Occasionally, you will find the need to compare filtered data against the total data source. As Tableau's filters remove the data from the data partition, this can sometimes be a tricky problem. You might be tempted to try the "Total" function in a formula like the...

So, Here's the "Why" In Tableau, we are easily able to slice and dice the data according to our dimensions thanks to the default manner in which Tableau aggregates the data on our behalf. Therefore, I can simply add any measure and trust the view is...
