One of the questions I normally get after presenting about aggregations in Power BI is that, does the aggregation works only for Composite mode and in scenarios to speed up the DirectQuery? or does it work in import mode as well? This article is about this question and shows how you can speed up your Read more about Aggregation to speed up the performance of a Power BI report even if all IMPORTED[…]
Anomaly detection is one of the popular topics in machine learning to detect uncommon data points in the datasets. For example, in a greenhouse, the temperature and other elements of the greenhouse may change suddenly and impact the plant’s health situation. Identifying the anomaly data in a credit card transaction, or in health data received Read more about Anomaly Detection in Power BI[…]
Regarding using Charticulator for creating custom visuals, I come across one of the visuals in the Charticulator gallery and I decided to follow it up to see how it created. So I manage to create a dataset that has ranking, name and amount. https://charticulator.com/gallery/co2_emission_ranking.html In this example, I am using Carbon dioxide emission data for Read more about Ranking Chart in power BI Desktop Using Charticulator[…]
I have written previously provided an all-in-one script for the date dimension, and also wrote an article about the relative date slicer. However, sometimes you cannot use the relative date slicer (timezone issue can be one example), adding offset columns help to overcome that challenge, and still be able to do flexible relative filtering in Read more about Offset Columns for the Date Table: Flexibility in Relative Date Filtering for Power BI[…]
Working with Power BI and Power Platform dataflows, or using Dynamics in general, might cause you to hear one of these two CDS (Common Data Services), or CDM (Common Data Model). Often there is a misconception about these two, and many people think they are the same. In this article, I’ll explain the difference between Read more about CDS and CDM are Not the Same! Difference Explained[…]
If you are using a date slicer in your Power BI report, a relative date slicer is one of the options to consider for sure. This is a very simple type of slicer to use, but very effective in terms of options that it provides for the user to slice and dice the data. Let’s Read more about Relative Date Slicer in Power BI; Simple, yet Powerful[…]
Recursive functions in Power Query are not very popular, but sometimes very helpful when in need. In this post, I’ll explain what a recursive function is, how it works, and explain it through a famous recursive example of Fibonacci Sequence. Fibonacci Sequence Fibonacci sequence is one of the fundamental recursive operations in math, below are Read more about Fibonacci Sequence: Understanding the Power Query Recursive Function for Power BI[…]
The ability to use Get Data from Folder in Power BI is a very useful option. However, if your sheet names are different in the list of Excel files, then you will face a problem. In this blog article, I’ll explain a method you can use that works regardless of the sheet names. Sample Dataset Read more about Get Data from Multiple Excel Files with Different Sheet Names into Power BI[…]
If you don’t have a date table with a column that represents the day of the week name (Saturday, Sunday, Monday etc) or number (from zero to six, or from one to seven), and you just have a date field, which you want to quickly get the day name of the week, here is a Read more about Get the Day of the Week Name and Number in Power BI Using DAX[…]
DAX is the analytical language in Power BI. Learning this language, however, comes with some difficulties. Part of that challenge is the way that functions work in DAX. Learning the output of functions is an important element of learning how and where you can use them. In this article, I’ll explain two types of outputs Read more about Power BI DAX Back to Basics: Scalar Vs. Tabular Functions[…]
