When querying datasets with the GraphQL Data APIs, you can now bucket time series data by common grains (day, week, etc) and aggregate data within time buckets. You can also groupBy other dimensions to segment the data. Check out our docs for more info!

query {
    purchasesQuery(
      filter: {
        item_type: {
          in: ["pants", "skirts", "shorts"]
        }
        payment_status: {
          eq: "successful"
        }
      }
      groupBy: [purchase_timeDay,item_type]
    ) {
      purchase_amountSum 
      purchase_timeDay 
      item_type 
    }
}
