display_histogram

Context: histograms

Synopsis

Display the specified histogram.

Syntax

display_histogram()
display_histogram(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 histogram is shown, otherwise the argument determines what to show.


Examples

Example 1

chips> add_histogram([5,8,13], [10, 15, 20], [12, 17, 22], "id=basic")
chips> hide_histogram("basic")
chips> display_histogram()

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

Example 2

chips> add_histogram([5,8,13], [10, 15, 20], [12, 17, 22], "id=basic")
chips> hide_histogram("basic")
chips> add_histogram([8,10,14], [12, 17, 22], [14, 19, 24], [1,1,2],
"id=witherrs")
chips> add_histogram([8,10,14], [12, 17, 22], [14, 19, 24], [1,1,2],
["id", "witherrs", "symbol.style", "diamond", "err.style", "capped"])
chips> id = ChipsId()
chips> id.histogram = "basic"
chips> display_histogram(id)

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

Example 3

chips> add_histogram([5,8,13], [10, 15, 20], [12, 17, 22], "id=basic")
chips> add_histogram([8,10,14], [12, 17, 22], [14, 19, 24], [1,1,2],
["id", "witherrs", "symbol.style", "diamond", "err.style", "capped"])
chips> hide_histogram("all")
chips> display_histogram("all")

Two histograms are created and hidden, then the display_histogram command displays them both.
