Dashboards in Yandex DataLens

Dashboards are pages or sets of pages that contain widgets. They let you group charts in one place and add explanatory text and titles.
You can create new dashboard pages using the tab element.

Display modes

DataLens lets you display the dashboard in full-screen mode. This mode hides part of the interface elements and expands the widget area on the screen.

On the mobile version of the dashboard, DataLens displays the charts one after another using the following sorting rule: left-to-right, top-to-bottom.

Widgets

Widgets are dashboard elements. You can create links between selector and chart widgets.

Yandex DataLens offers the following types of widgets:

• Chart
• Selector
• Text
• Title

Chart

Visualization as a table or chart.
You can place charts anywhere on a dashboard and change their size.
Charts can be linked to selectors.

For more information about charts, see Charts.

Selector

A filter that affects query results on its linked widgets. To add a selector to a dashboard, go to Adding selectors to dashboards.
The selector can be linked to a chart or another selector.
For more information, see Link.
A selector works within a single dashboard tab.

Text

A widget represented as text. It lets you place things like a set of links or explanatory captions on a dashboard. The Markdown markup language is supported.
For more information about Markdown markup, see Using Markdown in DataLens.

Title

A widget represented as a heading. It lets you differentiate charts by meaning and divide them into groups within a single dashboard page.

Link

Links determine how a selector affects one or more charts or other selectors. By default, selectors are linked with charts created within a single dataset. Selectors and charts based on different datasets can also be linked manually using aliases.

You can choose an existing dataset field as the link or create your own field where you manually set the selector values.

You can use links to filter the values of selectors and charts. For example, if you select a country in the first selector on the dashboard, the second selector limits the list of cities (and vice versa).

The link type determines how values in selectors and charts are filtered. The type is set in the links window in dashboard edit mode.
You can use the following types of links for a pair of widgets:

• Link, for widgets that mutually affect each other.
• Incoming link, when a widget is affected by a widget.
• Outgoing link, when a widget affects another widget.
• Ignore, for widgets that mutually ignore each other.
• No link, for widgets from different datasets or widgets that can't be linked.

Some widgets can't affect other widgets. Possible types of links between widgets are shown in the table:

Affects/Affected	Selector	Charts
Selector	Link Incoming link Outgoing link Ignore	Outgoing link Ignore
Chart	Incoming link Ignore	—

An alias

An alias is a link between fields of different datasets, which determines how widgets impact each other when you link them.

Aliases let you link widgets that are based on different datasets. For example, if you create an alias using the [Region] and [Country] fields from different datasets, a selector by the [Region] field from one dataset will filter data in a chart with the [Country] field of another dataset. For widgets based on the same dataset, aliases are created automatically. Creating aliases is required when you need to:

• Establish links between selectors that are based on different datasets, so that the values of one selector filter the list of available values of another selector.

• Establish links between a selector of the Based on datasets type from one dataset and charts from another dataset, so that the selector values filter the values in the charts.

• Establish links between a selector of the Manual input type and other selectors, so that the values of one selector filter the list of available values of another selector.

You can specify an alias for a pair of linked widgets. In this case:

• Multiple aliases can be set for a single pair of widgets.
• An alias set for one pair of widgets is applied to all linked widgets that are based on the same datasets (which use the fields specified in the alias).
• An alias works within a single dashboard tab.
• To limit the use of an alias, set the Ignore type for a link between widgets.

For more information about how to create aliases, see Creating an alias.

You can delete links from an alias where more than two fields are linked. For more information, see Deleting an alias field.

Publishing dashboards

You can grant any internet user access to a dashboard using DataLens Public. This dashboard becomes public and any user can view it without authorization.

Access management

You can configure dashboard permissions. For more information, see Managing access to DataLens.
