To create a line and clustered column chart in Power BI with the measure "Sales" and dimensions "Category" and "Subcategory", along with a reference line showing average sales within each category and color the bars above this line with a different color using DAX, you can follow these steps:
Ensure that you have the necessary data imported into Power BI and the desired measures and dimensions added to the fields pane.
Click on the "Insert" tab in the Power BI ribbon.
Select the "Line and Clustered Column Chart" visualization from the "Visualizations" section.
Drag the "Category" dimension to the "Axis" field well.
Drag the "Subcategory" dimension to the "Legend" field well.
Drag the "Sales" measure to both the "Column values" and "Line values" field wells.
Right-click on the "Sales" measure in the "Column values" section and select "Add Average Line" from the context menu.
In the "Visualizations" pane, click on the "Data colors" section.
Enable the "Conditional formatting" option.
Set the "Based on field" to the "Sales" measure.
Set the condition to "Above".
Choose the desired color for the bars above the average line.
To ensure that the reference line shows the average sales within each category, you need to create a DAX measure for the average sales by category.
Go to the "Fields" pane and click on the table containing the sales data.
Click on the "Modeling" tab in the Power BI ribbon.
In the "Calculations" group, click on "New Measure" to create a new DAX measure.
In the formula bar, enter the following DAX formula to calculate the average sales within each category:
DAX
Copy code
Average Sales by Category = CALCULATE(AVERAGE('Table'[Sales]), ALLEXCEPT('Table', 'Table'[Category]))
Replace 'Table' with the name of your table and 'Table'[Sales] with the correct column reference for your sales measure.
Now, the reference line in the line and clustered column chart will display the average sales within each category, and the bars above the line will be colored differently based on your conditional formatting settings.
By following these steps and creating the DAX measure for average sales by category, you can create a line and clustered column chart in Power BI with a reference line showing the average sales within each category and color the bars above this line with a different color.
