Histogram

What is a histogram?

• A visual representation that charts the frequency distribution of the regularity of an occurrence of a value in a data set.
• Often confused with a bar chart, although there are certain defining characteristics or points of differentiation.
• The x-axis consists of equal width bars without space in between, known as bins or buckets that represent a range of classes.
• x axis is the class interval and is identified with a number rather than a description or label.
• The y axis represents the frequency of occurrence of a value.
• Bar graphs represents data that is discrete or categorical in nature

Uses

• In statistics to show the frequency of a specific value within a certain range.
• Used to analyse large amounts of data easily to detect trends and patterns.

Change-log:

• 06/04/2023 - Initial release
• 04/04/2023 - Foundation code

Compilation

type make or cc -o histo histogram.c -lm on the command line

Misc.

• I have included both uniform and gaussian (normal) distribution data files.
• Gnuplot or some equivelant application is required to graph the histogram data.
• I find gnuplot then plot 'dist3.dat' using 1:2 smooth freq w boxes works well (see png file for sample output).

Todo

• Need to use SDL2 to implement internal plotting routine.
• Logical bugs still exit, and so this is very much still a work in progress.
