These calculations let you apply different aggregates at different levels in your data. For example, you can sum revenue up to the month level, and then take an average of that total to display at the year level.
The result would look something like this:
The calculations included in the Aggregate category are:
Average within category
Variance within category
Max within category
Min within category
Filters and baselines
This category of calculations lets you calculate values for a specific category in a column, or compare values to a specific baseline. For example, the following quick measure calculates the SalesAmount for just Deluxe Class products:
A card is a good way to display these filtered measures:
The calculations included in this category of quick measures are:
Filtered measure
Difference from baseline
Percentage difference from baseline
Time intelligence
If you need a measure that shows period-to-date or period-over-period values, the time intelligence category of calculations lets you do this.
For example, you can calculate the sales amount over the order year to date.
Here’s the result of that calculation alongside the unaggregated value:
The included calculations are:
Year-to-date total
Quarter-to-date total
Month-to-date total
Year over year change
Quarter over quarter change
Month-over-month change
At present, the time intelligence calculations only work with date fields with Power BI’s built-in date hierarchies. If you’re using your date field in visuals and see Date Hierarchy on the field well menu, then you can use that field in the time intelligence quick measures.
We’re looking to remove that date hierarchy restriction in the future, so you can easily use your own date tables too.
Running total
This category (it’s just one calculation, so far) is similar to the YTD calculation, but lets you apply a running total over any field, not just dates.
Here’s an example adding up the sales amount over each product class:
Mathematical operations
These calculations run simple mathematical functions, which can become powerful when chained together.
Here’s an example showing a few chained together to produce line item total values.
The included calculations are:
Addition
Subtraction
Multiplication
Division
Percent difference
You can create a quick measure by selecting Quick measures from the field menu, either in the field well of a chart or from the field list.
In the dialog, you can choose which of the 19 different calculations you want to perform on your selected measure. Depending on the calculation, you’ll see different parameters you’ll be required to fill in. You can also change which fields are being used in the calculation by using the field list on the right half of the dialog.
After you provide the required parameters and click OK, the quick measure is now part of your model and available to use in your other visuals. If you had originally launched the quick measures dialog from the field well of a visual, the new measure is added to the visual.
In addition, just like any other measure, you can see the DAX formula that Power BI used to create this new measure. This is a great way to learn more about DAX.
