Show Total When Nothing is Selected in Matrix Table

[kushanNa]

✅ Why this blog?
As of now, I couldn’t find a solid blog or solution that clearly addresses how to show total values when nothing is selected from a Matrix Table .Since this is a frequent question in the Power BI community, I decided to write this step-by-step guide to help others looking for the same solution.

Step 1: Create a new support Table

Table B = 
UNION(
    DISTINCT(SELECTCOLUMNS('Table A', "Product", 'Table A'[Product])),
    ROW("Product", "All")
)

Step 2: Create Relationship

Go to Model view and create a relationship:

• From: Table A[Product]
• To: Table B[Product]
• Cardinality: Many to one (Table A → Table B)

✅ Make sure this relationship is active.

Step 3: Create Measures

1️⃣ Sales Measure (Total or Filtered)

This measure checks the selected product. If "All" is selected, it returns total sales. If a specific product is selected, it filters accordingly.

Sales Measure = 
VAR CurrentProduct = SELECTEDVALUE('Table B'[Product])
RETURN
    IF(
        CurrentProduct = "All",
        CALCULATE(
            SUM('Table A'[Sales]),
            ALLEXCEPT('Table A', 'Table A'[Region])  
        ),
        CALCULATE(
            SUM('Table A'[Sales]),
            'Table A'[Product] = CurrentProduct
        )
    )

Selection Flag (For Visual Filter)

This measure ensures the correct rows appear in your visuals:

Selection Flag product = 
IF(
    ISFILTERED('Table A'[Product]),
    IF(
        SELECTEDVALUE('Table B'[Product]) = SELECTEDVALUE('Table A'[Product]),
        1,
        0
    ),
    IF(
        SELECTEDVALUE('Table B'[Product]) = "All",
        1,
        0
    )
)

Step 4: Create the Stacked Bar Chart

1. Insert a stacked bar chart
2. Create a Matrix table with Table A Columns Product, Region, Sales  
3. Set up the fields:
• Y-axis → 'Table B'[Product]
• X-axis (Values) → Sales Measure
• Legend → 'Table A'[Region]

🔎 Step 5: Apply Visual-Level Filter

To make sure only the selected product (or total) is shown:

1. Select the chart.
2. Drag the Selection Flag product measure to the Visual-level filters pane.
3. Set the filter to "is 1".

🛠 Edit Interactions

1. Select the Matrix table.
2. Go to Format > Edit Interactions
3. For each visual:
• Choose Filter (✅) to apply slicer

✅ Result

• Selecting nothing → chart shows total sales for all products, split by region.

Nothing Selected

Values selected
