Introduction
I’m trying out some new chart types in this week’s Workout Wednesday. Recently Tableau introduced the ability to create variable width column charts (sometimes called skyline charts – because they can look like a city skyline). I wanted to get an appropriate and interesting data set for this challenge. I found some data on journey times to UK airports from Lower Super Output Areas from data.gov.uk. Pretty interesting! I supplemented that by joining on lookup tables to aggregate the data up to local authority level – something most people in the UK would recognise as a geography. I also added some additional data about the airports – numbers of passengers and destinations.
Requirements
- My dashboard size is 800*600
- Make sure you match my titles, colours and tooltips
- Enable users to filter down to a specific local authority
- Exclude airports with less than 100 destinations
- The width of each column is the average drive time (for all times of day) to the airport from the selected local authority
- The y axis is the number of weekly direct destinations for the airport
- Colour the bars depending on whether they are in or out of the number of minutes the end user would like to drive for
