Macro example | Description
------------ | -------------
*$__time(dateColumn)* | Will be replaced by an expression to rename the column to `time`. For example, *dateColumn as time*
*$__timeEpoch(dateColumn)* | Will be replaced by an expression to rename the column to `time` and converting the value to unix timestamp. For example, *extract(epoch from dateColumn) as time*
*$__timeFilter(dateColumn)* | Will be replaced by a time range filter using the specified column name. For example, *dateColumn BETWEEN '2017-05-10T10:06:23Z' AND '2017-05-10T10:06:23Z'*
*$__timeFrom()* | Will be replaced by the start of the currently active time selection. For example, *'2017-05-10T10:06:23Z'*
*$__timeTo()* | Will be replaced by the end of the currently active time selection. For example, *'2017-05-10T10:06:23Z'*
*$__timeSec(dateColumn)* | Will be replaced by an expression to rename the column to `time` and converting the value to unix timestamp. For example, *extract(epoch from dateColumn) as time*
*$__timeFilter(dateColumn)* | Will be replaced by a time range filter using the specified column name. For example, *dateColumn BETWEEN '2017-04-21T05:01:17Z' AND '2017-04-21T05:06:17Z'*
*$__timeFrom()* | Will be replaced by the start of the currently active time selection. For example, *'2017-04-21T05:01:17Z'*
*$__timeTo()* | Will be replaced by the end of the currently active time selection. For example, *'2017-04-21T05:06:17Z'*
*$__timeGroup(dateColumn,'5m')* | Will be replaced by an expression usable in GROUP BY clause. For example, *(extract(epoch from dateColumn)/300)::bigint*300 AS time*
*$__timeGroup(dateColumn,'5m', 0)* | Same as above but with a fill parameter so all null values will be converted to the fill value (all null values would be set to zero using this example).
*$__unixEpochFilter(dateColumn)* | Will be replaced by a time range filter using the specified column name with times represented as unix timestamp. For example, *dateColumn >= 1494410783 AND dateColumn <= 1494497183*
