vaadin-charts set drilluptext

Is it possible to set a different drilluptext via the java api? e.g. to translate it?

Yes, should be possible. Include {series.name} in the translated string to include the parent series name

public void setDrillUpText(String drillUpText)
The text for the button that appears when drilling down, linking back to the parent series. The parent series’ name is inserted for {series.name}.
Defaults to: Back to {series.name}
