title: Data links and actions options
comments: |
  There are four data link shared files, datalink-options.md, datalink-options-1.md, datalink-options-2.md, and datalink-options-3.md to cover the most common combinations of options. 
  Using shared files ensures that content remains consistent across visualizations that share the same options and users don't have to figure out which options apply to a specific visualization when reading that content.
  This file is used in the following visualizations: bar chart, candlestick, state timeline, status history, time series, trend, xy chart

_Data links_ allow you to link to other panels, dashboards, and external resources and _actions_ let you trigger basic, unauthenticated, API calls.
In both cases, you can carry out these tasks while maintaining the context of the source panel.

For each data link, set the following options:

- **Title**
- **URL**
- **Open in new tab**
- **One click** - Opens the data link with a single click. Only one data link can have **One click** enabled at a time.

For each action, define the following API call settings:
