AHELP for CIAO 4.11 ChIPS v1

display_line

Context: lines

Synopsis

Display the specified line.

Syntax

display_line()
display_line(id)

Description

The function arguments.

Argument Description
id A ChipsId structure identifying the item, or a string containing the name of the object.

If no argument is given then the current line is shown, otherwise the argument determines what to show.


Examples

Example 1

chips> add_line(0, 0, 1, 1)
chips> hide_line()
chips> display_line()

Create a line and hide it, then display the current line.

Example 2

chips> add_line(.1, .3, .9, .3, "id=flat")
chips> hide_line("flat")
chips> add_line(.3, .8, .8, .2, "id=slope")
chips> id = ChipsId()
chips> id.line = "flat"
chips> display_line(id)

Two lines are created; the second line is current after it is created. The id.line command sets the line value of the ChipsId structure to the first line. That line is then displayed.

Example 3

chips> add_line(.1, .3, .9, .3, "id=flat")
chips> add_line(.3, .8, .8, .2, "id=slope")
chips> hide_line("all")
chips> display_line("all")

Two lines are created and hidden, then the display_line command displays them both.
