I have a list of categories for all the business and personal activities I need to stay focussed on. I'm trying to create an interactive heat map, so that when I click on one activity the box it's in will change color. If I click on that same box again it will again change color, growing warmer. After five days of not clicking on an item I want each box to cool one color, and to do this for every five days that pass until it reaches the cool limit of the heatmap.
By doing this I can look at a table of to-do categories and see if I'm spending too much time on some, and not enough on others.
If this sort of thing is possible, please enlighten me!
Much Thanks,
Frank
