketterna lite.
Följande kodsnutt slår på ledarlänkarna, uppdaterar diagrammet och beräknar sedan dataetiketternas positioner för att flytta dem på lämpligt sätt.
