Build awesome dashboards for mobile and desktop using Datazen
Datazen is a great visualization tool that is free to Microsoft SQL Server Enterprise customers. If you haven’t worked with Datazen yet, check out this post by Rob and Chris! Datazen allows you to design an awesome dashboard before you even work with any data! You simply draw a visualization, and then Datazen reverse engineers the exact layout of the aggregate table that you need in order to make that visualization work.
If you already have a PowerPivot model that you use for reporting, naturally you’ll want to use it to build visualizations in Datazen rather than reinvent the wheel entirely. One way to incorporate your dozens or even hundreds of measures and model logic (not to mention dozens of hours) into Datazen visualizations is through DAX queries.
Two Paths to Datazen DAX Query Nirvana…
Ok, you’ve built a fantastic BI dashboard in Datazen and your chakras are perfectly aligned. Now, there are two enlightening paths that you could take to build tables for Datazen visualizations with DAX queries:
A) Create a new ‘Data Connection’ in Datazen to your PowerPivot model hosted on SharePoint/SSAS Tabular, using the Analysis Services Data Provider. You can automate the refresh of data with SharePoint/Power Update and in Datazen itself.
B) Query your Power Pivot model using DAX Studio and save the workbook to a One Drive folder, then import the data into Datazen. This process can also be automated using Power Update.
Let’s take a closer look at both of these methods, starting with a SharePoint hosted Power Pivot model.
