spheregrid
Plots a spherical grid around the origin of a 3-d plot. The radius of the sphere can be configured explicitly, otherwise a suitable default value (that should make at least some of the grid visible) will be chosen.
Usage Overview:
layerN=spheregrid radiusN=<number> gridcolorN=<rrggbb>|red|blue|... thickN=<pixels> nlonN=<int-value> nlatN=<int-value>
All the parameters listed here
affect only the relevant layer,
identified by the suffix
N
.
Example:
stilts plot2sphere legend=false xpix=350 ypix=350 layer1=mark in1=tgas_source.fits lon1=ra lat1=dec r1=1 shading1=transparent opaque1=850 color1=orange layer2=spheregrid gridcolor2=green thick2=2
gridcolorN = <rrggbb>|red|blue|...
(Color)
The standard plotting colour names are
red
, blue
, green
, grey
, magenta
, cyan
, orange
, pink
, yellow
, black
, light_grey
, white
.
However, many other common colour names (too many to list here)
are also understood.
The list currently contains those colour names understood
by most web browsers,
from AliceBlue
to YellowGreen
,
listed e.g. in the
Extended color keywords section of
the CSS3 standard.
Alternatively, a six-digit hexadecimal number RRGGBB
may be supplied,
optionally prefixed by "#
" or "0x
",
giving red, green and blue intensities,
e.g. "ff00ff
", "#ff00ff
"
or "0xff00ff
" for magenta.
