ZoomIn( )
Restores the Menu view graphics.svg Graphics View to the default initial position
ZoomIn( <Scale Factor> )
Zooms the Menu view graphics.svg Graphics View in by given factor with respect to current zoom, center of the screen is used as center point for the zoom.
Example:
ZoomIn(1) doesn't change the view, but does remove traces
ZoomIn(2) zooms the view in
ZoomIn(0.5) is equivalent to ZoomOut(2), i.e. it zooms the view out.


ZoomIn( <Scale Factor>, <Center Point> )
Zooms the Menu view graphics.svg Graphics View in by given factor with respect to current zoom, second parameter specifies center point for the zoom.
Example:
ZoomIn(2, (0, 0))


ZoomIn( <Min x>, <Min y>, <Max x>, <Max y> )
Zooms the graphics view to the rectangle given by vertices (Min x, Min y), (Max x, Max y).
Example:
ZoomIn(0, 1, 5, 6)
Note: If any of these parameters are dependent or has label set, the bounds of the view become dynamic. To avoid this behavior, use CopyFreeObject Command.
Example:
If a is a slider, ZoomIn(-a, -a, a, a) makes the zoom of the view dependent on slider a.


ZoomIn( <Min x>, <Min y>, <Min z>, <Max x>, <Max y>, <Max z> )
Zooms the 3D graphics view to the cuboid given by vertices (Min x, Min y, Min z), (Max x, Max y, Max z).
Example:
ZoomIn(-5, -5, -5, 5, 5, 5)
Note: The dynamic behavior of the 2D version isn't supported

Idea of Use[edit]

Linear aproximation of a function by its tangent[edit]

Create a function f with a point A on it and a button with the code ZoomIn(2,A) to see that the function looks equal to the tangent for a big "magnification". Another button with ZoomOut let you be able to prove this at other positions of the point A.
