رسم بياني للأسطورة

موضع الأسطورة

كي تحدد خصائص الأسطورة. يرجى اتباع الخطوات أدناه:

في المثال الموضح أدناه، قمنا بتعيين الموضع والحجم لأسطورة الرسم البياني.

	// Set Legend Properties
	chart->get_Legend()->set_X ( 50 / chart->get_Width());
	chart->get_Legend()->set_Y ( 50 / chart->get_Height());
	chart->get_Legend()->set_Width ( 100 / chart->get_Width());
	chart->get_Legend()->set_Height ( 100 / chart->get_Height());

	// Write the presentation file to disk
	pres->Save(outPath, Aspose::Slides::Export::SaveFormat::Pptx);
