One of my favorite chart types is a dot plot/strip plot. There’s something really special about dots displayed across a single horizontal or vertical axis. They tend to work really well when you’re showing a lot of data and have the advantage of being able to compare spread and density across different categories within a dimension. To enhance the dot plot, I wanted to take some time for this workout and try out a few additional data encoding techniques. The real “use case” of this particular visualization showing manufacturer sales & profitability by sub-category may not be the best translation, but I’m confident there’s a business use case out there for this chart!
So for the workout this week, you’ll be asked to add on additional encoding and enhance the dot plot beyond the default. You’ll have the size of the dot represent Sales and use color in 2 different ways: first to re-encode Profit Ratio and also as a way to demonstrate the top performer within a Sub-Category. You can expect some common design elements from me – including dynamic tooltips based on the data, upper case words, and non-default headers.
- Dashboard size: 1200 x 1300; you choose the # of sheets
- Create a dot plot that shows Profit Ratio and Sales by manufacturer and sub-category
- Profit Ratio on the X-axis and on color
- Sales on size
- The top performing manufacturer within each sub-category should have a black bottom-half to and label
- Watch out for the tooltip flavor text on the top performers
- Color scale is Color Brewer Red, Yellow, Green (-1 to 1) – if you don’t already have it, download via Jacob Olsufka’s Tableau Public
- Create headers for the sub-categories that extend into the data area
- Add on a Region filter and ensure your headers match the data when you filter
- Sort the data appropriately (sub-category by profit ratio)
- Match any final formatting/tooltips (I went pretty easy on you this week!)
This week uses the superstore dataset for Tableau 2019.1. You can get it here at data.world
When you publish your solution on Tableau Public make sure to take the time and include a link to the original inspiration.
