Labeling data visualizations clearly is important. In addition, all relevant data should be presented. The data visualizations focus on the dollar amount of sales revenue. Another important statistic for management is total cases sold. Add total cases sold to the bottom of the dashboard after the Total Sales Revenue amount. Why might management want to know total cases?

Another technique to analyze categorical data is to create a bar chart. Add an additional Tableau sheet with a bar chart showing the breakdown of sales by beer. Add proportions of sales revenue as labels. Sort the bars from largest to smallest sales. Use product description for colors with a legend defining each color. Add the title with Today$$s Report Date in red:

Sl$$inte

Report Date:
