Add Measures to Power BI Desktop Model

  •  There are two types of measures one is Implicit and another is explicit
  • 1. Implicit Measures
  • Implicit measures are automatic behaviors that allow visuals to summarize model column data. The following sections focus on how you can use implicit measures.
  • In the Fields pane, a column that's shown with the sigma symbol ( ∑ ) indicates two facts:

  • It's a numeric column.

  • It will summarize column values when it is used in a visual (when added to a field well that supports summarization).

  • Implicit measures allow the report author to start with a default summarization technique and lets them modify it to suit their visual requirements.

    Numeric columns support the greatest range of aggregation functions:

    • Sum

    • Average

    • Minimum

    • Maximum

    • Count (Distinct)

    • Count

    • Standard deviation

    • Variance

    • Median

    Summarize non-numeric columns

Non-numeric columns can be summarized. However, the sigma symbol does not show next to non-numeric columns in the Fields pane because they don't summarize by default.

Text columns allow the following aggregations:

First (alphabetically)
Last (alphabetically)
Count (Distinct)
Count 
Date columns allow the following aggregations:
Earliest
Latest
Count (Distinct)
Count 
Boolean columns allow the following aggregations: 
Count (Distinct)
Count

 

2. Explicit Measure :

Explicit measures, also known simply as measures, are calculations that you can add to your model.

Conclusion 

Understood what is implicit and Explicit measures.

Use DAX iterator functions in Power BI Desktop models

Data Analysis Expressions (DAX) include a set of functions known as  iterator functions . Iterator functions enumerate all rows of a given table and evaluate a given expression for each row. They provide you with flexibility and control over how your model calculations will summarize data. Some DAX Functions are Complex summarization 1. SUMX e.g. : 1.  Revenue = SUMX (Sales, Sales[Sales Amount]) 2. Revenue = SUMX (Sales, Sales[Order Quantity] * Sales[Unit Price] * ( 1 - Sales[Unit Price Discount Pct.])) 3. Discount = SUMX ( Sales, Sales[Order Quantity] *( RELATED ('Product'[List Price]) - Sales[Unit Price] ) ) 2. AVERAGEX e.g :1. Revenue Avg = AVERAGEX ( Sales, Sales[Order Quantity] * Sales[Unit Price] * ( 1 - Sales[Unit Price Discount Pct.]) ) 2. Revenue Avg Order = AVERAGEX ( VALUES ('Sales Order'[Sales Order]), [Revenue] ) 3. RANKX The  RANKX  DAX function is a special iterator function you can use to calculate ranks. Its syntax is as follows: RANKX (<...

Different charts in Power BI

Image
  An overview of Chart Types in Power BI As everyone might be aware, Power BI is one of the SaaS offerings from Microsoft in the field of BI and Analytics. It provides a very intuitive way for non-technical users to do analyses and create reports on their own without having to rely on a technical team. One of the main purposes of Microsoft behind Power BI is to promote self-service BI and it is one of the BI tools in the market with a comparatively lower learning curve as there are many similarities compared to Microsoft Excel.  In this blog, I am going to give an overview of the most widely used chart types in Power BI.   Let's look at some of the most frequently used chart types in Power BI Bar and column charts Stacked Bar and Stacked Column Chart Clustered Bar and Clustered Column Chart Line Chart Area Chart Stacked Area Chart Line and Stacked Column Chart/ Combo Chart Line and Clustered Column Chart/ Combo Chart Ribbon Chart Waterfall Chart Funnel Chart Scatter Chart...

Modify DAX filter context in Power BI Desktop models

Summary CALCULATE  DAX function to modify filter context in the formulas. The syntax for the CALCULATE function is as follows: CALCULATE (<expression>, [[<filter1>], <filter2>]…) I learned about filter context. And also learned why and how to work with the CALCULATE function to modify filter context by passing in filters. These filters can add or overwrite the filter context, and they can modify filter context when we are passing in special functions like REMOVEFILTERS or KEEPFILTERS. Additionally, I learned that the CALCULATE function can transition row context to filter context, which can be required when we are using measure expressions in calculated columns or iterator functions.
