Managing dashboard site settings

Cloudera Data Visualization is highly configurable, with many site-wide settings. You can turn specific dashboard related features on and off and adjust various settings for visuals, dashboards, and snapshots.

The Site Settings menu is only available to users with administrative privileges.

Click the icon on the main navigation bar to open the Administration menu and select Site Settings.

The Site Settings interface opens on the Data page.
Open the Dashboards menu from the left navigation and select one of the options available.

Visuals

You can enable various advanced options for visuals.

The Site Settings menu is only available to users with administrative privileges.

Enable explore

You can use the explore function to find the best visualization for your data request. It suggests new visual types and options based on the information you already use in existing visuals. For more information, see Exploring visual options.

To enable this function, select the Enable Explore option under Dashboards > Visuals in the site settings.

Enable visual transitions

You can use transitions to animate visuals during loading and refresh operations. The visual types that use visual transitions include bars, lines, combo, area, scatter, grouped bar, histogram, sparklines, pie, packed bubbles, and correlation heat map.

To enable the transition function, select the Enable Visual Transitions option under Dashboards > Visuals in the site settings.

Set maximum count of trellises to be displayed before warning

To adjust the maximum count of trellises, select the appropriate value for Max Count Of Trellises To Be Displayed Before Warning under Visuals.

Set maximum data results size for visuals and downloads

To adjust the maximum data results size, enter a value in the Maximum data results size for visuals and downloads (in MB) text box under Dashboards > Visuals.

Set maximum data rows for visuals

You can provide an upper limit for the number of rows rendered in a visual request. Sometimes an inexperienced or malicious user can create a visual requesting billions of rows. This may result in excessive resource consumption at the server level and the result might be too large to render in the client browser.

To avoid this scenario and provide an upper limit on the number of rows rendered, enter a value in the Maximum data rows for visuals text box under Dashboards > Visuals in the site settings.

At the individual visual level, the setting in the Maximum number of rows to fetch option in the Data menu of the Visual Designer overrides this default behaviour.

At the site level, the setting in the Maximum data rows for visuals option overrides the setting in the Maximum number of rows to fetch option.

Set maximum width of canvas visuals

Cloudera recommends that you designate a reasonable maximum width for canvas visuals considering performance reasons. Overly wide visuals that display streaming data may cause the Internet browser to crash.

To set the maximum width value, enter a value in the Maximum width of canvas visuals text box under Dashboards > Visuals in the site settings.

Enable custom styles

You can enable custom styling to set the appearance of visuals, dashboards, filters, and applications through CSS and JS scripting. For more information on using custom styles, see Adding custom styles to visuals.

To enable the feature, check the Enable Custom Styles option under Dashboards > Visuals in the site settings.

Show descendant dashboard information

You can choose to show descendant dashboard information on the Visuals page.

To enable the feature, check the Show Descendant Dashboard information on the Visuals page option under Dashboards > Visuals in the site settings.

Enable legacy crosstab visual

You can make the legacy crosstab visual type available to users.

To enable the feature, check the Enable legacy crosstab visual option under Dashboards > Visuals in the site settings.

Enable the search visual

You can only add the search visual to the Visual Catalog if Search is enable under Site Configuration. Once you have enabled search, the two associated options are also automatically enabled:

Enable Search Visual: You can find it under Dashboards > Visuals
Enable Search in Menu Bar: You can find it under Site Configuration.

Set CSV/Excel download as default

In Cloudera Data Visualization, you can download data in a visual in CSV or Excel format.

To make this download option default, check the Enable "Download as CSV/Excel" by default option under Dashboards > Visuals.

Set maximum data rows for download requests

Sometimes an inexperienced or malicious user can download a large number of rows. This may result in excessive resource consumption at the server level.

To avoid this scenario and provide an upper limit on the number of rows downloaded in a CSV file, enter a value in the Maximum data rows for download requests text box under Dashboards > Visuals.

Snapshots

The group of snapshot settings enables you to take snapshots of your actual visuals and dashboards, which you can then download as PNG files.

The Site Settings menu is only available to users with administrative privileges.

Snapshots replace the standard thumbnails that appear in the Visuals interface with miniaturized versions of the visual or dashboard. This customization makes it very easy to locate the visuals and dashboards you want to use.

You can configure the following settings:

Check Enable snapshots (required for thumbnails, email, and image downloads).
Check Enable "Download as Image/PDF" by default
Set the IP/Hostname to use to connect back to the server. You can use the default value or change it to connect to a different server.

The Site Settings menu is only available to users with administrative privileges.

Config

You can perform the following dashboard configuration actions:

The Site Settings menu is only available to users with administrative privileges.

Set default width of dashboards

To specify a width for dashboards, enter the measurement for Default Dashboard Width in pixels.

Set warning that loading dashboards takes too long in view mode

To set the warning, check the Show "This dashboard is still loading data" in view mode option under Dashboards > Config in the site settings.

Interactive Map

The Site Settings menu is only available to users with administrative privileges.

Enable API keys for interactive map visuals

Your organization must obtain its own credentials for Google Maps, either Google API Id or Google Client Id. To obtain Google Maps keys, see Google Maps APIs.

For the Mapbox interface, your organization must get a Mapbox Token and the Mapbox Style ID, specified for each visual in the Settings menu. Cloudera Data Visualization already has a default mapbox token. To obtain new Mapbox tokens and Style IDs, see Mapbox.

Specify atlas mapbox server

You can use a Mapbox server or specify an Atlas Mapbox server at the site level to run Mapbox APIs on your own infrastructure, whether on your own private cloud or on-premises.

To specify an Atlas Mapbox server at the site level, Enter the IP address or hostname of the Atlas Mapbox server in the IP/Hostname of Atlas Mapbox Server (optional) text box.
