gCalcD: Translating the Coordinate System

You can translate the coordinate system either by entering data, by pressing the arrow keys on keyboard or by using your mouse.

• Enter the coordinates of the points you want to translate the origin to and press the Translate button. Press the Reverse button to move in the opposite direction.
• Or
  Press the arrow keys ← ↑ ↓ → on the keyboard to move along the axes in the corresponding direction.
• Or using your mouse:
  You can translate the coordinate system by dragging it with your mouse, that is, hold down the mouse button and move the mouse. The coordinate system will move accordingly and the graph(s) will be re-drawing over the newly calculated domain. This enables you to translate the coordinate system to any point that is not even on the drawing area. By doing this repeatedly, you can move to and view any region of the coordinate system.
  
  

To translate the origin of the coordinate system to a point on the drawing area just double click on that point. The origin will move to where you have double clicked and the graph(s) will be re-drawn.
