====== Random Data Generator ======


===== About =====
A ''random generator'' is a [[data-supplier|column data supplier]] that [[generator|generates]] data randomly inside a range of values.


<note tip>
If you want to extract values from a list at random, you should use the [[histogram|histogram generator]] with a factor of ''1'' for each bucket. Example: [[howto:generator:random_color]]
</note>


This generator will generate the values in an uniform distribution.
