Thank you Stan for implementing the filtering of Number Difference Sum ranges in levels from Winning Numbers history charts. And thank you Viking for presentation of this filter's idea.
Stan, this might be one of the best filters in EL5 if you could improve it a bit.
To see clearly the patterns in the chart, I use the latest 52 drawings. Unfortunately, this history period shows the highest sum value during the last year only and it does not show the highest sum value in total game history. Moreover, there is no space in the chart to adjust the range of sums filtered above the highest sum which occurred in the last 52 drawings. It can have negative consequences. For example, the highest sum in a level in the last 52 drawing was 95 and the next drawing's sum is 97, but there was no space in the chart to make it 97. This is a kind of incorrect prefiltering.
When I open the chart using all drawings in the history the max sums are clearly visible, but the chart is so congested that the low and medium sums are very difficult to see.
It would be good if you could increase the space in the upper part of the charts which are based on a small number of latest draws (10 to 100 latest draws), to accomodate the highest sum that occured in the past and still are possible in the future in any level in the game. The range of available sums in the chart should be from 0 to at least the highest sum in the game history. If it was from 0 to the highest sum present in the package for a given level, it would be even better.
If you could also display the highest sum value in the game history in the chart, if this sum occurred before the analyzed period, it would be a further improvement.
