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 |

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
namevalues for all visuals - Reference only existing tables and measures
- Test visuals after creating page files
- Keep visual positions within page bounds
- Use
zordering 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-practicesskill 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
queryRefmatches 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
$schemareference is correct - Ensure
namefollows expected format
