# About transformations
|
||
|
||
Transformations process the result set of a query before it’s passed on for visualization. Using transformations, you can:
|
||
|
||
- Rename fields
|
||
- Join time series data
|
||
- Perform mathematical operations across queries
|
||
- Use the output of one transformation as the input to another transformation
|
||
|
||
For users that rely on multiple views of the same dataset, transformations offer an efficient method of creating and maintaining numerous dashboards.
|
||
|
||
You can also use the output of one transformation as the input to another transformation, which results in a performance gain.
|
||
|
||
> Sometimes the system cannot graph transformed data. When that happens, click the `Table view` toggle above the visualization to switch to a table view of the data. This can help you understand the final result of your transformations.
|
||
|
||
## Transformation types
|
||
|
||
Grafana provides a number of ways that you can transform data. For a complete list of transformations, refer to [Transformation functions]({{< relref "transformation-functions/" >}}).
|
||
|
||
## Order of transformations
|
||
|
||
When there are multiple transformations, Grafana applies them in the order they are listed. Each transformation creates a result set that then passes on to the next transformation in the processing pipeline.
|
||
|
||
The order in which Grafana applies transformations directly impacts the results. For example, if you use a Reduce transformation to condense all the results of one column into a single value, then you can only apply transformations to that single value.
