Description
A strategy class used by the default setup of cHistogram. It is meant to provide a good quality uniform-bin histogram without requiring manual configuration.
This strategy uses precollection to gather input information about the distribution before setting up the bins. Precollection is used to determine the initial histogram range and the histogram mode (integers vs. reals). In integers mode, bin edges will be whole numbers.
To keep up with distributions that change over time, this histogram strategy can auto-extend the histogram range by adding new bins as needed. It also performs bin merging when necessary, to keep the number of bins reasonably low.
Collected infinities are counted as underflows/overflows, and they do not affect the histogram layout in any way.
Member Function Documentation
◆ dup()
|
inlineoverridevirtual |
Should be redefined in subclasses to create an exact copy of this object. The default implementation just throws an error, to indicate that the method was not redefined.
Reimplemented from cObject.
◆ collect()
|
overridevirtual |
Called from cHistogram's collect() method. Implementations are expected to call back cHistogram's collectIntoHistogram(), or if histogram bins are not yet set up, store it for later.
Implements cIHistogramStrategy.
◆ collectWeighted()
|
overridevirtual |
Called from cHistogram's collectWeighted() method. Implementations are expected to call back cHistogram's collectIntoHistogram(), or if histogram bins are not yet set up, store it for later.
Implements cIHistogramStrategy.
◆ clear()
|
inlineoverridevirtual |
Called from cHistogram's clear() method, to give the strategy object an opportunity to clear its state.
Reimplemented from cPrecollectionBasedHistogramStrategy.
