Today is day 3 of Dashboard Week! The challenge for today was to create a visualisation in Power BI. We were given an interesting dataset based on the Titanic. I decided to focus on survival rates, particularly for children. I wanted to visualise differences in survival rates based on age, gender and class. I created two similar dashboards, one as an overview and the second focusing specifically on child survival rates.
We were instructed to include the following features in our dashboard.
- Merge Join/s
- Edit Queries
- DAX Formula/s
- Custom Visual
- Interaction
- Bonus – Parameters!
The experience of working in Power BI after spending so much time using Tableau was very challenging. Initially, I found joining the data quite straightforward. However, most other features feel much more intuitive in Tableau. For example, I found using a DAX formula a lot more complicated than any Tableau calculations I’ve done before. On the other hand, it was fun to play around with Power BI’s custom visuals as there are a lot more chart options than in Tableau. There are also some formatting options that I found easier in Power BI such as aligning objects on the dashboard.

Although I enjoyed spending the day analysing an interesting dataset with Power BI, I still much prefer using Tableau!
