Just a kind followup if someone can show me how this is done.
Once I learn the priciple, I can use this for many other tasks I need to do.
many thanks in advance.
First of all, this is quite a bit troublesome to accomplish only by Tableau, but i tried to do at certain point.
Second, If you have only limited category of "% increase / decrease" counting that event is "do-able" but it's way more complicated.
Now I only add each event as text without counting the number of event, but in order of the event.
Step-1 % change
Step 2: Text
Step 3 Merge Text
