Rich Text Benutzerdefinierte Datenbeschriftung für Diagrammpunkt mit JavaScript via C++

Benutzerdefinierte Rich-Text-Datenbeschriftung des Diagrammpunkts

Der folgende Code greift auf den ersten Diagrammpunkt der ersten Serie zu, setzt seinen Text und legt dann die Schriftart der ersten 10 Zeichen fest, indem er die Farbe auf Rot setzt und die Fettdruck-Option auf true setzt.
