Hi endator,
What do you exactly mean, which charts are not clear?
For example - DT Matrix or Finds by found date or Finds by hidden date are classic heat maps. Black font in Finds by found date is explained. :)
Other charts like Finds by year cache placed are just pie charts with random colors to discriminate sets of data.
In charts like Finds by month per year brown color means that you have at least one find/attend on every single day in a month.
For me - the only thing I don't understand is bold in Way to 81 in D/T column.
I hope it helps... and that I'm not wrong :)
Cheers,
