# Data-slicer

**The Data Slicer provides an interface for filtering the Microreact project's display by limiting the data shown, based on a preselected column.**

The filtering done with a Data Slicer is the same functionality as filtering from within the metadata table, but simplified to show only a single column. It's useful when the data contain many columns, or when there is a column frequently used for filtering.

### Add a Data Slicer panel using the edit panels button ![](https://92463871-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MCM3b1nzgmsPUEa2xap%2Fuploads%2Fgit-blob-174ac7dccab4d4754bbc8d6f0c2177aa56912241%2Fedit-panels.png?alt=media)

* Choose a data column that you want to filter the data by (each of these will become a checkbox)
* Choose a Group if you want sub-sections in the listing of checkboxes and the option to colour by a different level of detail.
* Choose whether to show bars (and whether to colour them). The bars represent the number of data rows represented by that value.
* Choose whether to sort the existing values in alphabetical order or by frequency of occurrence.
