Hi Alex,
Greetings from Syncfusion support.
In Gantt, we don’t has label like Resource Name in control UI, please share screenshot in which place you need to change the label in Gantt.
Are you need to change the header text name of resource? Please refer the below screenshot and share the details about your requirement?
If you are asking about mapping resource properties to Gantt control with your fields in datasource, please refer below UG link.
Regards,
Pooja Priya K
