Birra Bellazzi management asks:
“How have our beers performed since the beginning of the year?”
This is quite a standard question!Product performances are usually defined by 3 KPIs: Revenues Budget Last Year

Approach #1
Starting with the standards:- Insert a default Bar Chart
I don’t like this view!It is too difficult to understand
Although I will probably change the overall approach I will try to fix the Legend.

LEGEND tip
- Remove the legend- Embed legend colors within the title
Still, I don’t like this view!Three bars in the same chart make it too difficult to understand.
I need a different approach.
What do I have:- 3 KPI- REVENUE is the main one- BUDGET & LAST YEAR are supporting KPI

Approach #2
- 3 KPI probably means 3 charts
- I try with 3 aligned bar charts
- This time I use the % values for Budget and Last Year
I like this solution way better!i.e.- CALABRIFORNIA performed way better than expected and Bellazzi was able to improve the results for this beer.- ALLEY HOP is under budget but it is 2% up compared with last year: something went wrong with the budgeting phase
@sandolinic
Approach #3Want they want is to understand if a Beer:- reached its budget- performed better or worse then last year
Maybe a Bullet Graph is the solution I am looking for!
Compared with previous approaches:- It provides the same information- It takes less space
Issues:- Not many BI tools can draw it- No horizontal bullet graph with Excel
