### How do I set up links between selectors? {#how-to-configure-link-between-selectors}

To set up links:

1. Go to the dashboard page.
1. At the top of the page, click **Edit**.
1. To the right of the widget to set up a [link](../dashboard/link.md) for, click ![image](../../_assets/datalens/links.svg) and select the link type with the selector you need.

The link between selectors built on the same dataset is established automatically and does not require additional configuration.

{% note warning %}

Before creating a link, make sure the field used by the selector as a filter is included in the dataset the chart is built on. For more information, see [Joining Yandex DataLens data](../concepts/data-join.md).

{% endnote %}

### Why are there no values available in the dashboard selectors? {#unavailable-selector-values}

If the dashboard contains a selector based on a dataset [parameter](../concepts/parameters.md), unlink this selector from any others on the dashboard tab (set **Not linked** as the [link](../dashboard/link.md) type).

### How do I apply one filter to two datasets on a dashboard? {#how-to-apply-filter-to-two-datasets}

Link the selector and the chart (from another dataset).

Links between selectors and charts are set up using the **Links** button in the dashboard editing section.

### How do I set up selectors to list only the elements pertaining to a specific dataset sample? {#how-to-configure-selectors}

There are several ways to do this:

* Select **Manual input** as the selector type and list the values in question. After creating the selector, set up links between the selector and charts on the dashboard. Use this method if values do not change depending on the sample.
* Create a new selector and use the link to filter out values in the selector in question.
* Use a calculated field:
   * Create a calculated field that defines a list of values. Here is an example: `CASE ([country], "BY", "CIS", "KZ", "CIS", "RU", "CIS", "Other countries")`.
   * Output this field as an additional selector and set its default value to `"CIS"`.
      In this case, in the second selector, the default values will be `"BY"`, `"KZ"`, and `"RU"`.
* If no other values are used, create a dataset with the specified values and create a selector based on this dataset. Link the selector to the chart.

### What do I do if a chart is not displayed on a published dashboard?

1. Open the dashboard publishing menu by clicking ![image](../../_assets/console-icons/nodes-right.svg).
1. Check that all the dashboard objects are published.

### How do I publish a dashboard containing Metrica or AppMetrica data? {#how-metrica-appmetrica-share}

You cannot publish such a dashboard.

To share a dashboard containing Metrica or AppMetrica data, use one of the following methods:

* [Add](../security/add-new-user.md) a user to your organization or cloud and grant them access to a dashboard or chart.
* [Export](connections.md#uploading-data-logs-api) data to a [Managed Service for ClickHouse®](../../managed-clickhouse/index.md) cluster and use a connection to the ClickHouse® database as a source.
