Is it possible to select/highlight a region in the chart

I am trying to select a specific region in charts displayed. I need a way to highlight a region in the chart, say from coordinates (x1,y) to (x2,y) so that i can get a more detailed chart in another panel.
Though setCanZoom(true) method can display the zoomed part in another chart but I want the selected region to be highlighted as well.
Something similar to the image attached with this post is needed.

Thanks.
