Intro to Measures and Slicers

Check out Video #5 of Power BI Series and learn about DAX Measures and Slicers in Power BI Desktop.

This video covers:

  • How to create a Measure
  • Intro to Quick Measures and standard calculations
  • Intro to Slicers and Edit Interactions

If you are starting learning DAX I suggest:

  • Book:  Power Pivot and Power BI by Rob Collin & Avi Singh.  This was one of the first books I read about DAX.
  • Blog:  DAX Fridays  by Curbal.com . Ruth releases a video every Friday covering DAX functions (and more) and to date, the playlist counts with more than 80 videos.  Awesome work .

There are plenty of other sources (books, blogs, videos, etc), but these are my recommendations if you are new to DAX and Power BI and want to learn the basics.

DAX and M edition Helpers

We need to admit, the GUI for Power BI Formula Bar (DAX) and the Power Query Advanced Editor (M) are not the most user-friendly.
DAX editor (formula bar) is getting better but still quite limited. M editor (Advanced Editor) … OK, this might be something more advanced and eventually not everyone will need to write M functions.

But just in case if you are interested on it, these are my Helpers to write and format DAX and M code:

    • DAX STUDIO – “DAX Studio is a tool to write, execute, and analyze DAX queries in Power BI Designer, Power Pivot for Excel, and Analysis Services Tabular.” by SQLBI
    • DAX FORMATTER -“DAX Formatter is a free tool that transform your raw DAX formulas into clean, beautiful and readable code.” by SQLBI
    • POWER BI HELPER – “Export the Entire M Power Query Script from a Power BI File” by RADCAD
    • NOTEPAD++ – “Notepad++ is a text editor and source code editor for use with Microsoft Windows.” by Don Ho

My Stock Investment

Yes this is my other “hobby”.

I’ve built this report to track the performance of my investment in stocks.
As you may suspect it is something that I particularly care and for that reason this report is a real world scenario!
Due to privacy concerns I am only showing % weights and variations on the investments. But in truth, that’s the most important outcome of the analysis. Just assume x dollars and do the mats to convert it to  dollar amount

Technically, I’ve used a few distinct approaches to collect and transform the data for the report:

  1. Excel file located in OneDrive for manual input of my transactions;
  2. R Script to scrap daily prices online from Google (Quantmod package);
  3. HTML direct query Yahoo finance;
  4. Image URL method to display the companies logos (OneDrive repository);
  5. Parameter and Invoked Function to change the Proxy and automatically recalculate the figures;
  6. A bunch of measures with var … return if …, lookup table and others not so fancy but effective technics.

This still a work-in-process and I am planning to do a good piece of improvements. So not be surprise if it had changed meanwhile.
If you are interested to know anything related to this report and the technics I’ve used here,  just drop me an email or leave a comment below.

How to install Power BI

Installing Power BI Desktop is really simple and it’s FREE . Just go to https://powerbi.microsoft.com/en-us/get-started and download the latest version to your machine. Run the executable and boom 2. You are now empowered to create your own amazing reports.

The PBI desktop will be from now on your best companion and soon you won’t be using any other toll to do your analysis.

In more than 95% of the times you will already have a MS Office license in your Organization. Although if that’s not the case and you don’t have one licence you can sign up Office 365 for a 1 month trial.

Note: You will need to have a work or school email account to sign in into the Power BI Service or Power BI Mobile. More on that later. For now I suggest you start to discover the possibilities of the desktop version.

Sales KPI in one page

Sales KPI in one page

Here just an example of one page dashboard containing lots of information.
With Power BI it’s really quick and easy to create impressive presentations for that last-minute meeting with your client or boss. Yes, we all have been in that situation more often than we would like . Is exactly in that moments that PBI excels from the other BI and Analytics tools.

The agility you can build a report from the most untidy dataset, is not only going to save you lots of stress but also make you outstanding.
