إنشاء رسم بياني دائري مع خطوط الريادة

يشرح هذا المقال كيفية إنشاء مخطط دائري مع خطوط قيادية من الصفر باستخدام API الخاص بـ Aspose.Cells للبايثون via .NET. في Excel، يتم تعيين خيار ‘عرض الخطوط القيادية’ بشكل افتراضي، لذلك عند إنشاء رسم دائري في Excel، تظهر الخطوط القيادية. ومع ذلك، أثناء إنشاء مخطط مماثل باستخدام API الخاص بـ Aspose.Cells للبايثون via .NET، يجب تعيين الخاصية Series.has_leader_lines بشكل صريح.
لعرض كيفية استخدام API الخاص بـ Aspose.Cells للبايثون via .NET لإنشاء مخطط دائري مع خطوط قيادية، سنبدأ بإنشاء Workbook جديد وإدخال بعض البيانات التي ستعمل كمصدر بيانات السلسلة. بمجرد وضع البيانات، سنضيف Chart من نوع ChartType.PIE إلى مجموعة الرسوم البيانية ونقوم بضبط خصائصها المختلفة للحصول على العرض المطلوب للرسم.

حتى الآن قمنا بإنشاء رسم بياني دائري وضبط جوانبه المختلفة. الآن سنقوم بتشغيل خطوط الريادة للرسم البياني. يرجى ملاحظة أنه لعرض خطوط الريادة، علينا نقل تسميات البيانات قليلاً.
يقوم الكود التالي بتشغيل خطوط الريادة، يحدث الرسم البياني، ومن ثم يحسب مواقع تسميات البيانات لنقلها وفقًا لذلك.
