Hidden Column

Hidden columns are useful in cases where we do not want the fields to participate in the visualization, but only to be used for linking, filtering and view data.  

Hidden column

We can configure both measure and dimension fields into the hidden column. For measures, we will have all the settings we have for measure fields except formatting and filtering.

Measure

In the case of dimension fields, we will have the following options only. For date fields, we will have all available types except sorting, relative date filter, settings, and filters.

Dimension

Date field

Linking

The primary use case of hidden columns is linking. By configuring hidden columns, the fields configured in hidden columns are listed in the linking section. By configuring the column in linking, we can pass the corresponding column value in the linking parameter.

Measure Based Example: If we want to pass the number of matches played as a URL parameter but do not want it to influence the visualization, we can configure the matches in the hidden columns and incorporate them into the link.

Linking

Dimension Based Example: If we want to pass the team name as a URL parameter but do not want it to influence the visualization, we can configure the team name in the hidden columns and incorporate them into the link.

Linking

Filtering

You can use hidden columns to filter data in the visualizations. To configure hidden columns, click on the filter icon below.

Filtering

Next, click on the Custom button highlighted in the filter configuration dialog image below. This will display a list of all the fields configured in the widget. Keep the field configured in the hidden column and remove the other fields, then click the Update button.

Filtering

Now, in the image below, you can see that the data is filtered based on the hidden column field instead of the actual column that we bound in the widget. 

Filtering

For more details about filtering the widget data, refer to the Cross Filter Configuration documentation.

View Data

You can view the data in the hidden columns in the underlying data view. This is useful for checking the data in more detail and can help you identify any issues with the data.

View data

NOTE: We do not recommend configuring lower hierarchy data in hidden columns, as indicated by the info icon in the Hidden Column section.

Hidden Column

The below chart displays the goals by each team without hidden columns.

Before

If we configure lower hierarchy data (Player Name) in hidden columns compared to column filed data, the data configured in the widgets gets duplicated, and individual columns are split based on the hidden column field. This affects the chart visualization, as can be seen in the image below.

After
