# 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 ![](/files/XcMtTPK5Zh15QXX1GBlP)

* 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.
