Changes in basic featuresChanges in basic features

• Implemented agent mode for Neuroanalyst on the dashboard. In this mode, Neuroanalyst analyzes the dataset your dashboard is based on and can respond by selecting a chart or building a new one based on the dataset. For context, it uses the dataset and a reference tab. When in agent mode, Neuroanalyst uses charts from the reference tab as templates for new charts.

  You can enable Neuroanalyst's agent mode in its settings on the dashboard:

  1. If the Neuroanalyst option is off, turn it on (on by default).
  2. Enable the Agent mode option.
  3. Select a reference tab if your dashboard has more than one tab.
  4. Optionally, hide the reference tab in the dashboard settings.

  When selecting a reference tab, please follow these recommendations:

  • On the tab, place wizard charts that describe your dataset in various aspects and answer different questions.
  • In the descriptions of your dashboard charts or widgets, provide examples of questions they help answer.
  • Instead of tab selectors, use filters in charts to make your charts answer more specific questions.
  • Use charts built on a single dataset.
  • Use relevant field descriptions in the dataset.

  Current limitations:

  • Works only on one dataset, the one your reference tab is based on.
  • The titles of the first three charts get into Neuroanalyst's recommendations.

  Try out Neuroanalyst's agent mode on the public demo dashboard (click in the bottom-right corner).
  Also see the reference tab example.

• Implemented the ability to add Neuroanalyst to the dashboard and report as a separate Insight widget.

  This widget displays Neuroanalyst's insights for the selected chart on the current dashboard tab or report page. When adding a widget, you can set a custom prompt asking about the data. When you save a dashboard or report, the system will analyze the chart you specify and return its findings based on the chart and custom prompt data. The result will be updated every time you open the dashboard or report.

• Updated dashboard mailing lists:

  • Now, within a single mailing list, you can set up multiple states with sets of attached screenshots in the email, e.g., for each of the tabs.
  • Added the screenshot auto height setting.
  • Added the ability to specify the date in the attached file's name.
  • Implemented the ability to select several users in a separate window.

• Added new dashboard style options:

  • Dashboard background separately for light and dark themes.
  • Background and transparency separately for light and dark themes for all dashboard widgets.
  • Rounding for all dashboard and report widgets separately for light and dark themes.

• Added the ability to save a draft version of the dataset.

  A draft is a version containing unsaved dataset changes. Common users see none of the changes made to the draft. The charts and dashboards based on it remain unchanged. This allows you to hide dataset edits until you actualize your version.

  To create a draft after you have edited a dataset, click the check mark in the top-right corner and select Save as draft.

  To apply changes to visualizations, in draft view mode, click Make actual.

Fixes and improvementsFixes and improvements

• Added the ability to upload files when importing a workbook via drag and drop.

• Added the ability to select a range of objects in the list of workbooks and collections: hold down the Shift key and mark the beginning and end of the range with your mouse.

• Updated the embed and public access settings dialog. To access the settings, click → Share at the top of the chart or dashboard and select a tab:

  • In organization: To set up access to a workbook or share a link within an organization.
  • Publicly: To set up public access via a link for external users.
  • Embed: To embed private objects.

• Fixed the context menu for shared objects in the navigation bar.

• Fixed a bug where breadcrumbs were not automatically updated when copying a workbook from a nested collection.

• Provided the ability to change the chart and dashboard background color using special parameters in the link:

  • _bg_color: Sets the background color of:

    • Private charts and dashboards in hexadecimal format, e.g., _bg_color=D7F7F7.
    • Public charts and dashboards in hexadecimal format, only if _embedded equals 1, e.g., _bg_color=D7F7F7&_embedded=1.

  • _widgets_bg_color: Sets the background color of:

    • Private dashboard widgets in hexadecimal format, e.g., _widgets_bg_color=B7F7F7.
    • Public dashboard widgets in hexadecimal format, only if _embedded equals 1, e.g., _widgets_bg_color=B7F7F7&_embedded=1.

Dashboard fixesDashboard fixes

• Changed inserting a copied selector with display settings on Selected tabs. Now, if you select the following in the insert dialog box:

  • Copy: Creates an independent selector on the current tab.
  • Update settings: After the insertion, the original selector's Show in tabs setting will be automatically updated.
  • If you close the window, the selector will not be inserted.

• The mobile widget order menu now gives access to global selectors.

• You can now reset the appearance of the dashboard itself or the dashboard and all charts on it. Do it in dashboard editing mode by clicking to the right of the Appearance section's name and select Reset dashboard appearance or Reset the appearance of dashboard and all charts.

• Added a restriction for widgets featuring a group of selectors: you can no longer save a group in which several selectors refer to the same parameter. Previously, this restriction applied only to manual selectors; now it also applies to dataset selectors.

• Added a missing parameter message when opening the dashboard settings window.

• Now you can add questions for the Neuroanalyst chat in the dashboard settings in Neuroanalyst's agent mode. By default, questions are taken from descriptions and titles of the first three widgets on the reference tab. To ask your own questions, go to the dashboard settings:

  1. If the Neuroanalyst option is off, turn it on (on by default).
  2. Enable the Agent mode option.
  3. [Select a reference tab](../operations/dashboard/dashboard-ai-reference-tab.md) if your dashboard has more than one tab.
  4. Opposite to Example questions, click and, in the window that opens, enter your questions to Neuroanalyst. These questions will be displayed when you launch Neuroanalyst.
  5. Optionally, hide the reference tab in the dashboard settings.
