Line 7:
::As WP says: "It is important that each stem is listed only once and that no numbers are skipped, even if it means that some stems have no leaves." This ensures that the vertical direction is always a linear scale. This is not just a table: it is an information graphic. Distances matter. —[[User:Kevin Reid|Kevin Reid]] 14:42, 14 December 2009 (UTC)
==Less Useful for negative numbers?==
For data: 15 14 3 2 1 0 -1 -2 -3 -14 -15
Would you generate either graph1:
-2 | 5 6
-1 | 7 8 9
0 | 0 1 2 3
10 | 4 5
Which satisfies X | Y where 10*X + Y is a datum, but the digit for Y when the datum<0 is not necessarily the right-most digit of the datum.
Or graph 2:
-1 | -4 -5
0 | -3 -2 -1 0 1 2 3
10 | 4 5
Which also satisfies X | Y where 10*X + Y is a datum, the last digit is preserved, but I don't like the negative leaf numbers. <br>
What thinketh though? --[[User:Paddy3118|Paddy3118]] 13:38, 16 December 2009 (UTC)
