# @baseline-types
Determines the type of baseline to use in conjunction with the @baselines directive
## Quick Reference
```sql
-- @baseline-types: min, max, average, median
```
## Valid Values
`List`
A comma separated list of types that matches the order of columns defined in @baselines
* average
* min
* max
* median
{% hint style="info" %}
Used in conjunction with [@baselines](/reference/directives/baselines.md)
{% endhint %}
## Full Example
```sql
-- @chart: column
-- @title: Baselines - Multiple Baseline Types on one Series
-- @subtitle: An example column chart showing sales by month
-- @formats: currency
-- @series: Sales
-- @baselines: Sales, Sales, Sales
-- @baseline-types: average, min, max
SELECT
TRUNC(date_closed, 'MONTH') as Month,
sum(amount) as Sales
FROM sales
GROUP BY TRUNC(date_closed, 'MONTH')
ORDER BY TRUNC(date_closed, 'MONTH') ASC
```
## Use Cases
By default, 'average' is used for all baselines. You use baseline-types to override when you want something other than average.
