2019 Week 37: What percent of sales is from the east region?

This week we are making bar charts. Of course, this week there is a small twist to the bar charts. The ends of the bar charts need to be rounded. There are several ways to do this. I’d personally suggest unioning the data to itself–but like I said, there is more than one way to get to the solution!

Also, I wanted to work with accessiblity of parameters in Tableau. Given the static nature of parameters, there’s very little we can format to make the text truly accessible. I saw how Jacob Olsufka made this filter/parameter at the top of this visualization. Naturally, I use it all the time now. -LS

  • Format: 600px by 800px
  • Create a rounded bar chart that shows the percent of sales for each sub-category by the selected region of the dropdown.
  • The rounded bar charts should be overlayed on a second bar that goes to 100%. The color should be lighter tinted gray than the color you select for the main bar charts.
  • Integrate the Region dropdown in the title.
  • Place the percentage of the total at the end of the 100% rounded bar.
  • Match formatting–if you share on Twitter I’ll be looking out for this.
  • One more thing: this must be a single sheet.
