Colors in RST

RST includes a set of color tables which are used by the plotting routines. You can view the available color tables in the directory $COLOR_TABLE_PATH ($RSTPATH/tables/base/key).

Colors in RST are specified in the (hex) format ''AARRGGBB'':

  • AA refers to transparency (00 = fully transparent and FF = opaque)
  • RR,GG,BB refer to the 8-bit values for the red, green, and blue channels respectively

Making your own color palette

New color keys can be provided as a text file, for example:

# NEW VELOCITY COLOR KEY
#   blue=motion towards radar
#   red=motion away from radar
#   high contrast either side of 0 m/s
#
10
FFFF0000
FFFF3001
FFFF6002
FFFF9003
FFFFC105
FF1DED24
FF15B15A
FF0E7691
FF073BC8
FF0000FF

The first non-comment line specifies the number of colors in the key. Ideally this should be a multiple of 10 so that the colors align with the tick marks when displayed on plots (the number of tick marks is fixed).

To use your new color key:

field_plot [options] -key [newcolorkey.key] [file.fitacf]
time_plot [options] -vkey [newcolorkey.key] [file.fitacf]

In time_plot, you can replace -vkey with -pkey, -wkey, -fkey or -nkey to specify color keys for the power, spectral width, frequency and noise respectively.

If you want to keep your new color key in a directory other than $COLOR_TABLE_PATH, you can specify the path using -vkey_path, -xkey_path etc. Type [function name] --help | grep key_path to view the available options.
