Graphics View User Interface
The Graphics View is part of almost all Perspectives and always displays the graphical representation of objects created in GeoGebra. In addition, the Graphics View Toolbar is displayed at the top of the GeoGebra window, with the Undo / Redo buttons in the top right corner.
Customizing the Graphics View
The Graphics View may include various types of grids and axes. For more information see Customizing the Graphics View. You may also change the layout of GeoGebra’s user interface according to your needs.
Displaying a Second Graphics View
A second Graphics View may be opened using the View Menu. If two Graphics Views are opened, one of them is always active (either it's being worked with and it has bold caption, or it is the last View that has been worked with). All visible objects created by Commands appear in the active Graphics View. For each object you can specify in which Graphic View(s) it will be visible using the Advanced tab of the Properties Dialog.
Creating Mathematical Objects
Constructions with the Mouse
Using the construction Tools available in the Graphics View Toolbar you can create geometric constructions in the Graphics View with the mouse. Select any construction tool from the Graphics View Toolbar and read the tooltip provided in the Graphics View in order to find out how to use the selected Tool.
Graphics View Toolbar
The Graphics View Toolbar provides a wide range of Tools that can be operated with the mouse and allow you to create the graphical representations of objects directly in the Graphics View. Every icon in the Toolbar represents a Toolbox that contains a selection of similar construction Tools. In order to open a Toolbox, you need to click on the corresponding default Tool shown in the Graphics View Toolbar (GeoGebra Web and Tablet Apps) or on the small arrow in the lower right corner of the Toolbar icon (GeoGebra Desktop).
) and Tools that allow you to apply geometric transformations in the Transformations Toolbox (default icon 
).Direct Input using the Input Bar
You can also create objects in the Graphics View by entering their algebraic representation or corresponding Commands into the Input Bar.
Hint: The Input Bar can be shown using the View Menu.
Modifying Mathematical Objects
The Move Tool
After activating the Move Tool you are able to move objects in the Graphics View by dragging them with the mouse.
Copy & Paste
Via Keybord Shortcut Ctrl + C and Ctrl + V (Mac OS:Ctrl + C and Ctrl + V) you can Copy and Paste selected objects (except if they depend on the coordinate axes) into either the same or into another window.
The pasted object is fixed when you click on the Graphics View. If the copied object depends on at least one point then it can snap onto existing points when pasted (but only the point following the mouse pointer will do this).
Display of Mathematical Objects
Graphics View Style Bar
The Graphics View Style Bar contains buttons to
Show / Hide the Axes: You may show or hide the coordinate axes.
Show / Hide the Grid: You may show or hide the grid (GeoGebra Desktop) or select which type of grid should be shown (GeoGebra Web and Tablet Apps).
Go Back to Default View: If the view on the Graphics View was changed before, this button sets the origin of the coordinate axes back to its default position.
Change the Point Capturing Settings: You can choose between the settings Automatic, Snap to Grid, Fixed to Grid, and Off. For more information please see Point Capturing.
Style Bar for Tools and Objects
Depending on the Tool or object you select, the buttons in the Style Bar adapt to your selection. Please see Style Bar Options for Tools and Objects for more information.
Hiding Mathematical Objects in the Graphics View
You may hide objects in the Graphics View by either
- using the Show / Hide Object Tool
- opening the Context Menu and unchecking Show Object
