Are you trying to get your head around Filter context in DAX? I watched a video from the sqlbi.com guys and it explained it well. I thought I could add an Excel flavour to it.

Creating a Unique Dynamic List in Excel
A Power Query technique
There are a couple of techniques to automate a unique list of items in Excel. I have covered them in previous blog posts (see links below). I thought I would describe how to use Power Query to create a dynamic unique list.

An Avo Chart
I wonder if we can get one of these on Power BI?
Saw this on the website below and liked it – I also like Avocados.

If you are into statistics then you probably already know about the R language – but if you don’t it may be worth looking at.
It is open source code that is built to handle statistics and big data. It has some limitations when used with Power BI but it can be used on its own.
This article looks at using visuals created with R in Power BI.
DAX is the function and query language of PowerPivot and PowerBI. It has been around for a while, but it didn’t really have many editing tools until DAX Studio came around.
DAX Studio has been created by the SQLBI.com guys – the legends in PowerBI.
I saw a demo today at the Perth Modern Excel User Group at Microsoft Perth – its great.
Whilst it is a powerful editor, it is not just a code editor.
There are lots of options to allow you to optimise your DAX code. Lots of output options as well.
You can test and see how long it takes to run your DAX commands.
If you regularly use DAX in Power BI or PowerPivot then DAX Studio is a must have.

Compare the offerings of the Free vs Pro versions of Power BI.
The Pro version costs about AUD10 – 15 a month.
Thanks to Gilbert Quevauvilliers for creating the infographic + sharing.

Some great tips on language usage with DAX and the M language in Power Query with examples and explanations.
You can download pdfs.

Ability to connect to the Power BI dataset and the ability to create a Query based on an example column. Interesting times ahead.
Quick measures also added.
Power Query (Get & Transform) uses the M language to allow you to customise and build in flexibility to your queries.
Currently writing the M language is tricky to write. It is case sensitive and there is no built-in help to assist you using the language.
Apparently Microsoft is working on creating an M editor, but there is no time line on when it will be ready.
This article takes you through some steps to create your own editor using Notepad ++.
If you use Power Query a lot then this may be worthwhile.

There is a new Matrix Visual report with more options. It has a separate icon so you can compare to the existing Matrix.
The new Numeric Range slicer looks interesting too.

Well after getting the data and creating a report and then a chart, let’s get the report onto the web.
