Data Aggregation Methods

Aggregation is how ChartGen summarizes your data. Understanding these methods helps you get exactly the visualization you need. Our AI automatically selects the most appropriate aggregation based on your data and natural language description, but you can override this choice at any time.

Sum

Add all values together

Total sales = $1,000 + $2,000 + $3,000 = $6,000

Best for: Revenue totals, quantity counts, cumulative metrics

Average

Calculate the mean of all values

Average price = ($10 + $20 + $30) / 3 = $20

Best for: Average order value, mean temperature, typical performance

Count

Count the number of records

Number of orders = 150 orders

Best for: Transaction counts, visitor counts, event frequency

Min

Find the smallest value

Lowest price = $5.99

Best for: Minimum temperature, lowest bid, earliest date

Max

Find the largest value

Highest score = 98 points

Best for: Peak performance, maximum capacity, record values

Count Distinct

Count unique values only

Unique customers = 45 (from 100 orders)

Best for: Unique visitors, distinct products sold, different categories
