delete_histogram

Context: histograms

Synopsis

Delete the specified histogram.

Syntax

delete_histogram()
delete_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 deleted, otherwise the argument determines what to delete.


Examples

Example 1

chips> add_histogram([1,2,3], [10, 15, 20],["dropline", "off"])
chips> delete_histogram()

Create a histogram, then delete it.

Example 2

chips> id = ChipsId()
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> id.histogram = "basic"
chips> delete_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 deleted.

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> delete_histogram("all")

Two histograms are created, then the delete_histogram command deletes them both.
