DAX for Power BI videos | DAX for Power BI Part 2.4 - Working with Blanks
Posted by Andrew Gould on 21 August 2021
This video shows you how to work with blanks in your DAX expressions for calculated columns. You'll learn you to test for blanks using the IsBlank function and the Blank function. You'll see the difference between the equal to and strictly equal to operators and the importance of that difference when it comes to working with blanks. You'll learn how to produce a blank as the result of an expression and what happens when you involve a blank in some basic arithmetic. Finally, you'll see how to concatenate a blank into a string and how to use the Coalesce function to produce a replacement value.

Making a video bigger
You can increase the size of your video to make it fill the screen like this:
Play your video (the icons shown won't appear until you do), then click on the full screen icon which appears as shown at its bottom right-hand corner.
When you've finished viewing a video in full screen mode, just press the Esc key to return to normal view.
Improving the quality of a video
To improve the quality of a video, first click on the Settings icon:
Make sure you're playing your video so that the icons shown appear, then click on this gear icon at the bottom right-hand corner.
Choose to change the video quality:
Click on Quality as shown to bring up the submenu.
The higher the number you choose, the better will be your video quality (but the slower the connection speed):
Don't choose the HD option unless you have a fast enough connection speed to support it!
Is your Wise Owl speaking too slowly (or too quickly)? You can also use the Settings menu above to change your playback speed.
