### Use cases
|
||||
|
||||
This transformation transforms rows into separate fields. This can be useful as fields can be styled
|
||||
and configured individually, something rows cannot. It can also use additional fields as sources for
|
||||
data driven configuration or as sources for field labels. The additional labels can then be used to
|
||||
define better display names for the resulting fields.
|
||||
|
||||
Useful when visualization data in:
|
||||
* Gauge
|
||||
* Stat
|
||||
* Pie chart
|
||||
|
||||
### Configuration overview
|
||||
|
||||
* Select one field to use as the source of names for the new fields.
|
||||
* Select one field to use as the values for the fields.
|
||||
* Optionally map extra fields to config properties like min and max.
|
||||
|
||||
### Examples
|
||||
|
||||
Input:
|
||||
|
||||
Name | Value | Max
|
||||
--------|-------|------
|
||||
ServerA | 10 | 100
|
||||
ServerB | 20 | 200
|
||||
ServerC | 30 | 300
|
||||
|
||||
Output:
|
||||
|
||||
ServerA (max=100) | ServerB (max=200) | ServerC (max=300)
|
||||
------------------|------------------ | ------------------
|
||||
