Semantic Query Format

The query object binds visuals to data. Key concepts:

Field Reference

{
  "field": {
    "Column": {
      "Expression": { "SourceRef": { "Entity": "TableName" } },
      "Property": "ColumnName"
    }
  }
}

Measure Reference

{
  "field": {
    "Measure": {
      "Expression": { "SourceRef": { "Entity": "TableName" } },
      "Property": "MeasureName"
    }
  }
}

Query Buckets

Bucket	Used By	Purpose
`Category`	Charts	X-axis grouping
`Y`	Charts	Y-axis values
`Series`	Charts	Legend grouping
`Values`	Cards, Tables	Data fields
`Rows`	Matrix	Row headers
`Columns`	Matrix	Column headers
`Tooltips`	All	Hover information

Filters

Visual-Level Filter

{
  "name": "Filter123",
  "expression": {
    "Column": {
      "Expression": { "SourceRef": { "Entity": "Products" } },
      "Property": "Category"
    }
  },
  "type": "Categorical",
  "filter": {
    "Version": 2,
    "From": [{"Name": "p", "Entity": "Products", "Type": 0}],
    "Where": [{
      "Condition": {
        "In": {
          "Expressions": [{"Column": {"Expression": {"SourceRef": {"Source": "p"}}, "Property": "Category"}}],
          "Values": [[{"Literal": {"Value": "'Electronics'"}}]]
        }
      }
    }]
  }
}

Page-Level Filter

Add to the page's filters array using the same structure.

Conditional Formatting

Data Bars

{
  "objects": {
    "values": [{
      "properties": {
        "backColor": {
          "solid": { "color": { "expr": { "Literal": { "Value": "'#E8E8E8'" } } } }
        }
      }
    }]
  }
}

Color by Rules

{
  "properties": {
    "fontColor": {
      "expr": {
        "Conditional": {
          "Cases": [
            {
              "Condition": { "Comparison": { "Left": { "Measure": "..." }, "Right": { "Literal": { "Value": "0" } } } },
              "Value": { "Literal": { "Value": "'#FF0000'" } }
            }
          ],
          "Else": { "Literal": { "Value": "'#00FF00'" } }
        }
      }
    }
  }
}

Boundaries and Constraints

DO

Always validate JSON syntax before saving
Use unique name values for all visuals
Reference only existing tables and measures
Test visuals after creating page files
Keep visual positions within page bounds
Use z ordering for overlapping visuals

DO NOT

Never hardcode data values in visuals
Never reference non-existent measures
Never use duplicate visual names
Never exceed page width/height bounds
Never modify auto-generated IDs without testing

Workflow Integration

After creating visuals:

Open in Power BI Desktop - Validate the report loads
Check data binding - Verify visuals show correct data
Test interactions - Confirm cross-filtering works
Validate - Use the best-practices skill for quality checks

Common Issues

"Visual won't render"

Check JSON syntax (use JSON validator)
Verify all table/measure references exist
Ensure position is within page bounds

"No data displayed"

Verify queryRef matches the field path
Check that measures are defined in semantic model
Confirm table relationships exist

"Page won't load"

Validate page.json has required properties
Check $schema reference is correct
Ensure name follows expected format
