What is Measure filter?
A measure used in the visual filter is evaluated at a certain granularity defined by the visual. For a matrix visual, the filter granularity is defined by attributes applied to the Rows section of the matrix, ignoring the attributes applied to the Columns section.
How do you filter measures in looker?
To apply a filter directly to a measure, instead of filtering the entire query, we can add a filters parameter to the LookML definition of a measure. This will apply the filter, in the form of a CASE WHEN statement, to the measure in the generated SQL, as opposed to applying a global WHERE clause to the entire query.
How do you calculate filters?
For example:
- Circulation Rate: 100 cubic metres per hour.
- Filter Surface Area: 5.71 metres squared.
- Filtration Rate: 125m3 / 5.71m2 = 21.89m3/m2/hr.
- Width of filter: 2.7 metres (this is also the diameter)
- Radius: 2.7m / 2 = 1.35m.
- Radius Squared: 1.35m x 1.35m = 1.82 m2.
- Surface Area: 1.82m x 3.14 (pi) = 5.72 m 2.
What does DAX filter do?
The FILTER function in DAX allows you to iterate down the rows of any table, creating a row context for each and testing whether the row should be included in your calculation. You can combine filters using keywords like AND and OR and also nest one filter within another.

What is difference between filter and search?
Searching begins from nothing and adds to a list of results based on criteria that matches. Filtering begins from the full list of results and eliminates from that list based on which results do not match certain criteria. For example, let’s say you wanted to find the Post “Richard Wilbur on what poetry is”.
What is filter rate?
Filtration rate is the measure of how much water passes through a certain sized filter over a specific time. Typically filtration rates are expressed in gallons per minute per square foot of filter area (gpm/ft2). It is the flow of water through the surface area of a filter.
What are the factors affecting filtration?
Here is a list of all Factors Affecting Filtration Rates and Cake Moistures in plants or laboratory de-watering systems and processes.
- Particle Size of Solids.
- Ratio of slimes to coarser particles.
- Filter aids.
- Feed solids concentration.
- Filter Thickening.
- Slurry pH.
- Flocculation/Dispersion of fine solids.
- Slurry Age.
How do I filter with DAX measure?

- Syntax. DAX Copy.
- Return value. A table containing only the filtered rows.
- Remarks. You can use FILTER to reduce the number of rows in the table that you are working with, and use only specific data in calculations.

How do you add multiple filters on DAX?
Using Multiple filters in DAX
- Can you edit your question to format your example data into a table. This way we can get a better idea of how your data looks.
