+===== Transformations =====
-  * The default transformation doesn't map any values, leaving cell values "as is".
-  * Linear transformation will map linearly any values between the "from" and "to" ranges.
+  * **None**: The default transformation doesn't map any values, leaving cell values "as is".
-  * Equalize will construct a curve based on [[http://en.wikipedia.org/wiki/Equalization|Equalization]]
+  * **Linear**: This transformation will map linearly any values between the "from" and "to" ranges.
+  * **Equalize**: This transformation will construct a curve based on [[wp>Equalization]].
