Is there any way that can let me move the whole graph by a "hand"?

I want to get the effect that the customers can move the whole graph by pressing the mouse right down,or use a “hand” instead of mouse.Like the operation drug the page in the pdfReader when you select the “hand”.
Following is my attachment:
like the second icon.

If you disable the DragSelectingTool, the PanningTool will be able to start.

Thx for your help,It worked!
