The toolbar is displayed vertically at the top left of the Grace window:


* The magnifying glass allows you to zoom by defining an area with the mouse;


* The "AS" icon (for autoscale) allows you to redefine the framing (zoom) automatically.


* The "Z" and "z" buttons are used to unzoom and zoom respectively.


* The arrows are used to move the drawn area.


* autoT: automatic definition of the graduations based on the curve closest to the point clicked.


* AutoO: automatic framing from the curve closest to the clicked point


* ZX, ZY: like the magnifying glass but in only one direction (X or Y)


* AX, AY: automatic framing in only one direction (X or Y)

The other buttons concern the management of the graph stack and will not be explained here.
