4.3 Zooming Operations

Calling Sequences

Descriptions

zoom_factor sets the zoom factor for mouse-click zoom in and zoom out operations. The default factor is 1.5; factor should always be greater than 1.0.

unzoom restores limits to their values before zoom and pan operations performed interactively using the mouse. Use

old_limits = limits()

...

limits( old_limits )

to save and restore plot limits generally.
