What Is Malloy
Bar Charts
The examples below all use the following semantic model.
source: flights is duckdb.table('../data/flights.parquet') extend { join_one: carriers is duckdb.table('../data/carriers.parquet') on carrier = carriers.code measure: flight_count is count() aircraft_count is count(tail_num) }
Line charts take two or three parameters.
First parameter - X-axis is time field or numeric expression
Second parameter - Y-axis is a numeric expression
Third (optional) Pivot is dimensional field (numeric or string)
Single line line_chart
# line_chart run: flights -> { group_by: departure_month is dep_time.month aggregate: flight_count }
