Find a way to represent plant data over time

Noticed this page has an interesting characteristic:

HXW@10YRS: 8'x4'

This concept is easy to represent over time in more regular intervals e.g.

HXW@2YRS: 3'x1'
HXW@5YRS: 4'x2'
HXW@10YRS: 8'x4'
Etc

And if a plant doesn't typically live as long, it would have a null value:

HXW@10YRS: null

Which makes it easy to search where matches are in a time range AND height range.

This would be separate of something like average or max height, or could be used that way as well.
