scrolling
The mouse wheel adjusts x and y axis ranges in both 2D and 3D plots.
Each adjustment increment is 10% of the current range by default.
This may be changed by set mouse zoomfactor <x-multiplier>, <y-multiplier>.
- <wheel-up> scrolls y and y2 axis ranges up by a fraction of the current range
- <wheel-down> scrolls y and y2 ranges down by a fraction of the current range
- <shift+wheel-up> scrolls left (decreases x and x2 ranges)
- <shift+wheel-down> scrolls right (increases x and x2 ranges)
- <control+wheel-up> zooms in around the current mouse position
- <control+wheel-down> zooms out around the current mouse position
- <shift+control+wheel-up> zooms in only along x and x2 (pinch)
- <shift+control+wheel-down> zooms out only along x and x2 (expand)
