Click on any free place in the Graphics View to create a slider for a number or an angle. The appearing dialog window allows you to specify the Name, Interval [min, max], and Increment of the number or angle, as well as the Alignment and Width of the slider (in pixels), and its Speed and Animation modality.

Note: In the Slider dialog window you can enter a degree symbol ° or pi (π) for the interval and increment by using the following keyboard shortcuts:
  • Alt-O (Mac OS: Ctrl-O) for the degree symbol °
  • Alt-P (Mac OS: Ctrl-P) for the pi symbol π

The position of a slider may be absolute in the Graphics View (this means that the slider is not affected by zooming, but always remains in the visible part of the Graphics View) or relative to the coordinate system (see Properties Dialog of the corresponding number or angle).

  • In GeoGebra, a slider is the graphical representation of a free number or free angle. You can easily create a slider for any existing free number or angle by showing this object in the Graphics View (see Context Menu; see tool Tool Show Hide Object.gif Show/Hide Object).
  • Sliders made with the Tool Slider.gif Slider Tool are fixed by default (from GeoGebra 4.0). To translate a fixed slider when Tool Move.gif Move Tool is selected, you can drag it with your right mouse button. When Tool Slider.gif Slider Tool is selected, you can use either left or right button.
