Quick Tips: How to Sort Matrix by Column in Descending Order

How to Sort Matrix by Column in Descending Order

Today Microsoft released Power BI Desktop March 2020 which I was hoping that it includes a simple feature on Matrix visual to be able to sort the Martix by column in descending order, but, it doesn’t. So, in this post I quickly show you how to sort Matrix by column in descending order.

Here is the scenario. One of my customers is building a report in Power BI showing sales by Year, Month and Day of Week in a Matrix as below.

Everything looks fine! But looking at the Matrix sorting quickly reveals that such feature is NOT available (YET). But the customer would like to see the Matrix sorted by Year in descending order, something like this.

Here is the solution which is super simple.

Empower Your Story Telling Data Visualisation in Power BI with Colour Coding

Colour Coding in Power BI

This post has been waiting in my blogging list for a while and now this is my last post in 2019. I wish you all have a wonderful year ahead.

In this post I discuss a very important aspect of data visualisation; Colour Coding. I believe, colour coding is one the most powerful and efficient ways to provide proper information to the users. We learnt as human being that the colour can tell a lot about things. For instance, we look at green grass, if it is light green we immediately understand that the grass is quite fresh and healthy. When she gets a bit yellowish, we know that she’s perhaps thirsty. When it gets brown it is probably too late.

Another perfect example is traffic lights. When it is green, everyone is happy, when it is yellow, everyone is racing to pass the junction, well, I’m just kidding, some people tend to pass the yellow light while everyone knows they have to stop when traffic light is yellow right?? And… when it is red, we have to stop. Enough saying about colour coding and its affects on our lives on a day to day basis. Let’s talk about colour coding in Power BI and quickly get to more exciting stuff.

So… colour coding in Power BI, well, we could colour code from the day first that Power BI born, but, perhaps not in a way that I’m going to explain in this post. Conditional formatting is also around for a while now. In this post I show a technique that we can implement in Power BI to use a consistent colour coding across the whole report.

Here is a report without colour coding:

And now look the same report that is colour coded:

 Colour Coded Power BI Report

Let’s get into it.

Getting Started

In this technique we’ll follow the steps below:

  • We jump online using some awesome free colour palette websites to generate the colours we’d like to use in our reports
  • We copy the HEX values and paste into Power BI (via Enter Data)
  • We define a range of numbers to identify the ranges that our values will fall into. I personally use percentage, but it might be something else in your case
  • We then define some measures to pick a specific colour for the measures we want to colour code

Good Practices: Always Display the Reporting Environment

Good Practice: Always Display the Reporting Environment

When you work on real-world projects in power BI, you would probably have different environments Like DEV, UAT, Pre-Prod and Prod. It is important for you and your audience to know what the data is coming from. Am I looking at Dev or UAT data or I am actually looking at real data in Production environment. You may have asked or been asked with a question like “Where the data is coming from?”. It is important to know how trustworthy the data you’re analysing is. In this post I show you an easy way to show the environment your Power BI report is connected to.

How It Works

To display the environment name you use query parameters, then you reference that parameter, turn it to a table and add columns to show the environments accordingly. Easy right?

Read more about query parameters from a list output here.

Depending on your scenario the implementation might be slightly different, but the principals are the same. In this post I use a SQL server database. Therefore I need to Parameterise server name. in real world you may also need to parameterise the database name. Again, if your case is quite different, like if you get data from Excel, then the Excel path can be different for different environments. Let’s dig-in.

  • Open Query Editor
  • Click “Manage Parameters”
  • Click “New”
    • Enter “Name” and “description”
    • Tick “Required”
    • Select “Text” in “Type”
    • Select “List of values” in “Suggested Values” and type in server names for different environments
    • pick a “Default Value” and “Current Value”
    • Click OK
Creating new parameter in Power BI Query Editor

So far you created a new parameter that can be used to get data from a SQL Server data source.The next steps show you how to use that parameter to show the environments in your reports.

Quick Tips: Export Power BI Desktop and Power BI Service Model Data In One Shot with DAX Studio

Exporting Model Data to CSV 
or SQL Server in One Shot

In some of my old posts, which are most popular ones, I explained how to Export data Power BI Desktop or Power BI Service data to different destinations like CSV, Excel and SQL Server. In this quick tip I explain a very easy way to export the model data as a whole to either CSV or SQL Server with DAX Studio.

Daniil from XXL BI well explained this method, but I’d rather quickly explain how it works and add some more information.

After release 2.8 of DAX Studio, you can now quickly export the whole model to CSV and SQL Server in one shot.

Enabling Export All Data in DAX Studio

  • Open DAX Studio
  • Click “File”
  • Click “Options”
  • Click “Advanced”
  • Tick “Show Export All Data button”
