# //@directive: comments

When developing, sometimes you may wish to quickly toggle on/off the directive without removing it from your source code. ChartSQL supports "directive comments" which will disable that directive.

You comment a directive by adding two forward slashed directly before the @ symbol

```sql
-- @chart: column
-- @title: Directive Comments
-- @subtitle: An example of commenting out a directive
-- @formats: currency
-- @series: Sales
-- //@baselines: Sales
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;
```
