They show what we expect, and their only function is to check if the table calculation works properly. While the numbers are correct, and the percentages do indeed add up to 100 %, those Grand Totals offer only limited value. So basically, all percentages of one country add up to 100%:Ībove: The table calculation (Percent of Total, the computation using the Year of Year) calculates relative percentages for each country. We want to see the relative share for each year with a percentage. But in this case, we don’t want to see the absolute numbers. First, we created a view with a table that shows the CO2 Emissions for each Country from left to right and for each Year from top to bottom. Let’s go through this process step by step. So, let’s skip this and circle back to our SIZE solution.
not as independent because the COUNTD at the beginning depends on a specific dimension. a bit more complicated (especially when we’re not that familiar with Level of Detail calculations). This calculation provides more or less a similar logic as our solution below, but it is: Of course, we get where we want using a Level of Detail construct: And before we dive into our solution, let’s look at one other reason why we are doing this: we are not keen on working with LODs (at least not here). There, it gets a bit tricky, and we definitely need at least one calculated field to go around that. That’s it.īut what if we want more? What if we want to assign a different number type to our totals or have the Grand Total calculate something completely different than all the other marks in our bar chart? We can format them, choose among the four default aggregations of SUM, AVG, MIN and MAX, and-if we are really in for it-we can add Sub Totals and do the same stuff. Grand Totals are their own entity in Tableau. Change the created field’s Grand Total format to Number.ĭo that (or a little variation of that) and you will get one of these:Ībove: Manipulating grand totals! Woah … Wait! What Problem Did We Just Solve?. Change the created field’s default format to Percentage. Adjust the table calculation (compute over Year of Year). Create a calculated field and use the SIZE() function:ĮLSE SUM() / TOTAL(SUM()). Next, build the absolute metrics for Grand Total: Add a table calculation (percent of total, over Year of Year). 
Drag Year on Rows and Country on Columns to build a table.Quick Steps: What to Doįirst, we need to build the view with relative metrics: Below are the quick steps, followed by a detailed explanation that covers the “why” behind all of this. So, if you have had this problem or are currently dealing with it, let’s jump into the solution. Most times when it comes to Grand Totals, it is about tinkering with a table or plot so that it will show the most valuable output for the user.
#Grandtotal += checkvalue how to#
To my surprise, the question of how to manipulate Grand Totals in Tableau arises quite frequently.
