HistogramBasic() method from fcf::NTest::HistogramBasic class

[CONSTRUCTOR] HistogramBasic()

[CONSTRUCTOR] HistogramBasic(size_t a_capacity)

[CONSTRUCTOR] HistogramBasic(size_t a_capacity, TItem a_min, TItem a_max)

Class: fcf::NTest::HistogramBasic

Package: fcfTest

File: test.hpp

Available from version: 1.2.5

Constructs a new histogram with specified capacity and range.

The HistogramBasic constructors allow for different initialization strategies:

Default Constructor: Creates an empty histogram with a default capacity of 10 bins.
Capacity Constructor: Creates a histogram with a specified initial number of bins.
Range Constructor: Creates a histogram with a fixed range defined by a_min and a_max, and a specified capacity.

Arguments

size_t a_capacity

- The initial number of bins in the histogram.

TItem a_min

- The minimum boundary of the histogram range.

TItem a_max

- The maximum boundary of the histogram range.

Example: Initializing different types of Histograms

Demonstrating how to create histograms with default settings, specific capacity, and fixed ranges.

#define FCF_TEST_IMPLEMENTATION #include <fcfTest/test.hpp> #include <iostream> FCF_TEST_DEFINE("HistogramDemo", "Basic", "ConstructorTest") { // 1. Default constructor (10 bins, auto-range) fcf::NTest::HistogramBasic<double> hist1 = fcf::NTest::HistogramBasic<double>(); // 2. Constructor with capacity (50 bins, auto-range) fcf::NTest::HistogramBasic<double> hist2(50); // Append some data to verify hist2.append(10.5); hist2.append(50.0); hist2.append(99.9); fcf::NTest::log() << "Hist2 size: " << hist2.size() << std::endl; fcf::NTest::log() << "Hist2 min: " << hist2.min() << std::endl; fcf::NTest::log() << "Hist2 max: " << hist2.max() << std::endl; // 3. Constructor with capacity and fixed range [0.0, 100.0] fcf::NTest::HistogramBasic<double> hist3(50, 0.0, 100.0); // Append some data to verify hist3.append(10.5); hist3.append(50.0); hist3.append(99.9); fcf::NTest::log() << "Hist3 size: " << hist3.size() << std::endl; fcf::NTest::log() << "Hist3 min: " << hist3.min() << std::endl; fcf::NTest::log() << "Hist3 max: " << hist3.max() << std::endl; FCF_TEST(true); } int main(int a_argc, char* a_argv[]) { bool error = false; fcf::NTest::cmdRun(a_argc, a_argv, fcf::NTest::CRM_RUN, &error); return error ? 1 : 0; }
