I am using slider with area chart, If we are sliding the the trend, its zooming into the view right !!!!

Instead of zooming, I just want to highlight the area of chart!!

How can i customize that ???

Start by reviewing the linked G2Plot area-chart slider example and the reported behavior in the v2.* context. Determine whether the slider can be customized to highlight the selected chart area instead of zooming; done means documenting or demonstrating that interaction clearly.
