Quadrants always exist with a plot. They can never be deleted, but they can be hidden.

 

There are several ways to hide quadrants:

 

•Right-click on the plot and deselect the Show Quadrants item on the pop-up menu.

 

•Right-click on the plot and select Format from the pop-up menu. Go to the Quads page of the format dialog and uncheck the Show quadrants box.

 

•Select the plot and use the Format tab→2D Options→Quadrants command. Uncheck the Show quadrants box.

 

•Select the quadrants by clicking on the central vertex. Press the Delete key on the keyboard, or select the Home tab→Editing→Delete command.
