9.3.42: `
|
`show ...' |
Show some information by printing it to standard output.
show all
'
Show lots of information about plot.
show axes
'
Show information about axes.
show color
'
Show the current pen color used for lines and text. This is not to be
confused with image color, which is independent.
show colornames
'
Show all colors known by name, as defined by `read colornames
'
command and also the builtin colors defined automatically
(e.g. `white
', `black
', `red
', etc),
(see Read Colornames).
show columns
'
Show x, y, z, u, v column data.
show columns statistics
'
Show means, std devs, etc for columns.
show flags
'
Show values of all flags. (Developers only.)
show grid
'
Show an indication of the grid data (used for contouring).
show grid mask
'
Show 1 if grid data are valid or 0 if contours will not extend into this
region.
show image
'
Show information about image, such as a histogram of values, and, if the
image is small enough, the actual data.
show license
'
Show the license for Gri, which outlines how users are allowed to share
it freely.
show misc
'
Show miscellaneous information about the plot, the data, etc.
show next line
'
Show next line of data-file.
show synonyms
'
Show values of all synonyms, whether built-in or user-defined.
show stopwatch
'
Show elapsed time since first call to this command in the given Gri program.
show time
'
Show the current time.
show traceback
'
Show traceback (i.e., the tree of commands being done at this instant).
show variables
'
Show values of all variables, whether built-in or user-defined.
show .value.
'
Show value of indicated variable.
show {rpn ...}
'
Show result of computing indicated expression.
show "some text"
'
Print the indicated string. You may use a double-slash to prevent Gri
from substituting synonym values; thus it is common to do e.g.
\var = "Temperature" show "Plotting \\var = 'var'" |
which will produce the output line
Plotting \\var = 'Temperature' |
show "time=" .time. "; depth=" .depth.
'
Print strings and values as indicated. If the last item is ellipses
(three dots with no spaces between them), then no newline is printed;
this makes the next `show
' statement print on the same line.
To get a newline in a printed string, use the three-character glyph
`\<<
', and to get a horizontal tab, use `\>>
', as in the
examples below
\a = "HI" show "\\a=\a" system echo -e "a\\nb" show "first line\<<second line" show "first line\<<\>>(tabbed) second line" show "first line\<<\>>(tabbed) second line" |
