Detailed Description

Equidistant histogram for doubles.

cDoubleHistogram is derived from cEqdHistogramBase which contains most of the functionality.

Examples:

The following histogram will determine the range from the first few observations, then it set up 10 equal-size cells on it:

 cDoubleHistogram hist("hist");

This one will create 30 cells, after determining the range from the first few observations:

 cDoubleHistogram hist("hist");
 hist.setNumCells(30);

To explicitly control the cells, you can use the following:

 cDoubleHistogram hist("hist");
 hist.setRange(0,3);
 hist.setNumCells(30);

If you only know that the numbers will be nonnegative, but you don't know their ranges, you can use the following (which will set up 20 cells, between 0 and an auto-determined limit):

 cDoubleHistogram hist("hist");
 hist.setRangeAutoUpper(0);
 hist.setNumCells(20);

Member Function Documentation

virtual cPolymorphic* cDoubleHistogram::dup  )  const [inline, virtual]
 

Creates and returns an exact copy of this object.

See cObject for more details.

Reimplemented from cStdDev.

cDoubleHistogram& cDoubleHistogram::operator= const cDoubleHistogram  )  [inline]
 

Assignment is not supported by this class: this method throws a cRuntimeError when called.

virtual double cDoubleHistogram::random  )  const [virtual]
 

Returns a random number based on the distribution collected.

If no values have been collected, it returns 0; when in initial collection phase, it returns one of the stored observations; after the histogram has been set up, a random integer is returned.

Reimplemented from cStdDev.

virtual void cDoubleHistogram::setupRange  )  [protected, virtual]
 

Called internally by transform(), this method should determine and set up the histogram range.

It also calculates the cell size.

Reimplemented from cEqdHistogramBase.
