#WorkoutWednesday wk 33 – What Customers make up XX% Sales?

Community #WorkoutWednesday challenge this week was set by Donna Coles and it was about Pareto chart with certain twists. Here, Requirement was to create Pareto chart to see what proportion of customers make up sales with an option of sliding parameter and few tooltips to make it user friendly along with ease of understanding.

Requirements: 

  • Dashboard 800 x 800.
  • Selection of the Sales Percentage slider will adjust the highlighted point.
  • Sales Percentage slider should increment in 10s from 10%-90%.
  • % values displayed to 1 decimal point.
  • The Sales Percentage mark highlighted should be the value that is at least the value selected in the slider (eg when 60% is selected, the mark highlighted is 60.1% as the previous mark is 59.9% which is less than the slider value).
  • The tooltips on the curve differ from that on the highlighted mark.
  • The tooltip on the highlighted mark should also indicate the actual number of customers at that point, as well as the total number of customers.
  • Rebuild everything to be identical, matching titles, tooltips, chart formatting.

Here is my output for the challenge (Click on gif for interactive version):

Here are the steps which I undertook to create this dashboard and complete the challenge

Step 1: Create the Parameter as per requirement to select Sales %

Step 2: Create calculated fields required to create the visualisation and calculations

My attempt was to create the dashboard with minimum steps. I created 6 calculated fields + 2 copies of calc fields

% of customers: On X-axis we need to show the running % for distinct customers

% of Sales: on Y-Axis we need to show running % for sales

Customer Point: This field is to show “% of customers” when “Sales %” is >= “% of Sales” field

Dot: Here we will use lookup function to find previous value of “Customer Point”. This field is to circle the position and highlight % of customers basis of % of sales (if 80% sales is selected then to show point at 49.9%)

Fixed Customers: This field to count the distinct number of customers

Sales Point: This field was more of after thought after re-looking at the requirements. This field we will show “% of sales” when “Sales %” is >= “% of Sales” field (if 80% selected then to show 80.1%)

Then, duplicate the “% of customers” and “% of Sales” Field for the purpose of tooltip and format this with 1 decimal point.

 

Step 3: Create the Sheet for the viz

Drag “% of Customers” and “Dot” field to column shelf then drag “% of sales” to row shelf

Select Customer Name and drag that field to details in Marks area then sort the field descending by sales

Select the graph type as “Area chart” for “% of customers” and “Circle” for “Dot” Field

Now, select “Dual Axis” on Dot field on column shelf then synchronize the axis and remove the “Measure Names” from color shelf

select “Grey” color for the area chart and “Black” color for circle Chart

For the reference lines on sales & customer, drag “Customer point” and “Sales Point” to Marks area

Right click on Y-axis and select add reference line, then select sales point from drop down and set as minimum

Similarly, Right click on X-axis and select add reference line, then select Customer point from drop down and set as minimum

Post this step, your viz is ready and will look like this:

Tooltip: drag “% of sales” , “% of customers”, “Fixed customers” into marks area for “Dot” field and additionally we will have distinct count of customer id on the basis customer name then we will modified the tooltip to see our requirement

Format the sheet and clean it up to meet the requirements and add the sheet into dashboard with few cosmetic changes.

And we are ready with final visualization as show above.

  • Great post as always!
    But I have one question – do you think it’s possible to add coloring of the area to the left of the ‘% of customers’ reference line? That would look nice as well I think. I tried to come up with some solution but it seems like I wasted my time to no effect in this matter when it comes to achieving this effect…

  • Worthful Tableau tutorial. Appreciate a lot for taking up the pain to write such a quality content on Tableau tutorial. Just now I watched this similar Tableau tutorial and I think this will enhance the knowledge of other visitors for sure. Thanks anyway.:-https://www.youtube.com/watch?v=Ny6h82Qy4tA
