Customizing the User Interface

The user interface of GeoGebra can be customized by using the View menu. For example, you can hide different parts of the interface (e. g., the Algebra View, Spreadsheet View, or Input Bar) by checking or un-checking the corresponding menu item in the View menu.

Showing and Hiding Objects

You may show or hide objects in the Graphics View in different ways.

·        You may use tool mode_showhideobject_32 Show/Hide Object to show or hide objects.

·        Open the Context Menu and select item mode_show_hide_button_32 Show Object to change the visibility status of the selected object.

·        In the Algebra View, the icon to the left of every object shows its current visibility state (shown shown or hidden hidden). You may directly click on the little marble icon in order to change the visibility status of an object.

·        You can also use the tool mode_showhide_checkbox_32 Check Box to Show/Hide Objects in order to show or hide one or several objects.

Customizing the Graphics View

In order to adjust the visible part of the drawing pad in the Graphics View, you can drag the drawing pad by using tool mode_translateview_32.gif Move Drawing Pad and use the following ways of zooming:

·        You may use the tools mode_zoomin_16 Zoom In and mode_zoomout_16 Zoom Out in order to zoom in the Graphics View.
Note: The position of your click determines the center of zoom.

·        You may use the scroll wheel of your mouse in order to zoom in the Graphics View.

·        You may use keyboard shortcuts to zoom in (Ctrl +) and to zoom out (Ctrl -).

·        After right clicking (Mac OS: Ctrl-click) on an empty spot on the drawing pad a Context Menu appears which allows you to Zoom.

·        You may specify a zoom rectangle by right clicking (Mac OS: Cmd - click) on an empty spot in the Graphics View and dragging the mouse to the opposite corner of your desired zoom rectangle. Release the mouse button in order to finish the zoom rectangle, which will then automatically adjust to fill all the space in the Graphics View.

 

You can also show or hide the coordinate axes and a coordinate grid in the Graphics View by using the View menu.

Note: Another way of showing or hiding the axes and the grid is by right clicking (Mac OS: Ctrl-click) on the drawing pad and selecting the corresponding items axes.gif Axes or grid.gif Grid from the appearing Context Menu.

Customizing Coordinate Axes and Grid

The coordinate axes and grid can be customized using the Properties Dialog of the Graphics View. After right clicking (Mac OS: Ctrl-click) on the drawing pad, you can open this dialog window by selecting Properties from the appearing Context Menu of the Graphics View.

·        On tab Axes, you can, for example, change the line style and units of the coordinate axes, and set the distance of the tickmarks to a certain value. Note that you can customize both axes individually, by clicking on tabs xAxis or yAxis. Furthermore, you can also change the ratio between the axes and hide or show the axes individually.

·        On tab Grid, you can, for example, change the color and line style of the coordinate grid, and set the distance for grid lines to a certain value. In addition, you may also set the grid to be Isometric.

 

Note: Scaling the axes is possible in every mode by pressing and holding the Shift-key (PC: also Ctrl-key) while dragging the axis.

 

Note: The Properties Dialog of the Graphics View is different from the Properties Dialog for objects.

Customizing the Toolbar

The Toolbar can be customized by selecting Customize Toolbar… from the Tools menu. Select the tool or toolbox you want to remove from the Toolbar in the list on the left hand side of the appearing dialog window and click button Remove > in order to remove the tool/toolbox from the Toolbar.

 

Note: You can restore the default Toolbar by clicking on the button Restore Default Toolbar in the left lower corner of the dialog window.
