By default, plots with color maps with single-parameter color mappings are accompanied by color scale bars, which appear by default on the right-hand side of the plot. Such scale bars may be configured using the set colorkey command. Issuing the command
set colorkey
by itself causes such a scale to be drawn on graphs in the default position, usually along the right-hand edge of the graphs. The converse action is achieved by:
set nocolorkey
The command
unset colorkey
causes Pyxplot to revert to its default behaviour, as specified in a configuration file, if present. A position for the key may optionally be specified after the set colorkey command, as in the example:
set colorkey bottom
Recognised positions are top, bottom, left and right. above is an alias for top; below is an alias for bottom and outside is an alias for right.
The format of the ticks along such scale bars may be set using the set c1format command command, which is similar in syntax to the set xformat command (see Section ), but which uses c as its dummy variable.
The positions of the ticks along color scale bars may be set using the set c1tics command command, which has similar syntax to the set xtics command.
