Open Data is like a soup

[2016-Nov-04] Open data is like a soup, some people like it hot (or made with all the latest updates); some people like it spicy (probably experimenting with various data representation forms). And only on some special occasions you'd prefer a c-old soup over a hot one (where old data analysis is…

Power BI with Narrative Science: Look Who's Talking (Part 2: Predicting the Future)

[2016-Oct-18] I read a book one time about the importance of using visual aids in teaching. They also used a well known illustration that a human optic nerve is thicker than the auditory one; thus, resulting to more information being consumed by brain with seeing things rather than hearing or listening to…

Historical Reports vs. Predictive analytics: Rear view mirror look vs. Forward-looking view. Really?

[2016-Sep-30] Working with reports based on historical data is like driving a car while looking in the rear view mirror. I heard this term again when I went to the Microsoft Data Science Summit in Atlanta (https://ignite.microsoft.com/microsoftdatascience) this past week. Which gave me a second thought to consider: how…

Power BI with Narrative Science: Look Who's Talking?

[2016-Aug-31] Someone said a picture is worth a thousand words and this is true that in most cases a visual representation of a fact is absorbed better compared with a verbal or textual version of it.  However sometimes just looking at a “picture” or analytical report it also would be…

Power BI Pulse Chart vs. Dancing bars in Excel

[2016-Jun-30] Recently Microsoft Power BI has been enhanced with a new Pulse Chart custom visualization (Visual Awesomeness Unlocked: Pulse Chart) which is extremely good and useful for a visual data story telling. I believe that the less we have people explaining their data visualization and more we let…

Analyzing David and Goliath datasets on a same chart; Dual Axis in Excel, Power BI and SSRS

[2016-May-31] Two different metrics, two different datasets, one may represent a very high value and the other one is very low. What's interesting is that both metrics could be very close related; like Total Product Sales vs. Product Price or Average Monthly Temperature vs. Rainfall over a period of time.

Power BI Box and Whisker visualization vs. Box Plot chart in SSRS

[2016-Apr-30] I don't work with box plot charts very often, however when I do then it becomes a very interesting experience. First, it starts from data extraction and then playing around with various visual settings to make those boxes and whiskers to look good.

I assume that sometimes we tend to work…

Excel Power Map vs. Power BI Globe Map visualization

[2016-02-02] PowerMap in Excel is a great tool with good design and comprehensive user experience. I’ve started using it about a year ago when our team participated at first Canadian Microsoft Big Data hackathon (http://blogs.technet.com/b/cansql/archive/2015/04/13/big-data-hackathon-a-story-from-a-winning-team.aspx).

So I gradually developed a taste to this Geo analytical tool…

Specifying Paths to External Items (Report Builder and SSRS) in SharePoint with PowerShell

[2015-Dec-24] My story: two SSRS items (main report and its sub-report) need to be deployed to SharePoint. Trivial task, and even if I need to locate sub-report to a different SharePoint document library or folder I can easily do that during a development phase or using Report Builder…

Too Big To Be Visible - SQL Server vs. Oracle data in SSRS reporting

[2015-Oct-20]  A sourcing system failed to return correct results (returned value was a very high figure with double digit number after "E"). An existent ETL process was capable to save this value into an Oracle staging database, however previously working SSRS report showed me a blank column with no data…

Why I still like Excel PowerPivot models in SharePoint however Tabular solutions in SSAS are better

[2015-Aug-12] It’s quite obvious that in present time there is a growing audience for all the latest changes and updates within the Microsoft Power BI sphere. I think someone has already built a data model that showed number of tweets about Power BI which prevailed other more usual and heavily…

Single value filters and custom error messages in Power BI

"Let me be the one for you, otherwise we need to work on communication". Basically this was a very brief description of a recent use case for a power view report which had been later replicated in a Power BI slide as well.

Users were aware of PowerView / Power…

Setting specific colors for PowerView charts

I was listening for Phil Collins' "True Colors" song in my car audio this morning and it reminded me about the very issue that PowerView currently has: that it doesn't allow to set specific colors to different elements of its own visuals. There are more and more announcements made about…

Big Data Hackathon in Microsoft Canada: Power Map will find your way!

Big Data, what a term! Some people instantly think of a huge sometimes cumbersome volume of information, others define it with three or four Vs (volume, velocity, variety, and variability).

SSRS report footer is NOT lost in Excel

With all the recent changes and updates within the Microsoft PowerBI universe, SSRS core technology gets less and less attention. However a recent experience with one of the SSRS report’s functionality triggered my interest to share it.

PowerPivot Saga 2: DAX OR function (OR there is something better)

I didn't realize that the DAX OR function only accepts 2 arguments compared with the similar function in Excel where a limit of arguments is set to 255. This difference only occurred to me when I received an error in my PowerPivot data model with an attempt to list more than 2 arguments…
