Set Theme in AFL without changing my preferences

Hi
Is there a way to call a theme in AFL? eg: How do I set the theme to “Black Theme” for a particular chart in AFL without changing my preferences? I know how to use SetChartBkColor & SetChartBkGradientFill. Is there a way to call a standard theme.
Many thanks

No, you can not “call” a theme from AFL. You can only change colors using SetChartBkColor() and similar functions.
