====TravelWriterProfile (Analytic Filter)====

===Description===
The **TravelWriterProfile** filter very similar to [[filter_travelwriter|TravelWriter]] - it's used to write values when items are in a certain point in your process or physical location.

The primary difference is that this version of the filter uses multiple columns as an input.

===Parameters===
^Name^Default^Meaning^
|Channel|//<blank>//|The column to use as the moving/state-changing axis|
|Min|0|The minimum element in the array|
|Max|100|The maximum element in the array|
|Function|max|The function (//min// or //max//) that determines which value is stored in each array element|

===Example===
<code>
<filter type="TravelWriterProfile">
     <channel>Position</channel>
     <min>0</min>
     <max>5</max>
     <function>min</function>
</filter>
</code>

//Records the a value as Position changes over a range of 0-5//
