Option 1: Use a custom background image

See Use Background Images in Your Views for directions. Please note, this option is not dynamic, meaning if the parameter values change, the background will have to be manually adjusted.

Option 2: create a dual axis chart, where one axis is polygon marks to fill the quadrants

1. Join the attached "quadrant scaffolding.xlsx" to the existing data source with a FULL OUTER join. For the linking field, create a join calculation in both the left with the value 1, and use "Dummy Linking Field" from the right table.
2. Create a calculated field with a name like "x values" with a calculation similar to the following: MIN(
IF [Quadrant] = "data"
THEN { FIXED [Customer Name] : SUM([Profit]) }
ELSEIF [Quadrant] = "lower left"
OR [Quadrant] = "upper left"
THEN
    IF [Corner] = 1
    OR [Corner] = 2
    THEN { FIXED : MIN( { FIXED [Customer Name]: SUM([Profit])})}
    ELSE [x-axis parameter]
    END
ELSE
    IF [Corner] = 1
    OR [Corner] = 2
    THEN { FIXED : MAX( { FIXED [Customer Name]: SUM([Profit])})}
    ELSE [x-axis parameter]
    END
END
)
3. Create a calculated field with a name like "y values" with a calculation similar to the following:
   
   MIN(
IF [Quadrant] = "data"
THEN { FIXED [Customer Name] : SUM([Sales]) }
ELSEIF [Quadrant] = "lower left"
OR [Quadrant] = "lower right"
THEN
    IF [Corner] = 1
    OR [Corner] = 4
    THEN { FIXED : MIN( { FIXED [Customer Name]: SUM([Sales])})}
    ELSE [y-axis parameter]
    END
ELSE
    IF [Corner] = 1
    OR [Corner] = 4
    THEN { FIXED : MAX( { FIXED [Customer Name]: SUM([Sales])})}
    ELSE [y-axis parameter]
    END   END )
4. Create a calculated field with a name like "Data Points" with a calculation similar to the following:
   
   IF [Quadrant] = "data"
THEN [Customer Name]
END
5. Drag [x values] to the Columns shelf
6. Drag two copies of [y values] to the Rows shelf. This should create two scatter plots, each with a single point, one on top of the other. There will now be three Marks cards: All, AGG(y values), and AGG(y value).
7. Click on the first copy of AGG(y values) on the Rows shelf to open its corresponding Marks card.
8. In the dropdown, change the mark type from Automatic to Polygon.
9. Drag [Quadrant] to Color on the Marks card.
10. Drag [Corner] to Path on the Marks card.
11. Click Color and click the Edit Color… button to change the colors as desired.
12. Click on the second copy of AGG(y values) on the Rows shelf to open its corresponding Marks card
13. Drag [Data Points] onto Detail.
14. Right-click the second copy of AGG(y values) on the Rows shelf and check Dual Axis.
15. Right-click either y-axis in the view and check Synchronize Axis.
16. Right-click the second copy of AGG(y values) on the Rows shelf and uncheck Show Header.
