Heat Map of Frequency-Number Transitions in the Mega Lottery

Published:

Last Edited: June 9, 2009, 9:45 pm

Added one more tool, the "heat map" - here using a 2 dimensional rendering of the mega lottery frequency-number transition using last 100 draws

heat maps are useful when three data points are involved, in our example:

X - Frequency

Y - Frequency

Z - Number Occurence

Heat Maps assume X = Y, and intensity of color in our example indicates number of hits (Count)

Latest Draw     06/05/2009 5 20 38 41 52 +20 $0.00

Frequency       Count

03                     01
04                     04
05                     03
06                     03
07                     06
08                     08
09                     08
10                     06
11                     05
12                     07
13                     01
14                     02
15                     02

Note: below the white space indicate lowest frequency: 3 and 13 (highest frequency bright green 8 and 9), from my end I am constantly refining how the data is presented.  see below references.

above image was produced by the superfractal.cpp using gnuplot (ref. 1) and gnuplot C++ interface (ref. 2)
