I’ve recently discovered Power BI. Basically, it’s the child of Power Pivot and SQL Reporting Services, but without Kryptonite to slow it down. You can connect to all kinds of datasources – Excel, SQL, Hadoop, folders ….and 55+ other data sources – and then perform analyses of the data therein. Microsoft has even allowed developers to publish / create new “visualizations” (charts, graphs, maps, etc.) for users to adopt for their data analysis.
I decided to give it a try, and used my Wine Cellar Excel spreadsheet as the
test data set so I could more easily recognize any trends that the
Visualizations pointed out.
I first evaluated my collection by Country & Region by Quantity of Wine
(in ml). The light blue circles correspond to “France”, and the pink is
“Portugal”…Somehow Burgundy, France wound up near New York…and our Douro,
Portugal (Port!!) sat near the Great Lakes. This I cannot explain.. .I had to
edit “Rhone, France” to “Lyon, France” to move it from somewhere in Asia to
France. I’m not sure how it was handling the mapping, but I guess it cannot handle Region names.
The only way I could get the mapping to look better was to look up the regions
and set them to specific cities in each country. I guess that the mapping
program cannot understand Regions (Bordeaux, Burgundy, Cotes D’Or, Willamette
Valley, Douro Valley, etc.). Therefore, if one wishes to use Power BI to display
data on maps, then the locations listed must be City names, and not Region
names, nor a mix of Cities and Regions as I had in my Wine List spreadsheet.
I then tried and analysis of Quantity (in ml) by Year and Appellation. This
provided the expected results: we own a LOT of Chateauneuf du Pape 2005 (Pink in below graph).
I also evaluated it using the pie chart to see how that turned out.
Again, it’s obvious what we like to stock in our wine cellar (light blue is all 2005, and the majority is Chateauneuf du Pape), but it also
shows that Power BI makes it extremely simple to illustrate that fact through
the visualizations it provides - I spend only a few minutes to generate these charts from my data.
All in all, I’d say that Power BI is very useful for quick and efficient analysis of any dataset
where a graph or chart would best illustrate the relationship of data elements
