Original Blog Entry: Heat Map of Frequency-Number Transitions in the Mega Lottery

edge — Wed, 10 Jun 2009 01:32:18 GMT

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)

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)
