Having some trouble with this while I'm still learning the ins & outs of tableau...
I'm trying to show a heatmap of percentages of # of positive items in a list -- higher % positive green, lower % positive would be red -- with larger boxes for more entries.
Does that require a calculated field? It looks good as a % by row bar chart, but I think it would pop better as a heat map to incorporate size.
Thanks in advance, community.
You can use the ShowMe! box for the initial creation of the heat map. Then, use your measure on both the size and color shelf.
Hope this helps!
