No headers There are several controls that can be useful for manipulating the plot window. These change your view of the data without affecting the data themselves, and without changing how processing is performed (except the processing required to render the plot window, of course).
The controls are modelled on those of Google maps. For those controls which are keystrokes, the plot window must have focus (i.e. be the "current" window, usually shown by a highlighted title bar).
If your mouse does not have a wheel, it can be simulated using Alt-Up or Alt-Down (the plot window must have focus).
Name
| Control | Effect on plot window
|
set default view
| "=" (Equals key)
| rotate so North is up; pan so the radar is at the centre of the plot window, and set the scale to 5 metres per pixel. The default rotation and scale can be set by changing the items default.north.angle and default.mpp in the file:
radR/gui/gui.conf.R
|
pan
| drag with left button, then release
| changes the geographic location of the centre of the plot window
|
zoom in
| mousewheel up
or
Alt-Up
or
"-" (minus key)
| decreases the metres per pixel; zoom is centred on the centre of the plot window
|
zoom out
| mousewheel down
or
Alt-Down
or
"-" (minus key) | increases the metres per pixel; zoom is centred on the centre of the plot window |
rotate clockwise
(coarse)
| Ctrl-mousewheel down (i.e. Ctrl key held down while mouse wheel rolled down)
or
Ctrl-Alt-Down
| rotates the display clockwise by 10 pulses (configuration file item: gui/gui.conf.R:plot.big.rotation.increment)
|
rotate counterclockwise
(coarse) | Ctrl-mousewheel up
or
Ctrl-Alt-Up | rotates the display counterclockwise by 10 pulses |
rotate clockwise
(fine) | Ctrl-Shift-mousewheel down
or
Ctrl-Shift-Alt-Down | rotates the display clockwise by 1 pulse |
rotate counter clockwise
(fine) | Ctrl-Shift-mousewheel up
or
Ctrl-Shift-Alt-up | rotates the display counterclockwise by 1 pulse |
forward scan
| Shift-mousewheel up
| moves to the next scan in the data source and displays it; this is in "preview" not "play/process" mode, and is equivalent to moving the player slider one notch right
|
| backward scan | Shift-mousewheel down
| moves to the previous scan in the data source and displays it; this is in
"preview" not "play/process" mode, and is equivalent to moving the
player slider one notch left |
change compass radius
| Ctrl-left button drag
or
Ctrl-left button click
| sets the compass radius so that the compass passes through the current mouse location. This can be set numerically in the display options window
|
change range-ring spacing
| Shift-left button drag
or
Shift-left button click
| changes the range ring spacing so that the ring closest to the current mouse location is brought directly to the mouse location.
