This week we will be looking at Sub-Category Sales by Month, and creating a highlight table of which sub-categories were the Max and Min Sales in that Month.Each Month will Highlight the MIN Sales in Red, Max Sales in Blue.Allow users to Filter by Year and/or Category.Pay attention to formatting and how the Table adjusts in size according to how many Sub-Categories are being shown.
This week we will need to use some formatting skills and the knowledge of formatting color. You’ll also be using the rarely-utilized hierarchy on this dashboard and you’ll need to utilize the “+” and “-” to drill in and out of the hierarchy.As you complete this example, feel free to share on Twitter using the #WorkoutWednesday hashtag. Don’t forget to tag @VizWizBI, @RodyZakovich, and @LukeStanke. We really want to see your work.
This week Andy is back with a challenge and it’s very straightforward. You need to create two quarters starting with the month selected and show months for everything else.As you complete this example, feel free to share on Twitter using the #WorkoutWednesday hashtag.
