[ABAP] Charts mit cl_gui_chart_engine / cl_gui_chart_engine_win anzeigen, ändern, laden und speichern (XML), Beispiel-Charts

Einleitung

Mit Hilfe der Klasse cl_gui_chart_engine können Charts generiert werden. Über XML-Dokumente kann die Anzeige konfiguriert bzw. Daten angezeigt werden. SAP liefert zur einfachen Konfiguration ein Tool namens Chart Designer. Die XML-Daten können aber auch manuell generiert werden, eine genaue Beschreibung findet man im Dokument „XML Format.pdf“ des Chart Designers.
Mit Hilfe des unten stehenden Demo-Programms können auch XML-Daten für das Customizing generiert, geladen und gespeichert sowie Plot-Daten im XML-Format eingeladen werden. Es sind auch zwei einfache Beispiele für einen Bar-Chart sowie einen Scatter-Plot implementiert.
