Since 2016 there’s a built-in feature in Power BI that allows us to automatically find cluster within our data.This is a great feature, however, its main drawback is that whenever we add new data into Power BI the clusters need to be manually recalculated for the new data. In this post, I will show how we can implement clustering in Power BI using R and automatically recalculate the clusters whenever we hit the refresh button. What is Clustering Clustering is the…
In this post, I share how to perform a bootstrap analysis with Power BI and briefly introduce what is bootstrapping and when to use it.
In this short post, I show how we can integrate a data dictionary using DMV queries within an SSAS tabular model and why we should do so. Why should we have a Data Dictionary within our model? The more complex a model becomes the more documentation we need to have about it. The more measures and complex formulas we have in a model the more calls/questions we have from end-users and thus the less time we can spend on getting…
In Power BI Desktop with Query Editor we can perform advanced custom transformation using Python or R script.
In this short post, I show how we can pass parameters to python script.
As of now, in the Power BI Line and Clustered Column chart, we cannot Combine Clustered Columns with Clustered Lines or Markers.
In Power BI the markers all line up over the middle of the cluster instead of overlaying every single column.
So in this short post I share how to create such a visual using R.
A/B testing, or split testing, is a digital marketing technique that involves comparing two versions of a web page or application to see which performs better.
In this post, I am going to share a step by step guide to implement AB Testing with Power BI.
By now there’s plenty of good tutorials that explain how to create your own visualisations in Power BI by using R or Python like the Microsft one here.However, I haven’t seen any articles on how to create dynamic visuals by using Python (or R).So in this post I’m going to show a very simple and fast way to create your power bi visuals by using python. (Same can be done using R) Goals of this Post Create visuals by using…
Now it’s been a year since the game-changer new calculation groups feature has been released and I just thought that I still haven’t written a post on it. Goals of this Post Use Calculation Groups Use Tabular Editor Advanced Scripting Speed up SSAS/PowerBI model development Create reusbale script Setting up the Environment Power BI: Download here. Tabular Editor: Download here. SQL Server 2019 and later Analysis Services or Azure Analysis Services. At the time of writing this post Caclulation Group…
I first thought that the recent calculation group feature wasn’t working in a matrix when selecting more than one calculation item from a slicer, until, I realised that all I had to do to fix it was to simply disable the “column subtotals” option. To be honest I find the error message shown by PBI misleading. So if you encounter the error”Time Calculation Requires selection of exactly one calculation item” here is what you have to do to fix it:…
In this post, using Power BI I’ll try to uncover some useful insights and demonstrate that using the appropriate visuals help to analyse data more efficiently.
I’ve previously written an article on how to dynamically convert and change the currency of a measure using a slicer.Now let’s see how we can dynamically format a measure by still using a slicer. Model Prerequisite Add the FormatString column into your currency dimension You can download the file with the sample format string from here.Make sure to use a Unicode type column to store the different format strings otherwise the collation of your DB might not support all the…
A common scenario in multinational companies is having to integrate different currency rates across transactional data.
So here is how we can convert and display data in different currencies in Power BI in a few simple steps.
