I am playing with tableau dashboard, I have below data.
.
so I have 2 users for Facebook, 2 users for Google and 1 user for Yahoo. I created a Bar chart to show the number of users per application, like below
its showing 4 users for Facebook, 4 for Google and 2 for Yahoo, basically it's just giving me a number of records. How do I filter duplicates and just show correct values?
