# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.microreact.org/instructions/adding-and-editing-panels/data-slicer-panel.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
