Therefore, this article will help you learn how to build a slope chart in Tableau using table calculation Rank. Using data on ‘Main roofing type’ in Kenya, I’ll demonstrate how to compare use of ‘Corrugated Iron Sheet’ and ‘Asbestos Sheets’ for different Counties within the country. Our goal is to rank Counties in order of using a particular roof type.

Connect data set above to Tableau app and follow along to learn more.

Step 1: Compute rank of ‘Asbestos Sheets’

Create the table calculation below,

Under ‘Default Table Calculation’ compute using ‘County’.

Step 2: Compute rank of ‘Corrugated Iron Sheets’

Repeated Step 1 above but now using measure field ‘Corrugated Iron Sheets’.

Step 3: Let’s build our chart

  • Drag the calculated field ‘Rank -Asbestos’ to the rows shelf.

  • Notice the field is highlight in red, this is because our rank field is computed along the ‘County’, to correct this, introduce the field ‘County’ to the details shelf. (Since, my field is a hierarchy, I will drag ‘Province’ out of the details shelf to remain with County only).

  • Drag calculated field ‘Rank -Corrugated Iron Sheets’ to the axis as show below.

  • Chose Line under marks card.

  • Right click on the axis>>Edit Axis… and reverse the axis.

  • Drag the measure field ‘Measure Values’ to the label shelf.

  • Select ‘Label’ shelf to open, edit as shown below.

Tableau slope chart final

From this view, comparison on use of Corrugated Iron Sheets and Asbestos sheets can be done with lots of ease. For instance, Nairobi county is ranked both No. 1 in use of the roof types, while Narok county is ranked No. 13 and No. 31 in use of Asbestos sheets and Corrugated Iron Sheets respectively. More insights can be draw without much strain.
