70.15 Decimalsign
The set decimalsign command selects a decimal sign for numbers printed into tic labels or set label
strings.
Syntax:
set decimalsign { | locale {""}}
unset decimalsign
show decimalsign
The argument is a string to be used in place of the usual decimal point. Typical choices include
the period, ’.’, and the comma, ’,’, but others may be useful, too. If you omit the argument,
the decimal separator is not modified from the usual default, which is a period. Unsetting decimalsign
has the same effect as omitting .
Example:
Correct typesetting in most European countries requires:
set decimalsign ’,’
Please note: If you set an explicit string, this affects only numbers that are printed using gnuplot’s
gprintf() formatting routine, include axis tics. It does not affect the format expected for input data, and
it does not affect numbers printed with the sprintf() formatting routine. To change the behavior of both
input and output formatting, instead use the form
set decimalsign locale
This instructs the program to use both input and output formats in accordance with the current setting
of the LC ALL, LC NUMERIC, or LANG environmental variables.
set decimalsign locale "foo"
This instructs the program to format all input and output in accordance with locale "foo", which must
be installed. If locale "foo" is not found then an error message is printed and the decimal sign setting
is unchanged. On linux systems you can get a list of the locales installed on your machine by typing
"locale -a". A typical linux locale string is of the form "sl SI.UTF-8". A typical Windows locale string
is of the form "Slovenian Slovenia.1250" or "slovenian". Please note that interpretation of the locale
settings is done by the C library at runtime. Older C libraries may offer only partial support for locale
settings such as the thousands grouping separator character.
set decimalsign locale; set decimalsign "."
This sets all input and output to use whatever decimal sign is correct for the current locale, but over-rides
this with an explicit ’.’ in numbers formatted using gnuplot’s internal gprintf() function.
70.16 Dgrid3d
The set dgrid3d command enables, and can set parameters for, non-grid to grid data mapping. See
splot grid data (p. 153) for more details about the grid data structure.
